Abstract. The banking industry in Norway has developed a new security infrastructure for conducting commerce on the Internet. The initiative, called BankID, aims to become a nation...
We propose the notion of rewriting modules in order to provide a structural and hierarchical approach of TRS. We define then relative dependency pairs built upon these modules whic...
The combination of two security protocols, a simple shared-key communication protocol and the Di e-Hellman key distribution protocol, is modeled formally and proved correct. The m...
We present a compositional semantics of synchronous systems that captures both safety and progress properties of such systems. The fair synchronous transitions systems (fsts) mode...
