Sosemanuk is a new synchronous software-oriented stream cipher, corresponding to Profile 1 of the ECRYPT call for stream cipher primitives. Its key length is variable between 128 ...
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 revisit meet-in-the-middle attacks on block ciphers and recent developments in meet-in-the-middle preimage attacks on hash functions. Despite the presence of a secret key in the...
