A Homomorphic Encryption Algorithm for Chaotic Image Coding Data in Cloud Computing

The traditional image data encryption methods tend to ignore the classification of encryption attack types, resulting in poor security and accuracy of encryption results. In order to better guarantee the performance of chaotic image coding, a homomorphic encryption algorithm for chaotic image coding data in cloud computing environment is proposed. First, the homomorphic encryption matrix of coded data is normalized, and the homomorphic encryption parameters are calculated according to the results of the specification. According to the encryption parameters, the image encoding instructions are set, the common encryption attack types are divided, the encryption instructions are selected according to the partition results, and the accurate encryption of chaotic image coding data is finally realized. Finally, the experimental results show that the homomorphic encryption algorithm of chaotic image coding data in cloud computing environment has higher security and accuracy than the traditional encryption algorithm. It is indicated that the proposed encryption algorithm has a certain feasibility.
