Anonymous Communication in the Browser via Onion-Routing

Every single communication on the Internet reveals private and sensitive information of the communicating parties if no further measures are applied. Various applications and measures are already available to e.g. tunnel traffic through other nodes to obscure the original sender and receiver. Existing frameworks require external applications, running on the particular nodes. We propose a flexible architecture for an anonymous communication framework that supports the interoperability among different platforms. Our proof-of-concept implementation, based on web standards and web technologies shows the feasibility of the framework in terms of usability and interoperability. The framework is running completely in the web-browser and does not have requirements on external applications. The evaluation results show that our framework brings great benefits to user´s privacy and security.
