Provably Secure Authenticated Tree Based Group Key Agreement Protocol

Ratna Dutta, Rana Barua, and Palash Sarkar

Abstract

We present a provably secure authenticated tree based key agreement protocol. The protocol is obtained by combining Boldyreva's multi-signature with an unauthenticated ternary tree based multi-party extension of Joux's key agreement protocol. The securiry is in the standard model as formalized by Bresson et al. The proof is based on the techniques used by Katz and Yung in proving the security of their key agreement protocol.
