Embodiment Construction

[0060] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0061] like figure 1 As shown, an information security protection method for an embedded system of a power terminal, which actively performs information security protection through immune self-stabilization, immune monitoring, and immune defense methods based on the principle of artificial immunity, includes the following steps:

[0062] S1, establish an embedded system endogenous trusted operating environment for immune self-stabilization;

[0063] S2, loading an embedded system anomaly detection logic check program for immune monitoring;

[0064] S3, according to the result of the check in step S2, choose whether to load the fault emergency handling and event recording program for immune defe...

Abstract

The invention discloses a power terminal and an information safety protection method and system of an embedded system of the power terminal, information safety protection is actively carried out through immune self-stabilization, immune monitoring and immune defense modes according to an artificial immune principle, and the method comprises the following steps: S1, establishing an embedded systemendogenous credible operation environment for immune self-stabilization; S2, loading an embedded system abnormality detection logic inspection program for immunomonitoring; S3, selecting whether to load a fault emergency processing and event recording program for immune defense or not according to the result checked in the step S2: if the result checked in the step S2 is abnormal, loading the fault emergency processing and event recording program for immune defense; otherwise, not loading. According to the invention, three major functions of immune self-stabilization, immune monitoring and immune defense of human immunity are simulated, the power terminal is endowed with an anthropomorphic active immune safety protection capability, the information safety of the power industrial control terminal is maintained to a certain extent, and the safety risk of the power terminal is reduced.

Description

technical field [0001] The invention relates to the technical field of power system information security, in particular to an information security protection method and system for a power terminal and an embedded system thereof. Background technique [0002] Traditionally, the power system mainly relies on boundary isolation and dedicated system private protocols to ensure network security. Generally, power terminals are developed based on general-purpose software and hardware platforms. Except for user smart terminals that rely on the relatively simple SM1 national secret algorithm to ensure security, network security protection is rarely considered. . [0003] In recent years, advanced persistent threats (advanced persistent threat, APT) with malicious codes such as "Stuxnet", "Flame" and "Black Energy" as the main technical means have caused great harm to energy and other industrial control systems. The process is very hidden, and it can break through the existing securi...
