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...
Abstract. Many algorithmic problems, which are used to prove the security of a cryptographic system, are shown to be characterized as the subgroup membership problem. We then apply...
Abstract-- The performance of ad hoc networks depends on cooperation and trust among distributed nodes. To enhance security in ad hoc networks, it is important to evaluate trustwor...
Block ciphers are usually based on one top-level scheme into which we plug “round functions”. To analyze security, it is important to study the intrinsic security provided by t...
Recently the braid groups were introduced as a new source for cryptography. The group operations are performed efficiently and the features are quite different from those of other...
