摘    要:通过对各种数字签名算法与代理签名算法的比较,提出一种适用于无线通信系统的基于代签名的数字认证(数字签名)方案。把数字签名和信息加密过程逻辑地合并,极大降低计算复杂性。并把对无线通信网中多个接收方的签名加密的巨大计算量转移到授权代理,从而满足无线通信系统的实时性要求。还分析了该方案的安全性和有效性。指出该方案可用于现在应用广泛的在线交易系统和构筑网络安全服务协议。

关 键 词:计算机通信  网络安全  通信协议  签名加密  代理签名  数字认证  无线通信网

Abstract:This paper compares several kinds of digital signature methods with proxy signature arithmetic and proposes a new digital authentication scheme for broadcast communication system based on proxy signcryption .This scheme combines the two step process of digital signing into one logically, which lowers the computing complexity greatly. Another advantage of this scheme is to transfer heavy computional work to the authorization proxy, which has strong computation power and is able to deal with signcryption process for many receivers at the same time. In this way, all the receivers will be responded in a contented time. The paper also discuses the security and effectiveness of the scheme and points out that this scheme may be used in the on line business system widely and constructs network security protocal.
Keywords:computer communication  network security  communication protocol  signcrytion
