Rijndael is the new Advanced Encryption Standard designed by V. Rijmen and J. Daemen and chosen as AES by the NIST in October 2000. Surprisingly, the number of cryptanalyses agains...
Abstract. One of the central lines of cryptographic research is identifying the weakest assumptions required for the construction of secure primitives. In the context of group sign...
Abstract. A group key agreement protocol allows a set of users, communicating over a public network, to agree on a private session key. Most of the schemes proposed so far require ...
In implementing cryptographic algorithms on limited devices such as smart cards, speed and memory optimization had always been a challenge. With the advent of side channel attacks,...
This paper provides a comprehensive treatment of forward-security in the context of sharedkey based cryptographic primitives, as a practical means to mitigate the damage caused by...
