Verifying Repli ation on a Distributed Shared Data Spa e with Time Stamps

Abstra t| We investigate transparent repli ation of omponents on top of the distributed data spa e ar hite ture Spli e. In Spli e ea h omponent has its own lo al data spa e whi h an be kept small using keys, time stamps and sele tive overwriting. Sin e Spli e appli ations are often safetyriti al, we use two omplementary formal tools to ensure orre tness: the CRL tool set is used for a rapid inv...

Simulation Logic, Applets and Compositional Verification

We present a ompositional veri ation method for ontrol ow based safety properties of smart ard applets. Our method rests on a lose orresponden e between transition system models ordered by simulation and Hennessy-Milner logi extended with simultaneous greatest xed points. We show that simulation an be hara terised logi ally and, vi e versa, logi al satisfa tion an be represented behaviourally b...
