Fast Software Encryption 2015IACR logo



Welcome to the home page of the 22nd International Workshop on Fast Software Encryption. FSE 2015 is organized by the IACR - International Association for Cryptologic Research, was held in İstanbul between the 8th and the 11th of March, 2015.


FSE is one of the IACR flagship annual events, and concentrates on fast and secure primitives for symmetric cryptography, including the design and analysis of block ciphers, stream ciphers, encryption schemes, analysis and evaluation tools, hash functions, MAC and authenticated encryption algorithms.

 Challenges in Lightweight Crypto Standardization

 There are several emerging areas in which highly constrained devices are interconnected, typically communicating wirelessly with one another, working in concert to accomplish some task. Examples of these areas include: sensor networks, healthcare, distributed control systems, the internet of things, cyber-physical systems, and the smart grid. Security and privacy are important in all of these areas. However, modern cryptographic algorithms (such as AES) are not always practical for devices used in these applications, due to various limitations. When these algorithms can be engineered to fit into the limited resources of constrained environments, their performance is typically not acceptable. Hence, new dedicated cryptographic solutions are needed. The talk includes an overview of standardization attempts for lightweight cryptography, the challenges of standardization for lightweight cryptography and NIST's plan for exploring potential standardization of lightweight primitives.

 Conflicting roles: the NSA and cryptography


Abstract: The NSA's conflicting role of defensive and offensive roles with regard to cryptography is not very well understood. Recent work to undercover more of these details has shown both unsurprising and surprising results. There is much work to be done - a discussion with the broader cryptographic and reverse engineering community is the next major step.
