Abstract: According to the characteristics of Ad Hoc networks, such as mobility and self-organization, an identity-based key management scheme for Ad Hoc networks was proposed. In the paper, by the method of secure distributed key generation based on threshold cryptography, the interior members of Ad Hoc networks collaborated to conduct the system private key. Compared with the existent protocol, the proposed scheme, does not require the fixed structure of service nodes, and service nodes can dynamically join and leave network. At the same time, the system key is updatable among service nodes. The analytical results show the proposed scheme is flexible and secure, and it is suitable for Mobile Ad Hoc Network (MANET).

摘要: 鉴于Ad Hoc网络的可移动、自组织性等优点,提出了一种适用于Ad Hoc网络的基于身份的密钥管理方案,所提方案在门限密码学的基础上以完全分布化方式建立系统密钥。与已有的Ad Hoc网络密钥管理方案相比,它不需要固定的密钥服务节点组,密钥服务节点可以动态加入和撤离,而且系统密钥在密钥服务节点组内还可以动态更新。分析结果表明所提方案具有灵活、安全的特点,较好地适应了移动自组网(MANET)。
