This paper shows that Py and Pypy are practically insecure. If one key is used with about 216 IVs with special differences, with high probability two identical keystreams will appe...

Let us have an NLFSR with the feedback function g(x) and an LFSR with the generating polynomial f(x). The function g(x) is a Boolean function on the state of the NLFSR and the LFS...

DECIM is a hardware oriented stream cipher with an 80-bit key and a 64-bit IV. In this paper, we point out two serious flaws in DECIM. One flaw is in the initialization of DECIM. I...

Although many strong cryptanalytic tools exploit weaknesses in the data-randomizinig part of a block cipher, relatively few general tools for cryptanalyzing on the other part, the ...
