摘　　要：针对彩色二维码在数据传输过程中存在的安全隐患,提出了一种彩色二维码混合加密编解码方案。先将发送方信息数据用DES算法密钥加密,再用接收方提供的RSA公钥对DES密钥进行加密,密文数据通过彩色二维码存储和传输;接收方接收密文数据后,先对彩色二维码进行解码,获得密文信息,再通过RSA私钥获得DES密钥信息,最后用DES密钥解密发送方的原始数据信息。该方案具有无密钥传输、双密钥解密、混合密文无法被单一攻击算法破解等优点,从而保护了彩色二维码的编码信息。不同加密算法下彩色二维码信息的加解密效率测试结果表明,在相同密钥长度和高安全性要求下,该混合算法对数据的加解密效率最高,且在脱离网络连接的情况下,彩色二维码系统也可进行正常的加解密操作,提高了安全性和信息数据传输效率。In order to solve the hidden danger in the process of data transmission by color QR codes,a color QR code mixed encryption encoding and decoding scheme is proposed in this paper.In this scheme,the sender information data is encrypted with the DES algorithm key,and then the DES key is encrypted through the RSA public key provided by the receiver,and the cipher text information data is stored and transmitted through the color QR code.After receiving,the receiver first decodes the color QR code to obtain cipher text information,then obtains DES key information through RSA private key,and finally decrypts the original data information of the sender with DES key.The scheme has the advantages of no key transmission,double key decryption and mixed ciphertext can not be cracked by a single attack algorithm,so as to protect the coded information of color QR codes.The encryption and decryption efficiency of color QR code information under different encryption algorithms is compared through experimental tests.The test results show that the hybrid algorithm has the highest efficiency in encrypting and decrypting data under the condition of the same length and high security requirements.And in the case of out of the network connection,the color QR code system can also be normal encryption and decryption operation,not only improve the security,but also improve the efficiency of information data transmission.
