| 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.
This non-repudiation control enhancement is intended to mitigate the risk that information gets modified between production and review. The validation of bindings can be achieved, for example, by the use of cryptographic checksums.
When the identity of the producer of a piece of information is not bound to the information, the validity of the information can be questioned or the producer of the information can deny having produced it. |
