| 摘要: |
| 为保证开放网络环境下的安全通信，在现有基于身份密码体制的基础上，提出一种新的基于分层身份的网络密钥协商协议.新协议满足所有密钥协商的安全属性，计算效率全面领先目前已有协议，能够有效地解决传统公钥系统需要进行证书传递和验证的问题，且能满足大规模网络应用的需求. |

| Abstract: |
| To ensure the communication security in a public network, a hierarchical identity-based key agreement protocol based on the present identity-based cryptosystem is proposed in this paper. The new protocol which is able to solve the problem of the certification transfering and verifying in the traditional public key cryptosystem efficiently achieves all of the known security attributes and can be achieved in the state-of-art speed which can meet the demand of large scale network applications. |
