ISO/IEC JTC 1/SC 27 13888-1:2009 - Non-repudiation - Part 1: General
The goal of a non-repudiation service is to generate, collect, maintain, make available and verify evidence concerning a claimed event or action in order to resolve disputes about the occurrence or non occurrence of the event or action.
Non-repudiation services establish evidence; evidence establishes accountability regarding a particular event or action. The entity responsible for the action, or associated with the event, with regard to which evidence is generated, is known as the evidence subject.
This part of ISO/IEC 13888 serves as a general model for subsequent parts specifying non-repudiation mechanisms using cryptographic techniques. ISO/IEC 13888 provides non-repudiation mechanisms for the following phases of non-repudiation:
— evidence generation;
— evidence transfer, storage and retrieval; and
— evidence verification.
