In this paper, a novel quantum encryption algorithm for color image is proposed based on multiple discrete chaotic systems. The proposed quantum image encryption algorithm utilize the quantum controlled-NOT image generated by chaotic logistic map, asymmetric tent map and logistic Chebyshev map to control the XOR operation in the encryption process. Experiment results and analysis show that the proposed...
For the rapid response and security requirements of network communication, this paper develops a new implement method of encryption and authentication scheme SM4-GCM on FPGA with low resource occupancy and fast processing speed. This method adopts the SM4 algorithm with independent intellectual property rights. Two SM4 modules are used during encryption to improve the data processing speed by Ping-Pong...
Recently, a number of chaos-based image encryption algorithms have been proposed. However, the initial parameters used in masking operation are usually fixed in the whole encryption process. In this paper, we introduce an efficient image encryption scheme of pixel bit based on combination of chaotic systems with variable initial parameters. The algorithm takes advantage of the best features of chaotic...
