This paper provides a formal framework for the analysis of information hiding properties of anonymous communica- tion protocols in terms of epistemic logic. The key ingre- dient is our notion of observational equivalence, which is based on the cryptographic structure of messages and re- lations between otherwise random looking messages. Two runs are considered observationally equivalent if a spy can- not discover any meaningful distinction between them. We illustrate our approach by proving sender anonymity and unlinkability for two anonymizing protocols, Onion Rout- ing and Crowds. Moreover, we consider a version of Onion Routing in which we inject a subtle error and show how our framework is capable of capturing this flaw. |
