Scope

This document establishes a generic structure for non-repudiation services, as well as several specific non-repudiation mechanisms for providing non-repudiation of origin (NRO) and non-repudiation of delivery (NRD). This document is applicable to the design, implementation and testing of applications related to message non-repudiation realized by symmetric technology.
