A Python implementation of the Berlekamp-Massey algorithm, for finding the minimal LFSR that generates a given sequence, in lfsr.py How to use You can use the Galois LFSR implementation anywhere where you would need a LFSR implementation. If performance is critical, I suggest you find more effi...
We present simple and efficient hash functions applicable to secure authentication of information. The constructions are mainly intended for message authentication in systems implementing stream cipher encryption and are suitable for other applications as well. The proposed hash functions are implemented throu...
With only short ciphertexts, it is shown how to completely recover the different feedback polynomials and the combining function, when the algorithm is totally unknown. Estimates of necessary cipherlength and experimental results are detailed.
