随着无线自组织网络各种应用的提出，安全性已成为重大研究挑战之一，并受到越来越多的关注。在本文中，我们提出了一个分布式的密钥管理和认证方法，部署最近发展起来的概念，基于身份的密码和阈值秘密共享。该网络不需要假设节点之间存在任何预先确定的信任关系，以自组织的方式提供密钥生成和密钥管理服务，有效地解决了传统公钥基础设施（PKI）支持的系统中存在的单点失效问题。基于身份的加密机制不仅可以提供端到端的真实性和机密性，而且可以节省网络带宽和无线节点的计算能力。
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 and authentication approach by deploying the recently developed concepts of identity-based cryptography and threshold secret sharing. 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 service, which effectively solves the problem of single point of failure in the traditional public key infrastructure (PKI)-supported system. The identity-based cryptography mechanism is applied here not only to provide end-to-end authenticity and confidentiality, but also to save network bandwidth and computational power of wireless nodes.
