Problems solved by technology

However, when data is transmitted through the DCS controller, it is usually transmitted in the form of plain text, so that the DCS controller cannot verify the authenticity of the data. Transfer to DCS, attack or tamper with the final firmware program of DCS, resulting in internal changes of the firmware program
When the tampered firmware program is started, illegal users control various system functions of the DCS through the tampered firmware program, which reduces the security of the DCS

Abstract

The invention relates to the technical field of information security, in particular to a secure starting method and device of a firmware program, and the method comprises the steps: starting a presettrusted program, and transmitting the firmware program in a DCS to a preset security chip through the trusted program; starting the security chip to check whether the firmware program is a legal program or not; when the firmware program is a legal program, starting the firmware program; and when the firmware program is not the legal program, forbidding to start the firmware program. By applying the method, the legality of the firmware program in the DCS can be checked through the security chip so as to ensure that the firmware program is started when the firmware program is a legal program, and the security of the DCS is improved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a method and device for securely starting a firmware program. Background technique [0002] In the distributed control system DCS, each data transmission process of the DCS is realized by the DCS controller. However, when data is transmitted through the DCS controller, it is usually transmitted in the form of plain text, so that the DCS controller cannot verify the authenticity of the data. It is transmitted to the DCS, and the final firmware program of the DCS is attacked or tampered with, resulting in internal changes of the firmware program. When the tampered firmware program starts, illegal users control various system functions of the DCS through the tampered firmware program, which reduces the security of the DCS. Contents of the invention [0003] In view of this, the present invention provides a method for securely starting a firmware program. By ...
