We add an operation of group creation to the typed pi-calculus, where a group is a type for channels. Creation of fresh groups has the effect of statically preventing certain communications, and can block the accidental or malicious leakage of secrets.

Secrecy and group creation

Abstract

We add an operation of group creation to the typed pi-calculus, where a group is a type for channels. Creation of fresh groups has the effect of statically preventing certain communications, and can block the accidental or malicious leakage of secrets. We adapt a notion of secrecy introduced by Abadi, and prove a preservation of secrecy property. When applied to the ambient calculus, the same notion of group creation can be used to create and preserve shared secrets among mobile agents. © Elsevier Ltd.
