Криптография (Cryptography) Шифрование данных и дешифровка Encryption and Decryption RSA
 
02:03
Криптография - это наука об обеспечении безопасности данных. Она занимается поисками решений четырех важных проблем безопасности - конфиденциальности, аутентификации, целостности и контроля участников взаимодействия. Шифрование - это преобразование данных в нечитабельную форму, используя ключи шифрования-расшифровки. Шифрование позволяет обеспечить конфиденциальность, сохраняя информацию в тайне от того, кому она не предназначена. ➤ Для удобства участникам передачи зашифрованного сообщения дают следующие имена: Алиса — отправитель, Боб — получатель, Ева — пассивный перехватчик, Меллори (Man-in-the-middle) — активный перехватчик, может не только перехватывать передачу, но и подменять содержимое. ➤ Криптография не занимается: защитой от обмана, подкупа или шантажа законных абонентов, кражи #ключей и других угроз информации, возникающих в защищенных системах передачи #данных. ➤ Криптография — одна из старейших наук, её #история насчитывает несколько тысяч лет. Ещё в древнем Риме Гай Юлий Цезарь, который совершенно не доверял гонцам, опасаясь что те прочтут его письма, прибегал к #шифрам. Для того, чтобы избежать вероятности того, что гонец всё же осмелится и захочет прочесть послание Цезаря, он, отправляя письма генералам, менял каждую букву на D, каждую B на E, и так далее. И лишь те, кто знал правило «сдвига на 3» мог расшифровать его послание. Проблема защиты информации и сегодня является наверное одной из самых актуальных. Шифрованием, кодированием и многими другими методами, созданными для обеспечения конфиденциальности информации занимается одна из древнейших наук – криптография. Какие шифры бывают и есть ли системы шифрования,которые невозможно взломать и раскрыть? Какие методы и системы защиты информации использует криптография? Как можно защитить себя от атаки хакеров? Об этом расскажут: кандидат психологических наук - Сергей Николаевич Ениколопов, кандидат физико-математических наук - Иван Владимирович Чижов и доктор физико-математических наук - Владимир Сергеевич Анашин ➤ Изначально криптография изучала методы шифрования информации — обратимого преобразования открытого (исходного) текста на основе секретного #алгоритма или ключа в шифрованный #текст (шифротекст). Традиционная #криптография образует раздел симметричных криптосистем, в которых зашифрование и расшифрование проводится с использованием одного и того же секретного ключа. Помимо этого раздела современная криптография включает в себя асимметричные криптосистемы, системы электронной цифровой подписи (ЭЦП), хеш-функции, управление ключами #key, получение скрытой информации, #квантовую криптографию. ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ►► ► ► ► ► ► ► ► ► ► ► ICOTRACKER.NET специализируется на оценке компании с запланированным ICO "ИКО".

DEF CON 23 - Crypto and Privacy Village - Craig Young - Smart Home Invasion
 
22:10
SMART HOME INVASION Craig Young @craigtweets BIO: Craig is a computer security researcher with Tripwire's Vulnerability and Exposures Research Team (VERT). He has identified and disclosed dozens of vulnerabilities in products from Google, Amazon, IBM, NETGEAR, Adobe, HP, and others. His research has resulted in numerous CVEs and recognition in the Google Application Security Hall of Fame. Craig won in track 0 and track 1 of the first ever SOHOpelessly Broken contest at DEF CON 22 by demonstrating 10 0-day flaws in SOHO wireless routers. ABSTRACT: Smart home technology has been a dream for many perhaps inspired by the likes of George Jetson. Unfortunately the technology is in its infancy still and the question remains as to whether vendors can demonstrate the ability to make our homes smarter without simultaneously introducing new risks to personal safety and privacy. In an effort to answer this question, Tripwire VERT conducted a security assessment of the three top-selling ‘Smart Home Hub' products available on Amazon. The research revealed 0-day flaws in each product allowing an attacker to control smart home functionality. This presentation will reveal some of the findings from this study including vulnerability discoveries. If not addressed, smart home flaws can give rise to a new type of ‘smart criminal' able to case victims without being seen. Once a target is chosen, it is possible to unlock doors and disable security monitoring. REASON: Each product I tested had 0-day flaws Two of the three products evaluated contained 0-day flaws allowing a remote attacker to gain root access with limited to no user-interaction required. I will be demonstrating a PoC which determines the local IP address and searches for the vulnerable device. The PoC described in #3 is still 0-day in official firmware, the latest RC firmware, and possibly in the latest beta firmware.

