Secrecy in Untrusted Networks

Bugliesi, M., Crafa, S., Prelic, A. and Sassone, V. (2003) Secrecy in Untrusted Networks At 30th International Colloquium on Automata, Languages and Programming, ICALP 2003.. , pp. 969-983.

Record type: Conference or Workshop Item (Paper)

Abstract

We investigate the protection of migrating agents against the untrusted sites they traverse. The resulting calculus provides a formal framework to reason about protection policies and security protocols over distributed, mobile infrastructures, and aims to stand to ambients as the spi calculus stands to ?. We present a type system that separates trusted and untrusted data and code, while allowing safe interactions with untrusted sites. We prove that the type system enforces a privacy property, and show the expressiveness of the calculus via examples and an encoding of the spi calculus.
