Embodiment Construction

[0059] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the present invention Examples, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0060] Under the DHR architecture, the existing voting method generally adopts the k / n voting method, that is, among n executive bodies, at least k executive bodies have the same operation results, and the operation results are taken as the output results of the system. In practice, due to the complexity of network space, the diversity of network attacks, and the influence of fac...

Abstract

The invention provides a trust-based mimic defense voting mechanism and system. The mechanism includes: Step 1: Count each executive body according to the calculation results of each executive body in the mimic defense system; Step 2: According to the counting result, estimate the statistical trust degree of each executive body at the current moment based on the Bayesian estimation theory; Step 3: Select the calculation result of the executive body with the highest statistical trust at the current moment as the output of the mimic defense system in the case of unable to vote. According to the historical performance records of each executive, the present invention constructs a trust measure for each executive. When encountering the above-mentioned failure to vote, the calculation result of the executive with the largest statistical trust degree is selected as the output result of the system, which can maximize to avoid the attack escape problem.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a trust-based mimic defense voting mechanism and system. Background technique [0002] With the rapid development of information and network technology, people's daily work and life are increasingly dependent on the network, making cyberspace an important support for today's social functions and social activities. One of the root causes of serious threats to cyberspace security lies in the long-term existence of software and hardware vulnerabilities and backdoors. The security loopholes in the software and hardware of the information system have become the decisive factors that directly affect the security. Practice has proved that the vast majority of information security incidents are initiated by attackers with the help of software and hardware vulnerabilities. At present, there is no effective theoretical and technical solution to the problem of loopholes caused by...
