Security analysis of the variant of the self-shrinking generator proposed at ICISC 2006
Dong Hoon Lee and Je Hong Park and Jaewoo Han
Abstract: In this paper, we revisit the variant of the self-shrinking
generator(SSG) proposed by Chang et al. at ICISC 2006. This variant,
which we call SSG-XOR was claimed to have better cryptographic
properties than SSG in a practical setting. But we show that SSG-XOR
has no advantage over SSG from the viewpoint of practical cryptanalysis.
