An efficient privacy-preserving routing protocol USOR (Unobservable Secure On-demand Routing) that achieves content un-observability by employing anonymous key establishment based on group signature. The setup of USOR is simple: in privacy-preserving communications can largely be divided into two categories: cryptosystem-based techniques and broadcasting-based techniques. The cryptosystem-based techniques include mix-based systems and secure multiparty computation-based systems, originating from mix net and DC-net respectively. Broadcasting based schemes provide communication privacy by mixing the real messages with dummy packets so that it is infeasible for the adversaries to identify the real packets and track the message source.
