Constant Round Authenticated Group Key Agreement via Distributed Computation
Abstract. A group key agreement protocol allows a set of users, communicating over a public network, to agree on a private session key. Most of the schemes proposed so far require ...

Separable and Anonymous Identity-Based Key Issuing
Abstract. In identity-based (ID-based) cryptosystems, a local registration authority (LRA) is responsible for authentication of users while the key generation center (KGC) is respo...

Dynamic Group Key Agreement in Tree-Based Setting
We present a provably secure tree based authenticated group key agreement protocol in dynamic scenario. Bilinear pairing and multi-signature are at the heart of our protocol. We p...

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 ...
