Fading with the Time

Abstract

Nowadays, most Internet applications are generally faced with various traffic monitoring and content monitoring threats. To protect business secrets and personal privacy, anonymous communication technology has attracted widespread attention. Anonymous communication technology not only provides protection of confidentiality, integrity and availability, but also hides communication relationships and routing information through onion routing and other technologies. Although anonymous communication networks can provide better security and confidentiality, the control plane of most anonymous communication networks still lacks adequate protection mechanisms. For example, the Tor network needs to explicitly download control information from a directory server. This method of obtaining control information exists security risks. This paper proposes a method for obtaining control information of anonymous network based on asynchronous communication. We use the public storage service of the Internet as a transit platform to exchange control information between the user terminal and the control center of the anonymous communication network, and design an automatic destruction mechanism to make the buffered control information on the public platform will not be obtained by third parties. This method is suitable for most anonymous communication networks and can effectively improve the protection of the control plane of anonymous communication networks.
