This paper contains techniques for enhancing the strength of any cryptographic hash function. For an "ideal", traditional hash function with an m-bit result, the complex...
We present the first simple power analysis (SPA) of software implementations of KeeLoq. Our attack drastically reduces the efforts required for a complete break of remote keyless...

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...
Media hashing is an alternative to achieve many applications previously accomplished with watermarking. The major disadvantage of the existing media hashing technologies is their ...
