| Summary: | The chaos-based image encryption algorithm using parallel computing is described. To reduce the amount of encrypted data the wavelet-based compression is used. Some of the wavelet coefficients are encrypted with the use of confusion-diffusion scheme and the qualifying coefficients are encrypted by the algorithm based on reversible cellular automations. Resistance of this algorithm to statistical and differential cryptanalysis was evaluated. The SP 800-22 statistical tests were performed. These tests demonstrated that the binary sequence generated by the algorithm is close to the random one. The algorithm testing was performed. The algorithm productivity was estimated. The encryption rate for the test image in the case of lossless compression was 8 Mbit/s. |
