Abstract. We investigate combinatorial commutation properties for reordering a sequence of two kinds of steps, and for separating wellfoundedness of unions of relations. To that en...
Abstract. We give an overview of Agda, the latest in a series of dependently typed programming languages developed in Gothenburg. Agda is based on Martin-L¨of’s intuitionistic t...
Abstract. We give an optimal (exptime), sound and complete tableaubased algorithm for deciding satisfiability with respect to a TBox in the logic ALCI using global state caching. ...
Abstract. This paper presents a critical analysis of the AACS drivehost authentication scheme. A few weaknesses are identified which could lead to various attacks on the scheme. I...
Abstract. Here we study a weakness of the RC4 Key Scheduling Algorithm (KSA) that has already been noted by Mantin and Mironov. Consider the RC4 permutation S of N (usually 256) by...
