基于不经意传输的拓扑隐藏广播协议设计
Design of a Topology-hiding Broadcast Protocol Based on Oblivious Transfer
摘要
Abstract
In order to protect sensitive information such as node relationship and geographical position,an efficient public key cryptosystem named NTRU( Number Theory Research Unit) is introduced into oblivious transfer protocol and an untrusted third party is used to hide the intermediate process of broadcasting for the sake of topological privacy. The protocol can be considered as the implementation of topology hiding broad―cast,and it addresses some uncovered problems of its previous conceptual schemes such as key reconstruc―tion,confidentiality of IDs within neighboring nodes as well as nodes network dynamicity. Security and per―formance analysis indicates that the proposed protocol endures topology concealment as long as any part of the network is corrupted,and manifests its merits of low computation and communication overheads as well as the advantage of independence on node degree.关键词
