Efficient, Authenticated, and Fault-Tolerant Key Agreement for Dynamic Peer Groups
We present an efficient authenticated and fault-tolerant protocol (AFTD) for tree-based key agreement. Our approach is driven by the insight that when a Diffie-Hellman blinded key ...

Low-Level Ideal Signatures and General Integrity Idealization
Abstract. Recently we showed how to justify a Dolev-Yao type model of cryptography as used in virtually all automated protocol provers under active attacks and in arbitrary protoco...
