Abstract

The problem of anonymous authentication, which is key to preserving the privacy of users, has an increased relevance given the proliferation of applications that use components deployed in the network, that cannot be fully trusted. A possible strategy to preserve user privacy is to implement authentication using pseudonyms. In this thesis, we survey how pseudonyms have been used to protect privacy in different application areas and discuss the advantages and limitations of the different approaches to managing pseudonyms. Based on the limitations of previous work, we design, implement, and evaluate novel techniques to enhance the performance of systems that use pseudonyms.
