A Time-Memory Tradeoff Attack Against LILI-128
Abstract
In this note we discuss a novel but 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 $2^{46}$ bits of keystream, a lookup table of $2^{45}$ 89-bit words and computational effort which is roughly equivalent to $2^{48}$ DES operations.
