Problems solved by technology

[0004] Due to external attacks or internal errors, the heterogeneous executive body may be abnormal. Although the abnormality may not affect the judgment output data, the security of the system will be significantly reduced if the heterogeneous executive body is not cleaned and restored in time.

Embodiment 1

[0025] This embodiment describes a method for cleaning and restoring heterogeneous executives, which is applied to an analog switch with a heterogeneous multi-mode architecture. The switch includes a switching chip, an analog scheduler, and multiple heterogeneous executives. The scheduler is based on the analog judgment result and The imitation decision strategy determines whether the heterogeneous executive needs to be cleaned and restored, and informs the designated heterogeneous executive to clean and assist it to complete the state recovery. Specific related modules such as figure 1 shown, where

[0026] The heterogeneous executive module includes multiple processors with different architectures (such as X86, ARM, RISC-V, MIPS, etc.), and the control plane software of the corresponding protocol runs on the heterogeneous executive;

[0027] The mimic scheduler includes a mimic judgment module, a recovery agent module, and multiple data communication interfaces to communica...

Embodiment 2

[0043] This embodiment describes a cleaning and recovery device for a heterogeneous executive body of a mimic switch, which is used in a mimic switch. In the scheduler, it includes a mimic judgment module and a mimic recovery module, where

[0044] The mimic judgment module connects multiple heterogeneous executives through the data communication interface, and is used to judge the downlink data from the heterogeneous executives. For any heterogeneous executive with normal output, it sends the correct data to the exchange Chip; for heterogeneous executives with abnormal output, decide whether to clean them according to their current status and historical judgment data;

[0045] The mimic recovery module is connected to the switch chip through the data communication interface, and is used to receive the uplink data and the judged downlink data from the switch chip, maintain and update the data backup of the current running status of each heterogeneous executive body, and clean ...

Abstract

The invention discloses a heterogeneous executor cleaning recovery method and device in a mimicry switch. The method comprises the steps that a mimicry scheduler judges downlink data from a pluralityof heterogeneous executors, and marks a to-be-cleaned specified heterogeneous executor; specifying a heterogeneous execution body to restart, and then specifying the heterogeneous execution body to send a normal protocol negotiation message to try to interact with the mimicry scheduler; the mimicry scheduler detects whether the specified heterogeneous executor is in a cleaning state or not according to the protocol negotiation message, the message sending process is repeated until the state of the specified heterogeneous executor is recovered, and the mimicry scheduler is notified; and the mimicry scheduler marks that the state of the specified heterogeneous executor is normal. According to the method, under the condition that protocol stacks on the heterogeneous executors do not need to be modified, the normal working state can be quickly restored when one or more heterogeneous executors are attacked by the outside or the inside of the heterogeneous executors is abnormal, and the method has important guiding significance for the cleaning and restoring technology of the multimode heterogeneous executor architecture system.

Description

technical field [0001] The invention belongs to the technical field of network security protection, and in particular relates to a method and device for cleaning and restoring a heterogeneous executive body of an imitation switch. Background technique [0002] At present, the security problem of cyberspace has increasingly become one of the most serious challenges in the information age, and the theory of mimic defense provides a good guide for solving the security problem of cyberspace. Mimic defense technology achieves effective response to unknown threats by creating an architecture centered on dynamic heterogeneous redundancy. [0003] Mimic switch is a typical application of mimic defense technology. Usually, multiple heterogeneous processors are used as heterogeneous executives, and the system includes a hardware-implemented mimic scheduler to implement decision screening of downlink data of heterogeneous executives and distribution of uplink data. [0004] Due to ex...
