Abstract. The little theories method, in which mathematical reasoning is distributed across a network of theories, is a powerful technique for describing and analyzing complex syst...
We continue investigation of languages, accepted by timed automata of Alur and Dill. In [ACM97] timed regular expressions equivalent to timed automata were introduced. Here we intr...
We have developed a general denition of segregation in the context of Z system specications. This denition is general enough to allow multi-way communications between otherwise seg...
We construct an efficient identity based encryption system based on the standard learning with errors (LWE) problem. Our security proof holds in the standard model. The key step in...
This paper describes ProSQL, a novel prototyping tool to support the development of extensions to SQL. ProSQL provides a simple way to prototype the features of a proposed extensio...
