具有空间、时间双重分布性的随机会话密钥分发系统

A Distributed Random Key Distribution System with Distributed Characteristics of Space and Time

本文首先提出了分布式密码协议的空间分布性和时间分布性的观点 ,并从双重分布性的角度研究分布式密码协议 .作为一个例子 ,在V Daza的密钥分发系统中一个只具有空间分布性的分布式密钥分发系统的基础上 ,引入了前置安全 (proactivesecurity)体制 ,得到了一个具有空间和时间双重分布性 ,可以抵抗动态攻击者的分布式密钥分发协议 .拓展了分布式密码协议的研究空间 .同时 ,文中在建立概率空间的基础上 ,证明了分布式密钥分发系统的安全性 .

This paper first gives the notion about distributed cryptographic protocol with distributed characteristics of space and time.Then research distributed cryptographic protocol based on the notion.For an instance,we use proactive security in an distributed key distribution system only with distributed characteristic of space and give a distributed protocol against mobile adversary.This paper enlarges research field of distributed cryptographic protocol.At last,this paper proves the security of distributed random key distribution protocol based on the probability space.
