Mimicry network topology transformation method

Abstract

The invention discloses a mimicry network topology transformation method, which is used for overcoming problems to be solved in dynamical change of a network structure in the prior art. The mimicry network topology transformation method disclosed by the invention comprises the following steps: once equivalent transformation step of a local subnet comprises: A1, determining the local subnet to be performed with topological equivalent transformation; A2, using a network description method to carry out abstract description on the local subnet determined in A1; A3, establishing an equivalent subnet of the local subnet described in A2 based on a constraint condition; and A4, using the established subnet to replace the original subnet. Compared with the prior art, the mimicry network topology transformation method disclosed by the invention has the following advantages: 1. the method is used for achieving an overall network topology transformation effect by carrying out topological equivalent transformation on the local network subnet for multiple times, since the target of the topology transformation is the subnet in the network instead of the entire network, the network scale of the topology transformation is greatly reduced, and the difficulty of the topology transformation is reduced.

Description

technical field [0001] The invention relates to a transformation method in the technical field of computer communication, in particular to a method for topology transformation of a mimic network. Background technique [0002] The basic idea of ​​mimic security defense is to dynamically construct diverse mimic environments such as networks for the purpose of providing dynamic, non-deterministic, heterogeneous, and non-sustainable target environments under the condition of functional equivalence. A controllable way to implement active jumps or rapid migrations between diverse environments, which is difficult for attackers to observe and predict changes in the target environment, thus increasing the difficulty and cost of attacks including unknown exploitable vulnerabilities and backdoors . That is, to fight unknown threats with uncertainty. [0003] The security of the mimic network is reflected by the uncertainty of the network, and the uncertainty of the structure is its i...
