2002 Theoretical analysis of a correlation attack based on convolutional codes
abstract
One general class of attacks on stream ciphers is correlation attacks. Most of previous results regarding performance of correlation attacks have been based entirely on simulations. We use random coding bounds for convolutional codes to give a theoretical analysis of a previously proposed correlation attack based on convolutional codes. The results from the theoretical derivation are verified by simulations.

2002 On the complexity of some cryptographic problems based on the general decoding problem
abstract
A new probabilistic algorithm for decoding one received word from a set of many given received words, into a codeword such that the Hamming distance between the received word and the codeword is at most t, is proposed. The new algorithm is applicable to several cryptographic problems, such as the Stern (1989, 1994) identification scheme, the McEliece (1978) public-key cryptosystem, and in correlation attacks on stream ciphers. When applicable, it runs significantly faster than previous algorithms used for attacks on these cryptosystems.
