摘　　要：公钥证书是公开密钥的重要载体。随着以AdHoc为代表的自组织网络、分布式网络的发展,需要安全的可对公钥证书的生成、发布、更新、验证、撤销等实现自治管理的自组织证书管理方案。论文提出了一种安全的证书自组织管理方案,该方案利用单向哈希链,实现了无在线可信第三方的证书自组织管理。该方案的安全性同时依赖于节点私钥与单项哈希链的安全,具有更好的安全特性。Public key certificate is an important carrier for public key. With the development of self-organized networks and distributed networks, such as Ad Hoe Networks, a secure self-organized certificate management scheme is required urgently. In this paper, a new one-way hash chain based self-organized certificate management scheme is proposed. In this scheme, nodes themselves can create, disseminate, renew, certify and revoke the certificate without the supports by third trusted party online. As its security relies on the security of private key and the one-way hash chain, this scheme is more secure than previous ones.
