DEVICE FOR SIMULTANEOUSLY ACHIEVING RSA/ECC ENCRYPTION AND DECRYPTION ALGORITHMS

摘要

Embodiments of the present invention provide a device for simultaneously achieving RSA/ECC encryption and decryption algorithms, comprising: a CPU interface module configured to receive a configuration parameter and send the configuration parameter to a main control module, and to return a state parameter; the main control module configured to receive and store the configuration parameter, to send, according to the configuration parameter, a computation command to a complex computation control module, to send the state parameter to the CPU interface module, and to receive a read command and send a computation parameter to a basic computation module; the complex computation control module configured to receive the computation command, to generate an operation command according to the computation command and send the operation command to the basic computation module, and to receive a completion signal of the basic computation module; the basic computation module configured to receive the operation command, to send the read command to the main control module to obtain the computation parameter, to complete computation according to the operation command and the computation parameter, to send the completion signal to the complex computation control module, and to send the computation result to the main control module.
