Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0038] The random parameter normalization device described in the present invention is connected with the heterogeneous executive body environment in the mimic defense system, and the specific position and function are as follows figure 1 shown. The device is responsible for receiving random parameter requests initiated by different executives, and feeding back random parameter results to corresponding executives according to actual conditions. It is guaranteed that random parameter requests initiated by sessions of the same function of different executives at different times can obtain the same normalized value.

[0039] The overall structure schematic diagram of the random parameter normalization device is as follows: figure 2 shown. Including random parameter service control interface, random parameter generator, hash function calculato...

Abstract

The invention provides a multi-queue random parameter normalization device suitable for a mimic defense system, which normalizes random parameter requests representing different applications by calculating hash values ​​of random parameter requests, and uses random parameter effective tags to represent queues and store random parameters. Based on the application of parameters in different executions, based on the method of parallel comparison of multiple queues, uniform random parameters are provided for the heterogeneous execution bodies of the mimic defense system. The proposed multi-queue random parameter normalization device can solve the synchronization problem of out-of-order random parameter requests and improve the efficiency of random parameter synchronization matching. The invention normalizes the random parameter application requirements of random numbers and time stamps into a unified hardware device, and can provide an integrated solution for the normalization of random parameters of the mimic defense system.

Description

technical field [0001] The invention relates to the technical field of mimic defense. In particular, it relates to a random parameter normalization method and device based on multiple queues. Background technique [0002] Limited by the level of technological development, people are currently unable to control the industrial chain of information system product production, nor can they make comprehensive and reliable detection of the vulnerability backdoors of information system products. The attack threat based on the backdoor of unknown vulnerabilities has become a world-class security defense problem, and the traditional security defense methods based on prior information can only have the effect of remedying the situation. In this context, Wu Jiangxing, academician of the Chinese Academy of Engineering, proposed the theory of mimic defense based on the consensus mechanism. Through the "dynamic-heterogeneous-redundant" system architecture, the uncertain disturbance proble...
