SAMSON strong authenticated mail service over NGN

The Universal Postal Union is motivated to develop a new platform: .post, to offer digital services secured from SPAM and cybercriminal activities such as phishing and identity theft. Assuming that strong authentication, network security and QoS must be offered on the international .post platform, the use of national authentication tokens and IMS (IP Multimedia Subsystem) networks is proposed and discussed. A prototype architecture for the .post platform is proposed and the development of an IMS/SIP client to enable the exchange of secured and authenticated mail is described as a sample service to demonstrate the feasibility of the concept.
