Abstract:

We discuss a novel and simple time-memory tradeoff attack against the stream cipher LILI-128. The attack defeats the security advantage of having an irregular stepping function. The attack requires  bits of keystream, a lookup table of 89-bit words and computational effort which is roughly equivalent to DES operations.
