Computer security starting method based on heterogeneous multi-core chip

Abstract

The invention discloses a computer security starting method based on a heterogeneous multi-core chip. The method includes: using at least one trusted core on the basis of a heterogeneous multi-core platform to ensure security of an untrusted core. The trusted core is used as a monitoring core, and the untrusted core is used as a computing core; the trusted core and the untrusted core are heterogeneous, and a CPU core with independent intellectual property is a first choice of the trusted core. The trusted core and the untrusted core are isolated by hardware, and sensitive hardware resources are collected to the trusted core. The trusted core is communicated with the untrusted core through cooperation of shared memory and inter-core interruption. The trusted core is guided by adopting a self-developed system, and provides security services outwards, and the untrusted core is guided by adopting a UEFI (Unified Extensible Firmware Interface) system. A core of the method is to ensure the security of the untrusted core on the basis of the heterogeneous multi-core platform through the trusted core. Realization of the method is not limited by specific platforms and starting manners, and the method can be applied simply with the need for satisfying basic requirements.

Description

technical field [0001] The invention relates to the technical field of modern computer safe booting, in particular to a computer safe booting method based on heterogeneous multi-core chips. Background technique [0002] With the development of information technology, computers have become an indispensable part of our daily life, but it brings information services to people and also brings threats to information security, especially in the defense industry, aerospace, etc. important areas, this is even more prominent. At present, various computer viruses emerge in an endless stream, and trusted computing has also become a research hotspot of computers. However, most of the current research on trusted computing focuses on the operating system level, that is, how to kill viruses and resist attacks after the computer starts the operating system. There is little research on the process, which leads to the lack of effective solutions for BIOS (Basic Input Output System) attacks. ...

AI Technical Summary

Problems solved by technology

Second, after the computer is powered on, the first part of the code executed as the trust root of the trust chain is unconditionally trusted, so if the trust root is attacked, the entire platform is still insecure

Third, the current most popular processors are basically x86 architecture, and its core technology is controlled by Intel Corporation. We cannot fully grasp the behavior of this processor, which is also a hidden danger to our sensitive information.
