Cryptographic Schemes Based on the ASASA Structure: Black-box, White-box, and Public-key

Alex Biryukov, Charles Bouillaguet, and Dmitry Khovratovich

Abstract

In this paper we pick up an old challenge to design public key or white-box construction from symmetric cipher components. We design several encryption schemes based on the \textsf{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.
