摘要
We present a provably secure authenticated tree based key agreement protocol. The protocol is obtained by combining Boldyreva's multi-signature with Barua et al.'s unauthenticated ternary tree based multi-party extension of Joux's key agreement protocol. The security 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.
