烟草企业成品卷烟防伪加密系统总体设计

System Design of Finished Cigarette Security Encrypted System in Tabacoo Companies

烟草企业致力于设计出一套安全、高效的卷烟防伪码实现方案,给企业生产的每一包成品香烟分配一个唯一代码,实现卷烟的防伪和促销。设计一种基于RC-5的改进算法并将其应用于集团企业成品卷烟的防伪认证及积分促销活动,通过基于RC-5的改进算法在卷烟防伪码上的应用充分认证此算法的高效性和安全性。

The tobacco companies are committed to design a safe,efficient implementation of cigarette security code,and each packet of Ready-made cigarettes is assigned a unique code to achieve anti-counterfeiting and promotion of cigarettes.This thesis aims to design a modified algorithm which based on the RC-5 and could apply it to Security certification and promotion of cigarettes in conglomerate,and could fully certificate the algorithm＇s security and high efficiency by the application in Cigarette Security Code which based on the modified algorithm.
