Inter-core communication method and device in multi-core microprocessor

Abstract

The invention relates to an inter-core communication method and device in a multi-core microprocessor, and the method comprises the steps: obtaining to-be-sent information which comes from a first core and is used for being sent to a second core; generating a target communication key according to a to-be-sent protocol header; encrypting the to-be-encrypted data through the target communication key to obtain encrypted data; transmitting the encrypted data and the protocol header to be sent to a second core; under the condition that the target information is determined to be information to be sent according to the target protocol header in the target information acquired by the second core, generating a target communication key according to the target protocol header, and sending the target communication key to the second core, so that the second core decrypts data to be decrypted in the target information through the target communication key to obtain decrypted data. According to the application, the purpose of encrypting the communication information between the dual cores can be achieved, and the problem that the confidential information of a user is leaked due to the fact that a hacker obtains the communication content between the cores through monitoring is prevented.

Description

technical field [0001] The present application relates to the technical field of microprocessors, in particular to a method and device for inter-core communication in a multi-core microprocessor. Background technique [0002] With the widespread use of IoT devices, the risks brought by them are becoming more and more obvious. For example, hackers can easily obtain the confidential information in the device, resulting in the leakage of user data, and modifying or replacing the program firmware inside will cause a major threat to the entire IoT network. [0003] In addition, as IoT applications become more and more complex, single-core microprocessors are no longer capable of complex tasks, and multi-core microprocessors have appeared on the market. [0004] During the process of realizing the present invention, the inventors found that the communication security among the cores in the multi-core microprocessor has become an important subject. [0005] Aiming at the technical...
