Modeling leakage of ephemeral secrets in tripartite/group key exchange
Recent advances in the design and analysis of secure two-party key exchange (2KE) such as the leakage of ephemeral secrets used during the attacked sessions remained unnoticed by the current models for group key exchange ...
Security arguments for the UM key agreement protocol in the NIST SP 800-56A standard
(ACM Press, 2008)
The Unified Model (UM) key agreement protocol is an efficient Diffie-Hellman scheme that has been included in many cryptographic standards, most recently in the NIST SP 800-56A standard. The UM protocol is believed to ...
Strongly secure authenticated key exchange without NAXOS' approach
LaMacchia, Lauter and Mityagin  proposed the extended Canetti-Krawczyk (eCK) model and an AKE protocol, called NAXOS. Unlike previous security models, the adversary in the eCK model is allowed to obtain ephemeral secret ...
