Process Algebrai Frameworks for the Specification and Analysis of Cryptographic Protocols
by Roberto Gorrieri and Fabio Martinelli

Abstract:

Two process algebraic approaches for the analysis of cryptographic
protocols, namely the spi calculus by Abadi and Gordon and CryptoSPA
by Focardi, Gorrieri and Martinelli, are surveyed and compared.
We show that the two process algebras have comparable expressive power,
by providing an encoding of the former into the latter.
We also discuss the relationships among some security properties, i.e.,
authenticity and secrecy, that have different definitions in the
two approaches.
