Dynamic game method and device oriented to internet of things threat-defense resource allocation

Abstract

The invention provides a dynamic game method and device oriented to internet of things threat-defense resource allocation. The optimal allocation of the resources in the internet of things threat-defense can be realized. The method comprises the following steps: constructing an internet of things system risk level function; constructing a target function of minimum defense cost of a defender according to the defense cost, and constructing a target function of the minimum attack cost of an attacker according to the attack cost; and constructing a dynamic game model of the attacker and the defender according to the risk level function, the target function of the minimum defense cost and the target function of the maximum attack cost, and respectively determining the optimal resource allocation values of the attacker and the defender under an opened-loop mode and a closed-loop mode, wherein the opened-loop mode is used for representing a state that the attacker and the defender abide by unchanged established policy at the beginning of the game, and the closed-loop mode is used for representing the dynamic change states of the defender and the attacker after the game is started. The dynamic game method disclosed by the invention relates to the field of internet of things network security.

Description

technical field [0001] The present invention relates to the field of Internet of Things network security, in particular to a dynamic game method and device for resource allocation of Internet of Things threat defense. Background technique [0002] The Internet of Things is a system network containing a large number of nodes, and it is often exposed to complex environments. In addition, most IoT devices are micro-embedded devices with very limited resources. Therefore, compared with traditional network systems, IoT network systems need more effective security protection and threat defense. [0003] However, in the prior art, the problem of resource allocation for IoT threat defense cannot be effectively solved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a dynamic game method and device for resource allocation of Internet of Things threat defense to solve the problem existing in the prior art that cannot eff...
