Embodiment Construction

[0042] The technical solution of the present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0043] The big data in the active distribution network has many types, many dimensions, and a large amount of data, which is of great value to enterprises and users. When performing data services, assuming that the power grid has been attacked, the present invention uses the game idea in game theory Evaluate the potential threats to the system when it is attacked and the cost of the system's response, and then establish a mathematical model of conflicts of interest between the data intrusion detection system and end users in each link of the Energy Internet, and adjust the response strategy in time, so that To achieve the purpose of adaptive intrusion response, combined with the DBSCAN algorithm to screen out the attacked data.

[0044] like figure 2 As described, a data service-oriented adaptive intrusion response game method of t...

Abstract

The invention discloses a data service-oriented adaptive intrusion response game method and a system thereof and is mainly used for solving the network attack self-adaptive response problem for data service. Whether pure strategy Nash equilibrium exists or not is judged by using the method provided by the invention to build a game model of a detection system and a user; and if not, a hybrid strategy of the detection system is set and then a payment function is created between the two to solve an optimal first-order condition, thereby deriving a Nash equilibrium value of optimal response of thetwo parties of the game, and obtaining an optimal response strategy to respond.

Description

technical field [0001] The invention relates to a data service-oriented self-adaptive intrusion response game method and a system thereof, belonging to the field of network security. Background technique [0002] Energy Internet is a comprehensive use of advanced power electronics technology, information technology and intelligent management technology to interconnect a large number of new power network nodes composed of distributed energy collection devices, distributed energy storage devices and various types of loads to achieve energy bidirectional Flowing energy peer-to-peer exchange and sharing network. Energy Internet is a new type of energy architecture that is compatible with traditional power grids, can fully, widely and effectively utilize distributed renewable energy, and meet users' diverse power needs. With the continuous popularization and development of computer networks, intrusions against energy Internet are becoming more and more rampant. As an effective m...
