Abstract


Traditional software encryption technology is getting more and more can't meet the demand for speed in the information security and system security. Involved in a lot of information security system, people often use cryptographic algorithms to improve public key cryptography coprocessor operation speed and the safety of the system. Combined with the characteristics of the hardware encryption and software encryption, this article designed a power based on the mould take a coprocessor, hardware and software combination of RSA encryption system, and on MPC8347 hardware platform. The encryption system's main function is to realize the data signature/authentication and encryption/decryption, key generation and distribution, certificate of analysis/generation. The encryption system design including module, the RSA certificate module, key management module and coprocessor underlying the design of the control program. In order to improve the encryption strength of the encryption system, this paper also presents a 2048 bits RSA algorithm based on 1024 bits coprocessor implementation method. For RSA encryption system, this paper builds a performance test platform, in the process of performance testing, in order to improve the efficiency of the communication between the client and encryption system, a MAC package for communication between two communication parties. Performance test results show that the encryption system on network packet encryption processing performance has reached the expected goal.
