This document describes the results of the security evaluation of the communications system. The evaluation considers communications between the SPD, the STG, the SP node, and the RA node, with respect to threats such as eavesdropping, masquerading, message tampering, and replay attacks. The method of evaluation is to systematically compare a precise description of the communications with the actual messages exchanged in the implementation. The message contents is extracted via network analysis tools applied to a running PCAS instance.
