English Abstract: In this paper we utilize an algebraic method called the characteristic set method to attack Bivium and Trivium in the guess-and-determine way. Our attack focuses on recovering the internal states of these two ciphers. We theoretically analyze the performance of different guessing strategies in the guess-and-determine method and present a good one. We show a large amount of experimental results about these two problems with different parameters. From these experimental data we obtain the following results. For Bivium, with 177-bit keystream the expected attack time by the characteristic set method is about 231.81 seconds. And for Trivium, with 288-bit keystream the expected attack time is about 2114.27 seconds. © 2011 Springer-Verlag.
