| 摘 要： | 提出一种逻辑签署技术，以防范对打印信息的伪造、篡改及非法使用。将该技术应用于打印信息的防伪认证系统，设计并实现了该认证系统，使得打印信息的检验过程快速、便利、精准和实用。基于本技术设计的应用系统不依赖于网络和数据库，而且是一个开放体系。系统的核心思想是通过完整的逻辑体系保证其密码学意义上的安全性，具有密码学意义上的高安全性，突破了现有打印信息防伪认证技术的模式。

| Abstract: | A logic signing technique was developed to protect printed information from being forged,tampered with or possessed illegally.The technique was applied to anti-counterfeit authentication system of printed information to make it verified feasibly,quickly,conveniently and precisely.Its prototype was designed and implemented.The authentication system was totally independent of database and network.What's more,it is open and secure cryptographically due to the fact that the synthetic information on a printed certificate is associated logically with encrypted verification information,which essentially changes the mode of the existing anti-counterfeit techniques for printed information. |
