—In this paper we consider the problem of verifying time–sensitive security protocols, where temporal aspects explicitly appear in the description. In previous work, we proposed Timed HLPSL, an extension of the specification language HLPSL (originally developed in the Avispa Project), where quantitative temporal aspects of security protocols can be specified. In this work, a model checking tool, TPMC, for the analysis of security protocols is presented, which employs THLPSL as a specification language and UPPAAL as the model checking engine. To illustrate the tool, we provide a specification of the Wide Mouthed Frog protocol in THLPSL, and report some experimental results on a number of timed and untimed security protocols.
