A modified serpent based algorithm for image encryption

According to the fast progression of digital communication systems, information security becomes indispensable in data exchange and storage. There are wide uses of images in medical and industrial processes, so it is necessary to sustain the confidential image's data from unauthorized access and disclosures. This paper proposes a new modification on the Serpent algorithm for image's encryption which based on chaotic mapping and cyclic group substitution instead of byte substitution transformation (DES S-Box) which will decrease the number of rounds and the time usage. A comparison with the classical AES will be declared. The empirical results approved that the modified encryption algorithm provides comparable security and higher performance than the classical Serpent. Elaborated results in terms of implementation, security analysis and statistical tests are declared. Comparative study with classical Serpent encryption algorithms is shown the notability of our modification.
