摘　　要：对于车载自组织网络密码学是其解决网络安全解决方案的基础,公钥技术中的基于身份认证技术在车载自组织网络中十分有效,这主要归功于它简单的密钥管理过程和降低了内存存储的开销。然而目前对基于身份认证的密钥管理方案的研究不完善。当前方案要么没有考虑到车载自组织网络的必要需求,如缺少管理中心;要么不能处理重要技术运作,如密钥的撤销和更新。因此,本文提出一种IBC(Identity-Based Cryptography)方案,该方案是一种基于车载无线网络的完全自组织身份认证密钥管理方案。IBC不依赖任何认证中心或则可信第三方,即使在网络进行组网过程中。另外,IBC能够提供一种机制去撤销恶意或则被盗用节点的私钥同时更新未被盗用节点的密钥。仿真显示IBC不会对网络造成过高通信开销的同时依然十分有效。Cryptography is the basis of security solutions for mobile ad hoc networks. Among public key techniques, the identity - based ones are very attractive for mobile environment, mainly due to their simple key management process and reduced memory storage cost. Current solutions either do not consider the main requisites of these networks, as the absence of central administration or self-organization or do not deal with important operations, such as key revocation or key update. Thus, this paper presents IBC（ Identity-Based Cryptography） , a complete and fully self-organized identity-based key management scheme for mobile ad hoc networks. IBC does not depend on any central authority or third trusted party, even during the network formation. Also, IBC provides mechanisms to revoke the private key of malicious or compromised nodes and ways to update the keys of non-compromised nodes. Simulation results show that IBC is effective while it does not impose a high communication overhead to the system.
