Method and system for secure distribution of d2d content based on Stein Kohlberg game

Abstract

A method and system for secure distribution of D2D content based on Stan Kohlberg game. In the cellular network, in order to ensure the validity and security of user content sharing, the invention utilizes the fusion of user physical and social information, and based on the Stan-Kolberg game, designs and implements a content security distribution method and system thereof. Among them, in the actual content distribution stage, the content requester needs to select a suitable one or several from many content providers to provide the content it needs, so as to obtain better content sharing services with less cost; and the content Providers also need to determine their distribution plan according to their benefits and costs, so as to provide content sharing services for content requesters with less consumption and security risks, and at the same time obtain more benefits. Therefore, the "leader-follower model" is established by using the Stan-Kolberg game to simulate and realize the optimization of the unit content price φ and the ratio, and obtain the best safe distribution method of D2D content.

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
