Abstract : In this thesis, we present different systems providing low-latency anonymous communications. We first study the performance of systems based on well known primitives such as superposed sending and encrypted padding for transmission, and broadcast with implicit addressing for reception, when the group of potential users is restricted to be small, closed, or localized. We propose the usage of Private Information Retrieval (PIR) protocols as an alternative to broadcast with implicit addressing, and we study the resulting systems. These systems allow us to trade communication cost, for computational cost. Through some examples, we show that the new solutions offer a better choice in some situations, specially when the users are connected to the service through the Internet. Then, we put forward how the different approaches are related, and show that the systems based on classic primitives are in fact just some instances of a family, which becomes much larger and versatile through the introduction of PIR protocols.
