With chosen-IV chosen texts, David Wagner has analyzed the multiple modes of operation proposed by Eli Biham in FSE’98. However, his method is too unrealistic. We use only known-...
We add an operation of group creation to the typed π-calculus, where a group is a type for channels. Creation of fresh groups has the effect of statically preventing certain com...
