基于多重水印的移动通信认证系统

分析基于数字签名认证系统的认证机制、基本结构及存在的安全缺陷，提出一个基于双钥密码体制和多重水印技术的移动通信认证系统。通过在系统中嵌入一个鲁棒水印和半脆弱水印，实现发信人身份认证和数据完整性认证的功能。可对修改、伪造传输信息等非法操作进行认证。分析表明，该系统具有结构简单、安全性强、可信度高、认证精度高等特点。

Mobile Communication Authentication System Based on Multiple Watermarks

This paper dicusses the issues of authentication mechanism and framework of the digital signature system. Based on the analysis of the security gap in the authentication mechanism using digital signature,a novel authentication system combining asymmetric key cryptography and multiple watermarks technique is proposed. A robust watermark and a semi-fragile watermark are embedded in the information to carry out the functions of ID authentication and data integrity authentication. Illegal access to system,editi...
