Combining Message Authentication and Encryption  (presentation slides) A recent field of study is mechanisms for combining message authentication and encryption into one efficient primitive. Even if there are no efficiency gains to be made, there are practical and usability issues. This paper presents an overview of some recent work in this area.

A Precis of the New Attacks on GSM Encryption (September 2003)

Turing: A Fast Stream Cipher is a full paper about the final design of Turing. (Accepted to Fast Software Encryption 2003.)

Turing: A Fast Software Stream Cipher (240k) is the full presentation originally prepared for the rump session of Crypto2002 (27 slides, only 1 of which was shown). It's been updated to be consistent with the source code.

A Practical Cryptanalysis of SSC2 (presentation slides) was presented at SAC 2001.

Exploiting Multiples of the Connection Polynomial in Word-Oriented Stream Ciphers was presented at AsiaCrypt 2000.

Guess and Determine Attacks on SNOW (presentation slides) was presented at SAC 2002.

A Mode of Operation with Partial Encryption and Message Integrity (PEMI) is a paper describing and proving the method we proposed just after the NIST Modes of Operation workshop in 2001, which is sometimes referred to as "Hawkes-Rose Mode". The paper has never quite found the right conference for it.

Cryptographic Algorithms Revealed is a tutorial intended to give a somewhat technical and detailed explanation of how various cryptographic algorithms actually work. It has been presented at a number of conferences around the world.

Authentication and Security in Mobile Phones is a paper presented at the 1999 Australian Unix User's Group conference, which is an overview of the cryptographic mechanisms used in ANSI-41 and GSM systems, with some (now dated) glimpses into the future authentication and security procedures and algorithms. Authentication and Security in Wireless Phones is a more recently updated set of presentation slides.

A paper about ssmail was presented at the 1999 USENIX LISA conference. Here is ssmail: Opportunistic Encryption in Sendmail.

On the Applicability of Distinguishing Attacks Against Stream Ciphers We demonstrate that the existence of distinguishing attacks against stream ciphers is unrelated to their security in practical use, and in particular that the amount of data required to perform a distinguishing attack is unrelated to the key length of the cipher.
