Network dynamic defense method, device and system based on random multidimensional transformation

Abstract

The invention belongs to the technical field of network security, and particularly relates to a network dynamic defense method, device and system based on random multidimensional transformation, and the method comprises the steps: registering the identity of a legal user, and storing the attribute information of the user in a database; judging whether an end node user is a registered user or not through the access user attribute information; extracting a hopping address selection range and a hopping period by using a user private key, generating a hopping address, and verifying the validity ofthe hopping address according to a request message of accessing the network service by the user node; and sending the encrypted service resource list to the user node passing the verification, wherein the user node decrypts the encrypted service resource list by using the private key and then accesses the service resources of the corresponding security level. To solve the problems of easy collision, low distribution efficiency and the like of address conversion, a dynamic network view is constructed through continuous conversion of whole network end nodes, the uncertainty of a network structure and a target node is increased, and non-detection defense and effective management of whole network node conversion are realized.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a network dynamic defense method, device and system based on random multidimensional transformation. Background technique [0002] With the continuous development of network technology, the Internet has become an increasingly important strategic infrastructure; network applications are also constantly affecting people's way of life. In recent years, with the continuous exposure of major security incidents such as "Prism Gate", SWIFT banking system turmoil, and Dyn downtime, the issue of cyberspace security has become more prominent, and its importance is self-evident. The asymmetric security situation of "easy to attack but difficult to defend" in cyberspace has become a severe test for network security defense. The root cause of the weak point of attack and defense in the network lies in the deterministic, static and single nature of the network composition...