What is BLIND SIGNATURE? What does BLIND SIGNATURE mean? BLIND SIGNATURE meaning & explanation

What is BLIND SIGNATURE? What does BLIND SIGNATURE mean? BLIND SIGNATURE meaning - BLIND SIGNATURE definition - BLIND SIGNATURE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography a blind signature as introduced by David Chaum is a form of digital signature in which the content of a message is disguised (blinded) before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature. Blind signatures are typically employed in privacy-related protocols where the signer and message author are different parties. Examples include cryptographic election systems and digital cash schemes. An often-used analogy to the cryptographic blind signature is the physical act of a voter enclosing a completed anonymous ballot in a special carbon paper lined envelope that has the voter's credentials pre-printed on the outside. The ballot can be marked through the envelope by the carbon paper. The voter hands the sealed envelope to an official who verifies the credentials and signs it. Once signed, the package is given back to the voter, who transfers the now signed ballot to a new unmarked normal envelope. Thus, the signer does not view the message content, but a third party can later verify the signature and know that the signature is valid within the limitations of the underlying signature scheme. Blind signatures can also be used to provide unlinkability, which prevents the signer from linking the blinded message it signs to a later un-blinded version that it may be called upon to verify. In this case, the signer's response is first "un-blinded" prior to verification in such a way that the signature remains valid for the un-blinded message. This can be useful in schemes where anonymity is required. Blind signature schemes can be implemented using a number of common public key signing schemes, for instance RSA and DSA. To perform such a signature, the message is first "blinded", typically by combining it in some way with a random "blinding factor". The blinded message is passed to a signer, who then signs it using a standard signing algorithm. The resulting message, along with the blinding factor, can be later verified against the signer's public key. In some blind signature schemes, such as RSA, it is even possible to remove the blinding factor from the signature before it is verified. In these schemes, the final output (message/signature) of the blind signature scheme is identical to that of the normal signing protocol. Blind signature schemes see a great deal of use in applications where sender privacy is important. This includes various "digital cash" schemes and voting protocols. For example, the integrity of some electronic voting system may require that each ballot be certified by an election authority before it can be accepted for counting; this allows the authority to check the credentials of the voter to ensure that they are allowed to vote, and that they are not submitting more than one ballot. Simultaneously, it is important that this authority does not learn the voter's selections. An unlinkable blind signature provides this guarantee, as the authority will not see the contents of any ballot it signs, and will be unable to link the blinded ballots it signs back to the un-blinded ballots it receives for counting. Blind signature schemes exist for many public key signing protocols. Some examples are provided below. In each example, the message to be signed is contained in the value m. m is considered to be some legitimate input to the signature function. As an analogy, consider that Alice has a letter which should be signed by an authority (say Bob), but Alice does not want to reveal the content of the letter to Bob. She can place the letter in an envelope lined with carbon paper and send it to Bob. Bob will sign the outside of the carbon envelope without opening it and then send it back to Alice. Alice can then open it to find the letter signed by Bob, but without Bob having seen its contents. ....

