The objective of this project is to develop a system enabling users to ex- change messages asynchronously. Messages are sent and received through a non-trustworthy central repository, which keeps messages for users until they fetch them. The resulting system is composed by a Rendezvous Point, or Server, and several clients exchanging messages. The system should be designed to support the following security features: • Message confidentiality, integrity and authentication: Messa- ges cannot be eavesdropped, modified or injected by a third party or the server; • Message delivery confirmation: message readers should be able to prove that they have had access to their contents (i.e. have read them); • Identity preservation: There is a direct association between one user and one Portuguese Citizen, and vice-versa, using the Portuguese Citizen Card
