  7. Abstract:
  8. Data traffic in communication network has increased steadily in recent years. Service requirements have also changed to become more complex. Moreover decrease in relative prices of computation and storage against communication encourages using more caching in these networks . Meanwhile increased use of encryption in internet has forced service providers who were willing to enter content distribution market to cooperate with content providers. But the cooperation is discouraged by willingness of both parties to hide their internal information. There are solutions proposed for interaction and information exchange between ISPs and CPs which are based on game theory. However, these solutions are not implemented because of practical considerations. Proposed solutions for caching encrypted content without cooperation are immature and not practically feasible. In this thesis we proposed a cooperation model for ISPs and CPs which minimizes the exchange of information. We showed that this model can perform as well as previous models while maintaining privacy of credential information of ISP and CP. Moreover proposed model gives ISPs and CPs control over their own resources prevents disputes over content and network ownership. Further we solved in network cache allocation from the viewpoint of content providers in the proposed model performed simulations and demonstrated that the proposed solution can decrease content provider expenses moderately
