Abstract

The invention discloses a processor. The processor comprises a configuration information storage region and a recombination control unit; the configuration information storage region is used for storing configuration information, and the configuration information comprises a recombination rule; the recombination control unit is used for controlling a connection relationship among logic devices inthe processor; and the recombination control unit is used for receiving a control instruction obtained by an application which is running in the processor through decoding, selecting the correspondinglogic devices to form a recombination circuit for executing the control instruction according to the recombination rule in the configuration information storage region, thereby realizing execution ofthe control instruction. The processor can control the logic devices forming the recombination circuit; and when one control instruction is realized, the processor can select the logic devices to beconnected to form different recombination circuits according to the recombination rule as needed, so that the cracking cost of the control instruction execution process is effectively reduced, the execution security of the control instruction corresponding to the application, in the processor, in the running process is improved, and the processor is securer and more stable.

Description

technical field [0001] The invention relates to the technical field of processors, in particular to a processor with a high security level. Background technique [0002] Due to the rapid development of information technology, the importance of information security is increasing day by day. To keep information safe, processor security must be ensured. Security processor is a key technology in the field of information security. [0003] The current "secure processor" mainly realizes the security processing of the processor by running encryption algorithm software. However, this kind of encryption algorithm has a high probability of being cracked, and the implementation of the encryption algorithm greatly reduces the overall performance of the processor. security is no longer applicable. Contents of the invention [0004] In view of this, the present invention provides a processor to at least partly solve the above problems. [0005] The invention provides a processor, i...
