A Hardware-Assisted Realtime Attack on A5/2 Without Precomputations
Abstract. A5/2 is a synchronous stream cipher that is used for protecting GSM communication. Recently, some powerful attacks [2,10] on A5/2 have been proposed. In this contribution...

Software-Hardware Trade-Offs: Application to A5/1 Cryptanalysis
This paper shows how a well-balanced trade-off between a generic workstation and dumb but fast reconfigurable hardware can lead to a more efficient implementation of a cryptanalysi...

Fast Computation of Large Distributions and Its Cryptographic Applications
Let X1, X2, . . . , Xk be independent n bit random variables. If they have arbitrary distributions, we show how to compute distributions like Pr{X1 ⊕ X2 ⊕ · · · ⊕ Xk} and ...
