Abstract. In this paper, we fully break the Algebraic Surface Cryptosystem (ASC for short) proposed at PKC’2009 [3]. This system is based on an unusual problem in multivariate cr...
Abstract. A5/1 pseudo-random bit generator, known from GSM networks, potentially might be used for different purposes, such as secret hiding during cryptographic hardware testing, ...

This work presents a cryptographic analysis of AN.ON’s anonymization protocols. We have discovered three flaws of differing severity. The first is caused by the fact that the ...
