ABC v3 is a stream cipher proposed as a candidate to ECRYPT Estream Project which enters the second evaluation phase. Its key length is 128 bits. In this paper, We show that, ther...
The reflection attack is a recently discovered self similarity analysis which is usually mounted on ciphers with many fixed points. In this paper, we describe two reflection attack...
Large classes of weak keys have been found for the block cipher algorithm IDEA, previously known as IPES [2]. IDEA has a 128bit key and encrypts blocks of 64 bits. For a class of 2...
Abstract. Inthis paper we present several weaknesses in the keyscheduling algorithm of RC4, and describe their cryptanalytic signi cance. We identify a large number of weak keys, i...
Abstract. In the paper we extend known results studying the application of CAs for stream ciphers. We illustrate the notion of weak keys in such a cryptosystem and describe the exp...
