In this paper, we develop a general theory of fixed point combinators, in higher-order logic equipped with Hilbert’s epsilon operator. This combinator allows for a direct and e...
Abstract. We investigate streaming evaluation of filters on XML documents, evaluated both at the root node and at an arbitrary node. Motivated by applications in protocol processin...
We analyze the multi-party contract-signing protocols of Garay and MacKenzie (GM) and of Baum and Waidner (BW). We use a finite-state tool, MOCHA, which allows specification of pr...
Today, security is recognized as an absolute need in application development. Programming environments offer mechanisms and concepts allowing an easy integration of security mecha...
In this paper we present a complete method for verifying properties expressed in the temporal logic CTL. In contrast to the majority of verification methods presented in recent yea...
