摘　　要：提出了一种基于双重混沌映射系统对商品的生产号进行数字加密的加密算法.在加密的过程中用二维lo-gistic映射和Henon映射联合对商品的生产号进行加密,得到商品的防伪码,并对双重混沌映射的性能进行了分析,利用双重混沌系统的伪随机性、初值敏感性、遍历性等所特有的性质,得出双重混沌映射具有良好的密码学特性,提高了算法的复杂度,增大了算法的密钥空间,增加了破译的难度,使商品在流通的过程中具有更强的防伪性能.The eneryption algorithm of commodity production number for data encryption is proposed, which is based on double chaotic map system.. In the encryption process, After we take the two-dimensional logistic map and Henon map together for the number of commodity production of scrambling encryption, we obtained the anti- counterfeit of commodity. Meanwhile, the performances under the double chaotic map are analyzed. Utilize the pseudo-randomness and initial value sensitivity and ergodicity characteristic of the double chaos map, The results show that double chaotic map have the good properties of cryptographic, which makes constructing algorithm more complex, key space of algorithm will be bigger and it＇s harder to break into this cryptosystem, As a result, the goods process of commodity circulation have a stronger function of anti-counterfeiting.
