Module19 – Cryptography, Section 19.4 – Cryptographic protocol. Cryptographic protocol applies cryptographic methods and describes how the algorithms should be used and some aspects are: – Key agreement or establishment – Entity authentication – Symmetric encryption and message authentication material construction – Secured application-level data transport – Non-repudiation methods – Secret sharing methods – Secure multi-party computation Crypto Protocols • Internet Key Exchange (IKE) • IPSec (Internet Protocol Security) • Kerberos • Off-the-Record Messaging (OTR) • Point to Point Protocol (PPP) • Signal Protocol • Transport Layer Security (TLS) • ZRTP (Z and Real-time Transport Protocol) TLS is a cryptographic protocol that is used to secure web (HTTP/HTTPS) connections. TLS is used in applications such as web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP). The 3 aspects of TLS are: • It has an entity authentication mechanism, based on the X.509 system. • A key setup phase, where a symmetric encryption key is formed by employing public-key cryptography. • An application-level data transport function. Cryptographic protocols can be verified formally to identify threats and done through below models: • Dolev–Yao model • Burrows–Abadi–Needham logic (BAN logic) • Protocol composition logic (PCL) • Strand space • Alice & Bob notation Projects and tools for Security protocol verification – AVISPA and AVANTSSAR – Casper / FDR compiler – CryptoVerif, ProVerif – Cryptographic Protocol Shapes Analyzer (CPSA) – Knowledge In Security protocolS (KISS) – Maude-NRL Protocol Analyzer (Maude-NPA) – Scyther – Tamarin Prover

Telegram is a popular instant messaging service, a self-described fast and secure solution. It introduces its own home-made cryptographic protocol MTProto instead of using already known solutions, which was criticised by a significant part of the cryptographic community. In this talk we will briefly introduce the protocol to provide context to the reader and then present two major findings we discovered as part of our security analysis performed in late 2016. First, the undocumented obfuscation method Telegram uses, and second, a replay attack vulnerability we discovered. The analysis was mainly focused on the MTProto protocol and the Telegram's official client for Android.

Learn how quantum communication provides security that is guaranteed by the laws of nature. Take this course free on edX: https://www.edx.org/course/quantum-cryptography-caltechx-delftx-qucryptox#! ABOUT THIS COURSE How can you tell a secret when everyone is able to listen in? In this course, you will learn how to use quantum effects, such as quantum entanglement and uncertainty, to implement cryptographic tasks with levels of security that are impossible to achieve classically. This interdisciplinary course is an introduction to the exciting field of quantum cryptography, developed in collaboration between QuTech at Delft University of Technology and the California Institute of Technology. By the end of the course you will: - Be armed with a fundamental toolbox for understanding, designing and analyzing quantum protocols. - Understand quantum key distribution protocols. - Understand how untrusted quantum devices can be tested. - Be familiar with modern quantum cryptography – beyond quantum key distribution. This course assumes a solid knowledge of linear algebra and probability at the level of an advanced undergraduate. Basic knowledge of elementary quantum information (qubits and simple measurements) is also assumed, but if you are completely new to quantum information additional videos are provided for you to fill in any gaps. WHAT YOU'LL LEARN - Fundamental ideas of quantum cryptography - Cryptographic concepts and tools: security definitions, the min-entropy, privacy amplification - Protocols and proofs of security for quantum key distribution - The basics of device-independent quantum cryptography - Modern quantum cryptographic tasks and protocols

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. NOTE 2: The following video explains BB84 as well, and gives more detail regarding the physics details: http://www.youtube.com/watch?v=7SMcf1MdOaQ NOTE 3: Here is another very interesting video about quantum cryptography. Any given real-world implementation, despite using the BB84 protocol, is bound to expose weaknesses that can be exploited. For example: http://www.youtube.com/watch?v=T0WnUlF2eAo

Saturday, July 22, 2006: 7:00 pm (Area "B"): This lecture will show how to construct advanced cryptographic protocols. Beginning with a set of requirements for a communications protocol that includes immunity from replay attacks, traffic analysis resistance, and resiliency against partial compromise, the audience will be shown how a naive protocol can be iteratively improved into a protocol satisfying those requirements.

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.

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.

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.
