Term:Non-Repudiation

DoD 8580.02-R

Non-Repudiation - The ability to ensure that a party to a contract or a communication cannot deny the authenticity of their signature on a document or the sending of a message that they originated. DL1.38.

DoDD 8500.01E

Non-Repudiation - Assurance the sender of data 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 data ( reference (i)). E2.1.30.

DoDD 8581.01

Non-Repudiation - Assurance the sender of data is provided with proof of delivery and the recipient is provided with proof of the sender's identity, so neither may later deny having processed the data ( reference (h)). E2.1.30.

DSS Glossary

Non-Repudiation - Assurance that the sender of data is provided with proof of delivery and the recipient is provided with proof of the sender's identity, so that neither can later deny having processed the data. Digital signatures are the current non- repudiation technique of choice for the National Information Infrastructure.

NIST IR 7298

Non-Repudiation - 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. SOURCE: SP 800-53; CNSSI-4009

NIST IR 7298

Non-Repudiation - 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). SOURCE: FIPS 191

NIST IR 7328 Draft

Non-Repudiation - 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. [CNSS Inst. 4009]

NIST IR 7497 Draft

Non-Repudiation - To ensure that information received can be confirmed as having been sent by the apparent sender, and that no reasonable basis exists for claiming that the information came from some other source; and to ensure that the sender can confirm that the intended recipient has received the information."

NIST SP 800-18r1

Non-Repudiation - 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. [CNSS Inst. 4009]

NIST SP 800-32

Non-Repudiation - 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. (NS4009) 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.

NIST SP 800-37

Non-Repudiation - 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. [CNSS Inst. 4009]

NIST SP 800-39 Draft 2

Non-Repudiation - 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. [CNSS Inst. 4009 Adapted]

NIST SP 800-53A

Non-Repudiation - 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. [CNSS Inst. 4009]

NIST SP 800-53r1

Non-Repudiation - 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.

NIST SP 800-53r2

Non-Repudiation - 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. [CNSS Inst. 4009]

NIST SP 800-53r3

Non-Repudiation - 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.

NIST SP 800-57P1

Non-Repudiation - 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 by a third party as having originated from a specific entity in possession of the private key of the claimed signatory.

NIST SP 800-57P2

Non-Repudiation - 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 by a third party as having originated from a specific entity in possession of the private key of the claimed signatory. In a general information security context, 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 (SP800-53).

NIST SP 800-59

Non-Repudiation - Assurance the sender of data 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 data. [CNSS 4009]
