Abstract. The cipher family SPEED (and an associated hashing mode) was recently proposed in Financial Cryptography '97. This paper cryptanalyzes that proposal, in two parts: F...

In this paper we describe our new CS2 block cipher which is an extension of the original CS-Cipher. Our new design inherits the efficiency of the original design while being upgrad...
We describe a secure transformation of stateful connections or parts of them into stateless ones by attaching the state information to the messages. Secret-key cryptography is used...
We introduce a linear algebraic model of computation, the Span Program, and prove several upper and lower bounds on it. These results yield the following applications in complexit...
Abstract. Lattice basis reduction is an important problem in geometry of numbers with applications in combinatorial optimization, computer algebra, and cryptography. The well-known...
