A D2D content secure distribution method and system based on a Stackelberg game

Abstract

The invention relates to a D2D content secure distribution method and system based on a Stackelberg game. According to the method and the system, in the cellular network, on the basis of ensuring theeffectiveness and the safety of user content sharing, the content safety distribution method and the content safety distribution system are designed and realized by utilizing the fusion effect of physical and social information of a user and based on the Sartan Korberg game. Wherein in an actual content distribution stage, a content requester needs to select one or more proper contents required bythe content requester from a plurality of content providers, so that a better content sharing service is obtained with less cost; And the content provider also needs to determine the distribution scheme according to the revenue and cost of the content provider, so that the content sharing service is provided for the content requester with less consumption and security risk, and more benefits areobtained at the same time. Establishment of a leader- follower model by using a Stemberberg game andcarries out simulation to optimize the unit content price and proportion (shown in the specification), and an optimal D2D content security distribution mode is obtained.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a method and system for securely distributing D2D content based on the Stan-Kolberg game. Background technique [0002] In recent years, with the explosive growth of wireless data traffic, wireless content sharing services are facing many serious challenges, such as the high redundancy of user requests for multimedia content, the huge pressure on base stations, and the severe shortage of wireless resources. However, D2D content sharing technology can take advantage of D2D communication, distribute the pressure of base stations to mobile terminals all over the network, and effectively deal with the above-mentioned challenges through content caching and distribution technology, which has aroused extensive discussion and research in the industry. [0003] However, there are many problems to be solved urgently in the D2D content sharing technology. Most existing studies ...

AI Technical Summary

Problems solved by technology

It is worth noting that in the D2D content sharing scenario, there are generally multiple content providers near the content requester who can provide the desired content. Since these content providers have different information such as location and channel status, different content providers are selected. The threat of eavesdropping faced by the content requester is not exactly the same

Existing models also do not account for this eavesdropping threat
