Distinguishing Stream Ciphers with Convolutional Filters
Joan Daemen and Gilles Van Assche
Abstract: This paper presents a new type of distinguisher for the shrinking generator and the alternating-step generator with known feedback polynomial and for the multiplexor generator. For the former the distinguisher is more efficient than existing ones and for the latter it results in a complete breakdown of security. The distinguisher is conceptually very simple and lends itself to theoretical analysis leading to reliable predictions of its probability of success.
