Abstract

Low latency mix networks such as onion routing (Tor), heavily utilize cryptographic operations for transmitting a message to the receiver resulting in substantial computational and communication overhead. To address the performance and security issues of low latency mix networks, we propose a novel anonymous routing scheme called C-Mix. Its design principles are inspired by network coding techniques and the properties of polynomial interpolation. Based on our security analysis and performance evaluations, C-Mix achieves same level of anonymity with comparable computation overhead in comparison to traditional low latency mix networks.
