Abstract: The encryption 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.
