A survey on protocol based control system to enhance internet censorship

VPN (Virtual Private Network) is a mechanism that creates a private network inside a public network (such as the internet) to transfer data. The VPN creates a virtual tunnel within a public network and uses various encryption techniques to keep the transmitted data safe. Though the VPN was created to increase security on a public network, this also masks the user’s true identity on the internet making them virtually anonymous. Thus, VPN introduces some new cyber security issues. In this paper, we will look at some of the existing methods to prevent the usage of VPN, and their weaknesses. We will also understand the proposed system of Content Restriction Protection Protocol (CRPP), how it works and how it overcomes the weakness of the existing methods.
