Description
Without non-repudiation, it is impossible to positively attribute an action to an individual (or process acting on behalf of an individual).
Non-repudiation services can be used to determine if information originated from a particular individual, or if an individual took specific actions (e.g., sending an email, signing a contract, approving a procurement request) or received specific information. Non-repudiation protects individuals against later claims by an author of not having authored a particular document, a sender of not having transmitted a message, a receiver of not having received a message, or a signatory of not having signed a document. The application will be configured to provide non-repudiation services for an organization-defined set of commands that are used by the user (or processes action on behalf of the user).
DoD PKI provides for non-repudiation through the use of digital signatures. Non-repudiation requirements will vary from one application to another and will be defined based on application functionality, data sensitivity and mission requirements.
