Cryptanalysis of White-Box DES Implementations with Arbitrary External Encodings,te-box attack context. In such a context, an attacker has full access to the implementation and its execution environment. In order to provide an extra level of security, an implementation shielded with external encodings was introduced by Chow . and improved by Link and Neumann?[10]. In this paper,

Cryptanalysis of White Box DES Implementations, algorithm should be kept public while the whole security should rely on the secrecy of the key. In some contexts, source codes are publicly available, while the key should be kept secret; this is the challenge of code obfuscation. This paper deals with the cryptanalysis of such methods of obfuscati

Attacks on the ESA-PSS-04-151 MAC Scheme, show that in spite of the very large key length of 2940 bits there are (under certain circumstances) feasible known message attacks. In particular, we show that an attacker who is given about .?≈80-100 message/MAC pairs and 60 special bits of the key can forge the MAC of any further message with hi

Two Trivial Attacks on ,,longer 128-bit keys..Finally, we identify interesting open problems and propose a new design ., which resists all of our attacks proposed in this paper. It also accepts a 128 bit secret key due to the improved security level.
