Key Agreement Protocols and Their Security Analysis

This paper proposes new protocols for two goals: authenticated key agreement and authenticated key agreement with key con rmation in the asymmetric public-key setting. A formalmodel of distributed computing is provided, and a de nition of the goals within this model supplied. The protocols proposed are then proven correct within this framework in the random oracle model. We emphasize the relevance of these theoretical results to the security of systems used in practice. Practical implementation of the protocols is discussed. Such implementations are currently under consideration for standardization 2, 3, 21 .
