This paper introduces a new lattice system TMDPCML, which enhances the correlation dynamics of spatiotemporal behavior and improves the efficiency of energy diffusion between lattices based on performance test results. It has a larger parameter space, better chaos, and outstanding cryptographic characteristics. The application of TMDPCML system in private image encryption further verifies its good chaotic behavior and cryptographic requirements compliance.
This paper proposes a new tent-multi dynamic piecewise coupled mapping lattice (TMDPCML). Through the comprehensive analysis of the performance test results, TMDPCML system increases the correlation dynamics of spatiotemporal behavior and improves the efficiency of energy diffusion between lattices. Moreover, TMDPCML system has larger parameter space, better chaos and outstanding cryptographic characteristics. Therefore, this paper proposes a privacy image encryption algorithm combined with TMDPCML system. The application of TMDPCML system in private images encryption further proves that TMDPCML system has good chaotic behavior and meets the requirements of cryptography. (c) 2021 Elsevier Inc.
