Method and device for data encryption and decryption

摘要

Various embodiments are described herein for a device and associated method for performing lightweight public key encryption and optionally corresponding decryption. In at least some embodiments, the lightweight public key encryption uses a CRT randomized-square operation 5 rather than expensive big integer arithmetic. Furthermore, in at least some embodiments the payload data is included in the random masking variable r thereby allowing more data to be encrypted in less time. 110- -112 PORT MODULE 1 102 . /*106 NETWORK + PROCESSOR COMMUNICATIONS INTERFACE MODULE DATA MEMORY OPERATING 114 STORE MODULE SYSTEM PROGRAMS ~116
