Information technology - Open Systems Interconnection - Security frameworks for open systems: Non-repudiation framework
 N CAN/CSA-ISO/IEC 10181-4-00

Annotation

This Recommendation I International Standard addresses the application of security services in an Open Systems environment, where the term "Open Systems" is taken to include areas such as Database, Distributed Applications, Open Distributed Processing and OSI. The Security Frameworks are concerned with defining the means of providing protection for systems and objects within systems, and with the interactions between systems. The Security Frameworks are not concerned with the methodology for constructing systems or mechanisms.

The Security Frameworks address both data elements and sequences of operations (but not protocoi elements) which are used to obtain specific security services. These security services may apply to the communicating entities of systems as well as to data exchanged between systems, and to data managed by systems.

This Recommendation ] International Standard:

- defines general Non-repudiation services;

- defines the basic concepts of Non-repudiation;

- identifies possible mechanisms to provide the Non-repudiation services;

- identifies general management requirements for Non-repudiation services and mechanisms.

As with other security services, Non-repudiation can only be provided within the context of a defined security policy for a particular application. The definitions of security policies are outside the scope of this Recommendation I International Standard.

The scope of this Recommendation 1 International Standard does not include specification of details of the protocol exchanges which need to be performed in order to achieve Non-repudiation.
