Computer architecture and access control method, data interaction method and secure startup method in computer architecture

Abstract

The embodiment of the invention provides a computer architecture and an access control method, a data interaction method and a safe starting method in the computer architecture. The computer architecture comprises a plurality of processor cores, a bus connected with the processor cores, a main bridge connected with the bus and a memory connected with the main bridge. At least one processor core in the plurality of processor cores is a secure processor core, and an access address generated by the secure processor core is a secure access address; at least one processor core in the plurality of processor cores is a common processor core, an access address generated by the common processor core is a common access address, and the security access address is different from the common access address; the security processor core and the common processor core perform data interaction with the main bridge through the bus; and the main bridge executes data access to the memory based on the safe access address and the common access address transmitted by the bus, and the computer architecture improves the performance of the system.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of software security, and in particular to a computer architecture and its internal access control, data interaction and security startup methods. Background technique [0002] With the development of information technology, especially the development and popularization of cloud computing technology, more and more customers deploy their business systems on the cloud, thus making services related to cloud information security such as electronic signatures, electronic contracts, online payments and The importance of digital certification, etc. is becoming more and more prominent. How to build a credible digital security platform has become the technical focus of people's attention. [0003] As a computer technology applied to the cloud, virtualization technology can virtualize multiple virtual machines (Virtual Machine, VM) through the host to realize efficient utilization of the har...
