摘要： 该文在研究商品防伪的基础上提出了一种面向认证的传统商品数字化新型防伪方案，其思想是基于数据加密算法IDEA对商品信息进行加密生成防伪码，并采用椭圆曲线密码算法ECC对IDEA密钥实行自动化安全管理, 客户依据防伪码通过电话或网站快速准确认证对应商品的真伪,而认证中心可通过对认证日志的分析为追踪打假提供决策支持，从而达到综合防伪的目的,分析表明该方案是一种有效、安全的新型实用方案，最后基于该机理给出了方案的实现。

Abstract: On the study of merchandise countfeit, a new authentication-oriented solution bases on the IDEA and ECC algorithms for traditional merchandise is proposed in this paper, where IDEA is used to encrypt the merchandise data to Mask Code, while ECC algorithm for the management of the IDEA key automatically, and then customers can verify the validation of the merchandise quickly and correctly via telephone or Web site, thus CA can provide decision support for countfeit by authentication log ,and analysis manifests the solution is valid, safe and useful.
