A CA is suitable for hardware implementation. We demonstrate that the CA-based stream cipher, which is implemented in the field-programmable gate arrays (FPGA), has a high encryption speed in a real-time video encryption and decryption system.to be published in Journal of Signal ProcessingChaotic DynamicsCellular Automata and Lattice Gasestext
