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.
