Abstract

The aim of this study is proposing a novel chaotic system in which the variables of the system are treated as encryption keys to achieve secure transmission of digital images. The proposed system has high sensitivity to the variation of its initial values and parameters producing unpredictable trajectories. The novel system successfully passes the 0-1 test and FIPS PUB 140-1 statistical tests that check the distribution of the distinguished elements by generated chaotic sequences. The results obtained proved the robustness of the image encryption/decryption system based on sequences generated from the proposed chaotic generator.
