Abstract. The recent algebraic attacks have received a lot of attention in cryptographic literature. The algebraic immunity of a Boolean function quantifies its resistance to the s...
In this paper we analyze the block cipher SAFER K. First, we show a weakness in the key schedule, that has the effect that for almost every key there exists on the average three an...
Twofish is a new block cipher with a 128 bit block, and a key length of 128, 192, or 256 bits, which has been submitted as an AES candidate. In this paper, we briefly review the st...

The Advanced Encryption Standard (AES) is the Federal Information Processing Standard for symmetric encryption. It is widely believed to be secure and efficient, and is therefore b...
We investigate the all-or-nothing encryption paradigm which was introduced by Rivest as a new mode of operation for block ciphers. The paradigm involves composing an all-or-nothing...
