Abstract In recent years, chaotic systems are widely used in the secured transmission of images due to the inherent properties relevant to cryptography. In this article, a novel encryption algorithm based on hyperchaotic system is proposed. The algorithm employs a five dimensional (5D) hyperchaotic system with quadratic nonlinearity. The cryptographic operations such as confusion and diffusion are performed in an innovative way. Hybrid random matrix transform (HRMT) is proposed to perform confusion operation which is controlled by 5D hyperchaotic system. The algorithm is validated by presenting extensive simulation results and comparisons. The results show that the algorithm is capable of resisting various kinds of attacks. Ausführliche Beschreibung
