Privacy enhanced electronic mail

The progress of work at University College of London in implementing a prototype model of a privacy-enhanced messaging (PEM) system is reported. The design of model is specified by the DARPANET IAB Privacy Task Force RFC 1040. The model is one which provides privacy, integrity, and authentication of messages transmitted in a typical electronic-mail system. The design and implementation experience of the prototype model is set out and several potential refinements to the model are suggested for future development.<
