Cyber-Security: Non-Repudiation

Non-Repudiation provides evidence that a given individual took a particular action (such as creating information, sending a message, approving information, and receiving a message).

It is thereby serves as evidence to the sender of information of proof of delivery and, the recipient is provided with proof of the sender's identity.

It is therefore potection against an individual falsely denying having performed a particular action, so neither can later deny having processed the information.
