一种基于IDEA和ECC算法的数字化防伪认证新方案的研究与实现

商品防伪是一项系统工程，现有防伪措施在有效性和易操作性之间不能达到很好的统一，本文在研究商品防伪机制的基础上提出了一种有效解决上述问题的新方案．该方案通过IDEA比特流重组的加密算法对商品信息进行加密，以主密钥机制采用椭圆曲线密码算法ECC实现对IDEA密钥的自动化安全管理，而客户可依据加密产生的防伪码通过电话或网站快速准确认证其对应商品的真伪．理论分析和系统的实际运行表明该方案是一种有效、安全的新型实用方案．

Research on A Novel and Secure Authentication Scheme Based on IDEA and ECC Cryptography Algorithms

To solve the problem of low efficiency and weak security of traditional methods for protecting merchandise from being counterfeited, a novel and secure authentication scheme based on cryptography algorithms is proposed in this paper, where the symmetric cryptography algorithm IDEA is used to encrypt the merchandise data to mask code, while the public key cryptography algorithm ECC is to manage the IDEA key automatically. Thus customers can verify the validation of the merchandise quickly and correctly via telephone or Web site. Analysis manifests the scheme is efficient, secure, and practical.
