non-repudiation

Non-repudiation is the ability for a system to prove that a specific user and only that specific user sent a message and that it hasn't been modified.

A property achieved through cryptographic methods to protect against an individual or entity falsely denying having performed a particular action related to data.

The assurance that a party cannot later deny originating data; provision of proof of the integrity and origin of the data and that can be verified by a third party Scope Note: A digital signature can provide non-repudiation.

Ensuring 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 message.

Assurance that the sender of information is provided with proof of delivery and the recipient is provided with proof of the sender’s identity, so neither can later deny having processed the information.

Protection against an individual falsely denying having performed a particular action. Provides the capability to determine whether a given individual took a particular action such as creating information, sending a message, approving information, and receiving a message.

Is the security service by which the entities involved in a communication cannot deny having participated. Specifically, the sending entity cannot deny having sent a message (non-repudiation with proof of origin), and the receiving entity cannot deny having received a message (non-repudiation with proof of delivery).

A service that is used to provide assurance of the integrity and origin of data in such a way that the integrity and origin can be verified and validated by a third party as having originated from a specific entity in possession of the private key (i.e., the signatory).
