密钥管理是构建其他安全基元的基本加密基元。在adhoc网络中密钥管理问题的解决方案中，密钥预分配方案(KPS)似乎是一种实用的方案，可以容忍拓扑变化和链路中断。然而，依赖受信任的经销商，虽然只在初始化时需要，但使KPS在许多自组织网络场景中不适用，并导致单点漏洞。提出了分布式密钥预分配方案(DKPS)的协议，该方案不需要可信密钥分发者，实现了完全分布式、自组织的密钥预分配方案，不依赖于任何基础设施的支持。重点研究了DKPS的一个组成部分--安全共享密钥发现(SSD)，并给出了实现它的两种协议。
Key management is an essential cryptographic primitive upon which other security primitives are built. Among the solutions to the key management problem in ad hoc networks, key pre-distribution schemes (KPS) seem to be a practical option, tolerant to changing topology and broken links. However, relying on trusted dealers, although only needed in initialization, renders KPS inapplicable in many ad hoc network scenarios and lead to a single point of vulnerability. We present protocols for the distributed key pre-distribution scheme (DKPS) paradigm, which eliminates the need of a trusted dealer in KPS and realizes fully distributed and self-organized KPS without relying on any infrastructure support. We especially focus on the secure share d key discovery (SSD), a component of DKPS, and present two protocols to realize it.
