随着无线自组织网络的各种应用被提出，安全性已成为研究的重大挑战之一，受到越来越多的关注。在本文中，我们利用最近发展的无证书公钥加密和阈值秘密共享方案的概念，提出了一种分布式密钥管理方法。该网络在不假设节点间预先存在信任关系的情况下，采用阈值秘密共享方案，以自组织的方式提供密钥生成和密钥管理服务，有效地解决了单点故障问题。这里应用无证书公钥加密不仅是为了消除对证书的需求，而且还保留了基于身份的密钥管理方法的理想属性，而没有固有的密钥托管问题。
As various applications of wireless ad hoc network have been proposed, security has become one of the big research challenges and is receiving increasing attention. In this paper, we propose a distributed key management approach by using the recently developed concepts of certificateless public key cryptography and threshold secret sharing schemes. Without any assumption of prefixed trust relationship between nodes, the ad hoc network works in a self-organizing way to provide the key generation and key management services using threshold secret sharing schemes, which effectively solves the problem of single point of failure. Certificateless public key cryptography is applied here not only to eliminate the need for certificates, but also to retain the desirable properties of identity-based key management approaches without the inherent key escrow problem.
