Design of a new kind of encryption kernel based on RSA algorithm Shi Xiang-dong， Dong Ping (Information Engineering School，University of Science and Technology Beijing，
Beijing 100083，China) Abstract：This paper mainly analyzes the core operation of RSA algorithm－modular power operation, proposes an ameliorative algorithm which makes for hardware realization, and improves the operation speed of RSA decryption and Digital Signature with the Chinese remainder theorem. Based on these, a new kind of encryption kernel has been proposed and designed with relative simple structure and fast operation speed. Furthermore, simulation with Verilog HDL model validates the feasibility of the new encryption kernel.
