In this paper we formalize the notion of a ring signature, which makes it possible to specify a set of possible signers without revealing which member actually produced the signatu...
Abstract. We present a new algorithm for upper bounding the maximum average linear hull probability for SPNs, a value required to determine provable security against linear cryptan...
Abstract. Modes of operation adapt block ciphers to many applications. Among the encryption modes, only CFB Cipher Feedback has both of the following properties: Firstly it allow...

At ISW’99, Nishioka, Hanaoka and Imai proposed a digital signature scheme on ID-based key-sharing infrastructures. That signature scheme is claimed to be secure if the discrete l...
Of the five AES finalists four—MARS, RC6, Rijndael, Twofish— have not only (expected) good security but also exceptional performance on the PC platforms, especially on those...
