Fast correlation attack on stream cipher ABC v3
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...

Weak Keys for IDEA
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...

Weak Key Analysis and Micro-controller Implementation of CA Stream Ciphers
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...
