Flow logic for Dolev-Yao secrecy in cryptographic processes

Abstract
En 中文
We introduce the vspi-calculus that strengthens the notion of perfect symmetric cryptography of the spi-calculus by making encryption history dependent. We give our calculus an operational and a static semantics. The latter is a control flow analysis (CFA), defined in the form of a flow logic, and it is proved semantically correct. We then apply our CFA to check security properties; in particular, we show that secrecy A la Dolev-Yao can be expressed in terms of the CFA. (C) 2002 Elsevier Science B.V. All rights reserved.
