Gorrieri and Martinelli's tGNDC is a general framework for the formal verification of security protocols in a concurrent scenario. We generalise their tGNDC schema to verify wireless network security protocols. Our generalisation relies on a simple timed broadcasting process calculus whose operational semantics is given in terms of a labelled transition system which is used to derive a standard simulation theory. We apply our tGNDC schema to perform a security analysis of LiSP, a well-known key management protocol for wireless sensor networks.
