  1. FORMAL METHODS IN CRYPTOGRAPHIC PROTOCOL ANALYSIS: EMERGING ISSUES AND TRENDS Catherine Meadows Center for High Assurance Computer Systems Naval Research Laboratory Washington, DC 20375 meadows@itd.nrl.navy.mil

  2. Emerging Properties of Protocols • Greater interoperation • Meta protocols to negotiate agreement upon protocols, eg. ISAKMP-IKE • Negotiation of policy • Security associations • Certificate hierarchies • Greater complexity • Especially for electronic commerce • Group-oriented protocols • Emerging security threats • Denial of service • Traffic analysis

  3. ISSUES AND OPEN PROBLEMS • Composability • Incremental Analysis • Probabalistic and Game-Theoretic Analysis • High Fidelity • Open-Ended and Group Protocols • Transaction Processing • Getting it into the Real World
