Outcome achieved when the sender of a document is not able to deny sending it.

The inability of one entity involved in a communication to deny having participated in all or part of the communication.

Provides proof of the origin or delivery of data in order to protect the sender against a false denial by the recipient that the data has been received or to protect the recipient against false denial by the sender that the data has been sent.

Ensures that information cannot be disowned.

The inability by the sender of a message to deny having sent the message at a later time. A regular hand-written signature provides a form of non-repudiation. A digital signature provides another.

Assurance to either party in an electronic transaction that the other cannot later deny having agreed to the transaction. The assurance is provided by means of a digital signature.

For e-Commerce and other electronic transactions, including ATMs (cash machines), all parties to a transaction must be confident that the transaction is secure; that the parties are who they say they are (authentication), and that the transaction is verified as final. Systems must ensure that a party cannot subsequently repudiate (reject) a transaction. To protect and ensure digital trust, the parties to such systems may employ Digital Signatures, which will not only validate the sender, but will also 'time stamp' the transaction, so it cannot be claimed subsequently that the transaction was not authorised or not valid etc.

Provide proof of the origin such that the sender cannot deny sending the message, and the recipient cannot deny the receipt of the message.

a requirement that the sender and recipient of a message can validate their role in the transmission of data. (p. 149)

Assurance that the sender is provided with proof of delivery and that the recipient is provided with proof of the sender's identity so that neither can later deny having processed the data. Technical non-repudiation refers to the assurance a Relying Party has that if a public key is used to validate a digital signature, that signature had to have been made by the corresponding private signature key. Legal non-repudiation refers to how well possession or control of the private signature key can be established.

This term has been the subject of much dispute. Broadly speaking, it is a process that prevents a party to a communication from subsequently denying that the communication took place, or from denying the content of the communication. Sometimes this term is used in a purely technical sense (e.g. generation of data that is dependent on the communication and its content) and sometimes in a legal sense (i.e. evidence that could be sustained in a court of law).

Guarantee that a sender cannot falsely deny having sent a message. Non-repudiation is an essential role of cryptography systems.

The Trusted Time time-stamp creates an evidentiary trail to a reliable time source that prevents a party in a transaction from later denying when the transaction took place.

Process by which a customer cannot deny having paid for an order after it is conducted.

The opposite of repudiation; repudiation, only not

Incontestable proof of the origin, delivery, submission, or transmission of a message.

Steps taken by an agency to provide assurance, via the use of an audit trail, that a sender cannot deny being the source of a message, and that a recipient cannot deny receipt of a message.

Cryptographic assurance that a message sender cannot later deny sending a message, or that the recipient cannot deny receipt

Ensuring that a message has been sent and received by the parties who are claiming to have sent and received it and ensuring the neither party can deny this at a later date.

Method by which the sender of data is provided with proof of delivery and the recipient is assured of the sender's identity, so that neither can later deny having processed the data. [INFOSEC Glossary

A quality where a third party can prove that a communication between two other parties took place. Non-repudiation is desirable if you want to be able to trace your communications and prove that they occurred. See also repudiation.

This prevents individuals from denying that they were involved in a particular electronic transaction.

A service that provides proof of the integrity and origin of data, both in an non-forgeable relationship, which can be verified by any third party at any time, or, an authentication that with high assurance can be asserted to be genuine. A property achieved through cryptographic methods which prevents an individual or entity from denying having performed a particular action related to data (such as mechanisms for non-rejection or authority (origin); for proof of obligation, intent, or commitment, or for proof of ownership).

The property of a receiver being able to prove that the sender of some data did in fact send the data even though the sender might later deny ever having sent it.

Uncontestable proof ot he origin, delivery, submission, or transmission of a message.

a security service which prevents the receiver of a message from denying that the message had been received . n-line publication see On-line resource.

Security service that prevents an entity involved in a data exchange from denying that it participated in the exchange.

The service which provides protection from an individual denying sending information (non-repudiation with proof of origin), or protection from an individual denying receiving information (non-repudiation with proof of delivery). These services are closely related to signing and notarization.

The inability to deny having signed a transaction or file.

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 of a cryptosystem. Non-repudiation cryptosystems are those in which the users cannot deny actions they performed.

Part of the security process that establishes that a message has effectively been sent and received.

Non-repudiation is the concept of ensuring that a contract cannot later be denied by either of the parties involved. Non-repudiation is the opposite of plausible deniability.