What is QUANTUM KEY DISTRIBUTION? What does QUANTUM KEY DISTRIBUTION mean? QUANTUM KEY DISTRIBUTION meaning - QUANTUM KEY DISTRIBUTION definition - QUANTUM KEY DISTRIBUTION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Quantum key distribution (QKD) uses quantum mechanics to guarantee secure communication. It enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages. It is often incorrectly called quantum cryptography, as it is the best-known example of a quantum cryptographic task. An important and unique property of quantum key distribution is the ability of the two communicating users to detect the presence of any third party trying to gain knowledge of the key. This results from a fundamental aspect of quantum mechanics: the process of measuring a quantum system in general disturbs the system. A third party trying to eavesdrop on the key must in some way measure it, thus introducing detectable anomalies. By using quantum superpositions or quantum entanglement and transmitting information in quantum states, a communication system can be implemented that detects eavesdropping. If the level of eavesdropping is below a certain threshold, a key can be produced that is guaranteed to be secure (i.e. the eavesdropper has no information about it), otherwise no secure key is possible and communication is aborted. The security of encryption that uses quantum key distribution relies on the foundations of quantum mechanics, in contrast to traditional public key cryptography, which relies on the computational difficulty of certain mathematical functions, and cannot provide any mathematical proof as to the actual complexity of reversing the one-way functions used. QKD has provable security based on information theory, and forward secrecy. Quantum key distribution is only used to produce and distribute a key, not to transmit any message data. This key can then be used with any chosen encryption algorithm to encrypt (and decrypt) a message, which can then be transmitted over a standard communication channel. The algorithm most commonly associated with QKD is the one-time pad, as it is provably secure when used with a secret, random key. In real-world situations, it is often also used with encryption using symmetric key algorithms like the Advanced Encryption Standard algorithm.

Complete Advanced Training: Some employers will require candidates to hold an advanced degree such as a master’s degree in cyber security. Prospective employers may offer tuition assistance to meet this goal. 3. Pass Security Clearances (if applicable) : Security clearances are necessary for those who wish to work with classified information as part of a military of government agency. A variety of agencies issue both personnel and facility security clearances, but most are issued by the Department of Defense. Each type of clearance has its own procedures and paperwork. The process, which takes three months to a year, does not begin until an employer decides to hire you, at which point you receive a conditional offer of employment. The first step is to submit clearance documentation, followed by a Background Investigation. Things you should be familiar with: • Penetration Testing which is the act of testing the security of your network, server, website or app. • System Administration • Network Analysis - Your server will often be connected to a network. So it is important to understand the traffic coming in and out of your server. • Quality Code - Since you’re a coder, make sure you use the best security practices when developing your websites or web apps. Never trust user input. • CLI, Terminal, Command Prompt or Powershell - Learning how to work in the Command Line will help you to work faster and more efficiently. Coming to the Scope: • You get to work with the State departments responsible for IT SEC and Cyber Security on national level (such as Indian CSIRT under the Ministry of Communications and Information Technology) • You can apply for jobs at State departments which are responsible for critical infrastructure and its protection. • You can apply for jobs at Ministry of Defence, partially Ministry of Law and Justice, Ministry of Information and Broadcasting, Ministry of Science and Technology, • Private companies developing, selling or implementing IT SEC or CYBER SEC products. • Universities, faculties of informatics.

A bonus scene from REALITY LOST, a different documentary about quantum mechanics by Karol Jalochowski, the movie produced by Centre for Quantum Technologies (CQT) at National University of Singapore. Christian Kurtsiefer, a Principal Investigator at CQT, explains how and why he hacks quantum cryptographic systems. Dag Kaszlikowski is the host. We filmed this conversation at the Thow Kwang Pottery Jungle. SYNOPSIS When 20th century begun, a major shift took place in science. Scientists started making experiments with an unprecedented precision. Fiddle with single particles, atoms, and electrons. And they got bewildered. Small objects seemed to have a sort of fuzzy properties. What's more - the very act of observing them, of measuring them, seemed to bring them to live, excavate them from a vague domain. Equations of quantum mechanics were beautiful. They did generate astonishingly correct answers for mind boggling questions about the exotic micro world. But there was a price to pay. Objective reality had to go.

Beyond Einstein: In Search of the Ultimate Explanation
 
01:02:50
Albert Einstein spent his last thirty years unsuccessfully searching for a ‘unified theory’ — a single master principle to describe everything in the universe, from tiny subatomic particles to immense clusters of galaxies. In the decades since, generations of researchers have continued working toward Einstein’s dream. Renowned physicists Leonard Susskind and Jim Gates, and prominent historian Peter Galison discussed what’s been achieved and tackle pivotal questions. Would a unified theory reveal why there is a universe at all? Would it tell us why mathematics is adept at unraveling nature’s mysteries? Might it imply we are one universe of many, and what would that mean for our sense of how we fit into the cosmos? Moderated by Nobel Laureate Paul Nurse. This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

USENIX Enigma 2016 - Keys Under Doormats: Mandating Insecurity...
 
