| 英文摘要 | Multiparty key agreement (mka) is a secure and robust approach to establish a group key for secure group oriented applications over non-private underlying networks, and it can be efficiently implemented with ecc (elliptic curve cryptography). in this paper, we propose a generic two round model for ecc based mka. all users involved are organized into a ring in this model and distributedly compute a group key by two round message exchanges. upon this model, we construct a concrete ecc based mka protocol with scalability and low computational complexity. the protocol is dynamic, that is, it supports key update when user group membership changes to ensure forward secrecy and backward secrecy. the protocol :is proved to be secure under the decision diffie-hellman (ddh) assumption on the elliptic curve. its security is reduced to the intractable ddh problem on the elliptic curve. |
