摘要
为了防范对打印信息的伪造、篡改及非法使用,提出了一种逻辑签署技术,设计并实现了基于该技术的防伪认证系统,通过完整的逻辑体系保证其密码学意义上的高安全性,使得打印信息的检验过程快速、便利、精准和实用。该系统是一个开放的不受具体物理设备限制的体系,突破了现有打印信息防伪认证技术的模式。
To protect printed information from being forged, tampered with or misappropriated, a logic signing technique is developed, which is applied to anti-counterfeit authentication system so as to make printed information verify quickly, conveniently, precisely and feasibly. The technique is independent of what physical equipment used, the system based on the technique is characteristically open and secure cryptograpbically due to the logical association between synthetic information and encrypted verification information, which essentially changes the mode of the existing anti-counterfeit techniques for printed information.