21:37
Ronald Rivest, Massachusetts Institute of Technology Twenty years ago, law enforcement organizations lobbied to require data and communication services to engineer their products to guarantee law enforcement access to all data. After lengthy debate and vigorous predictions of enforcement channels “going dark,” these attempts to regulate the emerging Internet were abandoned. In the intervening years, innovation on the Internet flourished, and law enforcement agencies found new and more effective means of accessing vastly larger quantities of data. Today we are again hearing calls for regulation to mandate the provision of exceptional access mechanisms. In this report, a group of computer scientists and security experts, many of whom participated in a 1997 study of these same topics, has convened to explore the likely effects of imposing extraordinary access mandates. We have found that the damage that could be caused by law enforcement exceptional access requirements would be even greater today than it would have been 20 years ago. In the wake of the growing economic and social cost of the fundamental insecurity of today’s Internet environment, any proposals that alter the security dynamics online should be approached with caution. Exceptional access would force Internet system developers to reverse “forward secrecy” design practices that seek to minimize the impact on user privacy when systems are breached. The complexity of today’s Internet environment, with millions of apps and globally connected services, means that new law enforcement requirements are likely to introduce unanticipated, hard to detect security flaws. Beyond these and other technical vulnerabilities, the prospect of globally deployed exceptional access systems raises difficult problems about how such an environment would be governed and how to ensure that such systems would respect human rights and the rule of law.

David A. McGrew, Scalable Efficient Cryptography for Multiple Security Services (July 29, 2004)
 
51:51
From the CISR video library (http://www.cisr.us) David A. McGrew, Cisco Systems Scalable Efficient Cryptography for Multiple Security Services July 29, 2004 at the Naval Postgraduate School (http://www.nps.edu) ABSTRACT The Galois/Counter Mode (GCM) of operation for block ciphers is secure and highly efficient, and can scale to very high data rates. It provides both encryption and message authentication, using universal hashing based on multiplication in the finite field GF(2128). GCM has several features that make it easy to use. It provides multiple security services with a single key, can accept nonces of arbitrary length, can act as a stand-alone message authentication code (MAC), and can be used as an incremental MAC. We will show how application designers using GCM can benefit from these features by providing example uses, including the important case of remote storage authentication. About David A. McGrew, Ph.D.: David works at Cisco Systems where he manages the Advanced Security Development group. His main interest is building practical security systems using cryptography with an emphasis on performance, scalability and deployability. His theoretical interests include cryptanalysis, the design of symmetric ciphers and message authentication codes, and information theory. At Cisco, he researches and develops secure protocols and systems, and represents security issues on the University Research Board. He also co-chairs the IRTF Crypto Forum Research Group and is a member of the International Association for Cryptologic Research and the Internet Society. David is an alumnus of The Ohio State University (B.S, Physics) and Michigan State University (Ph.D., Theoretical Nuclear Physics).

DEF CON 25 - Octane - Untrustworthy Hardware and How to Fix It
 
19:11
Modern computing platforms offer more freedom than ever before. The rise of Free and Open Source Software has led to more secure and heavily scrutinized cryptographic solutions. However, below the surface of open source operating systems, strictly closed source firmware along with device driver blobs and closed system architecture prevent users from examining, understanding, and trusting the systems where they run their private computations. Embedded technologies like Intel Management Engine pose significant threats when, not if, they get exploited. Advanced attackers in possession of firmware signing keys, and even potential access to chip fabrication, could wreak untold havoc on cryptographic devices we rely on. After surveying all-too-possible low level attacks on critical systems, we will introduce an alternative open source solution to peace-of-mind cryptography and private computing. By using programmable logic chips, called Field Programmable Gate Arrays, this device is more open source than any common personal computing system to date. No blobs, no hidden firmware features, and no secret closed source processors. This concept isn't "unhacakable", rather we believe it to be the most fixable; this is what users and hackers should ultimately be fighting for.

