The encryption algorithm for data encryption is proposed,which is based on chaotic map system.In the encryption process,we take the sine chaotic map and Chebyshev-map together that the structure is relative simple and generate a relatively complex sequence.Sensitivity and random testing of two chaotic mapping,two chaotic maps obtained with better cryptographic properties,and verify obtained the encryption system has better encrypted performance.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 processes of commodity circulation have a stronger function of anti-counterfeiting.
