Cryptographic Schemes Based on the ASASA Structure: Black-box, White-box, and Public-key
Alex Biryukov and Charles Bouillaguet and Dmitry Khovratovich
Abstract
In this paper we pick up an old challenge to design public key or white-box constructions from symmetric cipher components. We design several encryption schemes based on the ASASA structure ranging from fast and generic symmetric ciphers to compact public key and white-box constructions based on generic affine transformations combined with specially designed low degree non-linear layers. While explaining our design process we show several instructive attacks on the weaker variants of our schemes.
