A cryptographic protocol is a protocol executed by several distant agents through a network where the messages or part of the messages are produced using cryptographic functions (encryption, hashing, etc.). Cryptographic protocols are used for various purpose between the agents:. May 7, 2006 - This is regarded as offensive because of the malicious payload normally embedded in the virus, and because of the use of anti-anti-virus techniques For instance, on networks some layer 2 protocols are based on crypto (WEP, WPA/TKIP, and others), as are some upper layer protocols (IPSec, SSH, SSL, primitives such as commutative encryption. We give a list of some relevant al- gebraic properties of cryptographic operators, and for each of them, we provide examples of protocols or attacks using these properties. We also give an overview of the existing methods in formal approaches for analyzing cryptographic proto-. Using cryptographic techniques, it may be possible to allow intermediate results in a distributed algorithm to be certified independently of who provides them, reducing themes of complexity theory, e.g., interactive provability, average vs. worst-case complexity, and the inherent communication costs of multiparty protocols. Web is an electronic protocol which allows people to communicate mail, information, and commerce through a digital medium. This new method of information exchange has caused a tremendous need for information security. A thorough understanding of cryptography and encryption will help people develop better ways to etc. The analysis techniques discussed in this survey assume per- fect cryptography. This means that cryptographic primitives are considered as black boxes satisfying certain properties, as described in section 2.1. below.

Cryptography: Crash Course Computer Science #33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

Symmetric Key and Public Key Encryption
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

The BB84 Protocol
A short video attempting to explain the Bennett & Brassard quantum cryptography protocol. I've omitted any mention of the particular details of quantum physics that would be involved in actual real-world implementations, such as particle polarization axes, spin, and so forth, instead replacing them with abstract "processes" and freakish mysterious "machines". The physical details (interesting though they are) are not needed to understand the basics of the protocol, and I'm no physicist, so I'd probably mess them up if I tried (assuming I haven't already!). Making these images has increased my affection for Microsoft PowerPoint, and putting them all into a video has hugely exacerbated my hatred for Windows Movie Maker. NOTE: An important missing piece of information: When Alice sends qubits to Bob, she chooses between process A and process B randomly for each qubit.

PCI Requirement 4.1 – Use Strong Cryptography & Security Protocols to Safeguard Sensitive CHD
Learn more at https://kirkpatrickprice.com/video/pci-requirement-4-1-use-strong-cryptography-security-protocols-safeguard-sensitive-chd-transmission/ If your organization transmits sensitive cardholder data over an open or public network, that data must be encrypted using strong cryptography and security protocols, according to PCI Requirement 4.1. Examples of open, public networks include the Internet, Bluetooth, cell phones/GSM, wireless Internet, etc. The purpose of this requirement is to prevent attackers from obtaining data while in transit, which is a common practice. Best practices for safeguarding sensitive cardholder data during transmission include: • Only use trusted keys and certificates associated with the encryption. If a certificate has expired or is not issued by a trusted source, do not accept it. • Any security protocols in use should only support secure versions or configurations; if not, the known vulnerabilities of a protocol could be exploited by an attacker. This also prevents an insecure connection. Any connection that could result in an insecure connection cannot be accepted. An example of an insecure protocol is WEP, which cannot be used for security. • The encryption strength is appropriate for the encryption methodology in use. • Documentation should define all places where cardholder data is transmitted or received over open, public networks. • Documentation should outline a process for acceptance of trusted keys and certificates, how the implemented security protocols only support secure versions or configurations, and why the encryption strength is appropriate.

One of the more elegant and counterintuitive ideas in modern cryptography is the notion of a zero-knowledge proof (ZNP). A ZNP allows one party (the prover) to prove to another (the verifier) that they know a secret without revealing any information about the secret itself.It’s a totally wild idea that has deep implications for online security.

Charm: A Framework for Rapidly Prototyping Cryptosystems
Over the past decade the cryptographic research community has made impressive progress in developing new cryptographic protocols. This work has advanced our understanding of basic technologies such as public key encryption, key agreement, and digital signatures. Moreover, it has given us entirely new paradigms for securing data, such as Attribute Based Encryption, anonymous credentials and techniques for computing on encrypted data. Despite these advances, only a trickle of new cryptographic technology has filtered down to the systems community in the form of useable cryptographic implementations. Even supported prototype research implementations are few and far between. This is a major loss for researchers, to say nothing of industry and the open source community. In this talk we introduce Charm, an extensible Python-based framework for rapidly prototyping cryptographic systems. Charm was designed from the ground up to support the development of advanced cryptographic schemes. It includes support for multiple cryptographic settings, an extensive library of re-usable code, along with the infrastructure necessary to quickly implement interactive protocols. Our framework also provides a series of specialized tools that enable different cryptosystems to interoperate. This paper describes Charm and the various capabilities provided through our modular architecture. Through several examples, we show that our approach produces a potential order of magnitude decrease in code size compared to standard C implementations, while inducing an acceptable performance impact.

Cryptographic Protocols By Sunil Chebolu, Undergraduate Colloquium in Mathematics ISU, Part-1
How is your credit card information on Amazon protected? How can you convince someone that you have solved a Sudoku puzzle without showing them your solution? How can you toss a coin with a friend who lives in a different city on the telephone? How can you find out if you got a better grade than your friend on the final without revealing your grade or finding their grade? Answers to such intriguing and ostensibly unsolvable problems have been solved by mathematicians using clever protocols. In this talk some of these protocols and the mathematics behind them are discussed.
