Let g be an element of prime order p in an abelian group and let Zp. We show that if g, g , and gd are given for a positive divisor d of p - 1, the secret key can be computed de...
Abstract. Logics that involve collections (sets, multisets), and cardinality constraints are useful for reasoning about unbounded data structures and concurrent processes. To make ...
We present an automatic verification procedure based on RGSep that is suitable for reasoning about fine-grained concurrent heapmanipulating programs. The procedure computes a set o...
A natural encoding of synchronous message exchange with direct wait-control is proved to be equivalent in a distributed environment to a refinement which uses semaphores to implem...
Abstract. The aim of this paper is to gradually introduce formalism in the requirement engineering phase in order to facilitate its validation. We analyze and elicit our requiremen...