From Cypherpunk to Blockchains
 
28:57
Vinay Gupta (from Ethereum Foundation) talking about the history of cryptography. A cypherpunk is any activist advocating widespread use of strong cryptography and privacy-enhancing technologies as a route to social and political change. Originally communicating through the Cypherpunks electronic mailing list, informal groups aimed to achieve privacy and security through proactive use of cryptography. Cypherpunks have been engaged in an active movement since the late 1980s. Bitcoin was a summary of cryptography up until that point.

HD version - Telecomix Crypto Munitions Bureau
 
07:35
Hello. This is Cameron from Telecomix. Telecomix crypto munitions bureau works for the benefit of cipherspace. Cipherspace is the state of crypto anarchy. This means that your identity is anonymous as long as you stay protected. There are no identities or authorities in cipherspace, and it is not possible to enforce laws where there is no identity, or where there are no authorities. Today there are several threats to the inhabitants of the internet. The politicians of oppressive regimes in the east and in the west, in north and south, are imposing surveillance. Surveillance of the entire networks. What people say to each other, what information is transmitted between bots and humans alike. This aggression must be met with the strongest encryption algorithms availible to modern computers. With onion and garlic routing it is possible to erect the fractal cipherspace. With distributed hash tables it is possible to create networks that has no central node. There is no one that controls the fractal cipherspace. Internet as we know it, turns into darknet. Telecomix Crypto Munitions Bureau recommends that you use the following software: i2p, for anonymous and secure communications. Gnu Privacy Guard, for direct and verified communication. The onion router, TOR, to access the internets. It is either the Riemann sphere, the complex plane, as the number of 12 deadly missile strikes in Pakistan in january, of which 10 killing 123 civilians. Two drone strikes killed three al-qaeda leaders. Telecomix Munitions is a defense bureau. You can change the future of the internets by joining us in defending the networks and creating cipherspace. You can help defending yourself and your friends, yes, all inhabitants of the networks. By learning a few skills you can take control over technology. Telecomix munitions are currently developing and promoting advanced security devices, which can endure even the harshest forms of government or corporation surveillance. Your personal computer is an encryption device. Modern hardware can transform plain text to ciphertext with ease. So rapidly you barely notice the difference between unencrypted and encrypted data. The laws of mathematics are infinitely stronger than the laws of nations and corporations, as the human laws are really only ink on paper. The laws of mathematics, on the other hand, are the laws that define our very universe. With the use of modern crypto algorithms we can use this fact to defend free speech and the integrity of both bots and humans. Information is nothing but numbers, numbers governed not by human laws, but by the laws of mathematics. Networks that utilize the power of cryptography already exist. It will not be possible to stop the spread of the fractal cipherspace. Among the tools that are being researched at the Telecomix Crypto Munitions Bureau is the dropbox. Dropboxes are small computers, easily hidden, that can be moved to secure locations inside the strongholds of the corporations. The dropbox, once hidden, connects to the I2P or TOR network, and can then be used to transmit packets anonymously to any location at the internets. This is only one example of what you can do to enforce cipherspace. To find out more, come to telecomix.org or visit us in cipherspace on telecomix.i2p.
DEF CON 25 Crypto and Privacy Village - Mark Mager - Cryptanalysis in the Time of Ransomware
 
41:33
Crypto has served an important role in securing sensitive data throughout the years, but ransomware has flipped this script on its head by leveraging crypto as a means to instead prevent users from accessing their own data. The crypto seen in ransomware covers a wide range of complexity of symmetric and asymmetric algorithms, but flaws in their implementation and key storage / transmission routines have left the door open for users to retrieve their data in certain cases. In this talk, I'll provide a glimpse into some of the more notable ransomware crypto implementations that have surfaced over the past few years and how their weaknesses were exploited by security researchers through reverse engineering and cryptanalysis.
