Abstract

ISO/IEC 13888 is concerned with non-repudiation. ISO/IEC 13888-1:2009 is a general part which defines a model for non-repudiation mechanisms providing evidence based on cryptographic check values generated using symmetric or asymmetric cryptographic techniques. Non-repudiation mechanisms provide protocols for the exchange of non-repudiation tokens for non-repudiation services. Specific and additional non-repudiation services are described.
