Mimicry decision parameter message synchronization device and mimicry decision parameter message synchronization method

Abstract

The invention provides a mimicry decision parameter message synchronization device and method. The mimicry decision parameter message synchronization device comprises an input agent, a redundant controller, at least two heterogeneous function equivalents and an output agent, the input agent is used for sending an external service request to the selected one or more heterogeneous function equivalents according to an agent strategy of the redundant controller after receiving the external service request; the redundant controller is used for reordering, shaping and comparing the judgment parameters of the heterogeneous function equivalents and informing the output agent of a judgment result; the heterogeneous function equivalence body is used for generating judgment parameters and sending thejudgment parameters to the redundant controller; the output agent is used for sending the output of the corresponding equivalent body as an external service response according to the judgment resultof the redundant controller. According to the scheme of timing batch synchronization, parameter shaping and the like of the mimicry judgment parameters, the judgment error probability caused by message disorder, packet loss and the like is effectively reduced, and the reliability of a mimicry safety system is improved.

Description

technical field [0001] The present invention relates to the technical field of cyberspace security protection, and in particular to a device and method for synchronizing messages of mimic ruling parameters. Background technique [0002] While cyberspace is developing vigorously, it is facing a severe security situation. There are a large number of malicious attacks against cyberspace. In addition, the network system is complex and inevitably has loopholes. Therefore, cyberspace has both external threats and internal security threats. Vulnerability issues are intertwined, and security risks are severe and complex. In the new cyberspace security situation, traditional defense methods based on prior knowledge are difficult to deal with various attacks. It is necessary to change defense thinking, define new defense boundaries, consolidate the depth of defense, and move from passive to active defense with endogenous security.

Problems solved by technology

[0003] Chinese patent CN201610853938.7 "A Device, Method, and Equipment for Encapsulating Heterogeneous Functional Equivalents" proposes a mimic security defense technology, which can obtain a favorable endogenous defense situation from initiative, variability, and randomness. The environment changes dynamically, which is difficult for attackers to observe and predict, thus greatly increasing the difficulty and cost of attacks including unknown exploitable vulnerabilities and backdoors

When the redundant controller receives the judgment parameters, since the same batch of judgment parameters is not generated by the same external service request, it cannot compare and select the normal heterogeneous functional equivalent, resulting in a judgment error
