Nonrepudiation is the integrity of the data to be true to its origin, which prevents possible denial that an action occurred. [3] [1] Increasing non-repudiation makes it more difficult to deny that the information comes from a certain source. In other words, it making it so that you can not dispute the source/ authenticity of data.
Note: In addition, other properties, such as authenticity, accountability, non-repudiation and reliability can also be involved." (ISO/IEC 27000:2018) [ 17 ] "The protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction in order to provide confidentiality, integrity ...
In law, non-repudiation is a situation where a statement's author cannot successfully dispute its authorship or the validity of an associated contract.

Alice signs a message—"Hello Bob!"—by appending a signature which is computed from the message and her private key. Bob receives both the message and signature.

Integrity; Authenticity; Availability; Utility; These attributes of information are atomic in that they are not broken down into further constituents; they are non-overlapping in that they refer to unique aspects of information. Any information security breach can be described as affecting one or more of these fundamental attributes of information.
In cryptography, a message authentication code (MAC), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity-checking a message. In other words, it is used to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity).
In reference to digital security, non-repudiation means to ensure that a transferred message has been sent and received by the parties claiming to have sent and received the message. Non-repudiation is a way to guarantee that the sender of a message cannot later deny having sent the message and that the recipient cannot deny having received the ...
"Security" is a new characteristic with subcharacteristics of "confidentiality" (data accessible only by those authorized), "integrity" (protection from unauthorized modification), "non-repudiation" (actions can be proven to have taken place), "accountability" (actions can be traced to who did them), and "authenticity" (identity can be proved ...
