大规模延迟容忍网络中基于分级身份的认证密钥协商协议
Hierarchical identity based authentication key agreement in large-scale delay tolerant networks
摘要
Abstract
Large-scale delay tolerant network has the character of large scale deployment,long intermittent connection and communication delays.The traditional authentication key agreement schemes have the problem of management bottleneck and long communication delay.This paper proposed an authentication key agreement protocol for large-scale delay tolerant networks using hierarchical identity based cryptography.The protocol avoided management bottleneck by key delegating generation,and reduced communication delay by removing certification.Compared with other similar protocols,the communication and bilinear pairing computations overhead of the proposed protocol are small and constant.It is attractive in the environment of large delay tolerant network.It proved the security of the protocol in the standard model.关键词
