Abstract. Vx86 is the first static analyzer for sequential Intel x86 assembler code using automated deductive verification. It proves the correctness of assembler code against func...
Abstract. In this article we introduce redundant trinomials to represent elements of finite fields of characteristic 2. This paper develops applications to cryptography, especial...
