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...

The invention provides a multi-queue random parameter normalization device suitable for a mimicry defense system. The device is used for normalizing and representing random parameter requests of different applications by calculating hash values of the random parameter requests, representing application conditions of queue storage random parameters in different execution by utilizing random parameter effective tags, and providing unified random parameters for heterogeneous executors of the mimicry defense system based on a multi-queue parallel comparison mode. According to the multi-queue random parameter normalization device, the synchronization problem of out-of-order random parameter requests can be solved, and the random parameter synchronization matching efficiency is improved. According to the invention, random parameter application requirements of random numbers and timestamps are normalized into a unified hardware device, and an integrated solution can be provided for random parameter normalization of the mimicry 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...
