nonrepudiation

Legal non-repudiation refers to how well possession or control of the private signature key can be established.

Non-repudiation: The receiver can prove that the sender actually sent the message.

In law, non-repudiation implies one's intention to fulfill their obligations to a contract.

Digital signature schemes can be used for sender authentication and non-repudiation.

When properly handled, private signature keys can be used to provide authentication, integrity and non-repudiation.

This implies that IBE systems cannot be used for non-repudiation.

Thus, digital signatures do offer non-repudiation.

The security model therefore offers confidentiality and authentication, but limited authorization capabilities, and no non-repudiation.

The standard method for non-repudiation is to write transactions to an audit trail that is subject to specific security safeguards.

Security Layer: offering mutual authentication, integrity, confidentiality, non-repudiation.

Electronic commerce uses technology such as digital signatures and public key encryption to establish authenticity and non-repudiation.

Others may be less expensive to implement and have a lower cost of ownership, but many not support authentication, authorization, data integrity and non-repudiation.

Non-repudiation: The recipient should have the ability to prove to a third party (e.g. a judge) that the sender has sent the signcrypted text.

Integrity: Guarding against improper information modification or destruction, and includes ensuring information non-repudiation and authenticity.

This electronic proof, postmarked by the Postal Service, provides evidence to support non-repudiation of electronic transactions.

Such additional properties mainly include: Confidentiality, Unforgeability, Integrity, and Non-repudiation.

The six basic security concepts that need to be covered by security testing are: confidentiality, integrity, authentication, availability, authorization and non-repudiation.

For non-repudiation a hash function can be applied successively to additional pieces of data in order to record the chronology of data's existence.

There is fairly universal consensus that non-repudiation requires that a private key be under sole control of its owner during its entire lifecycle.

Encryption and digital signature are two fundamental cryptographic tools that can guarantee the confidentiality, integrity, and non-repudiation.

Again, some would add further categories such as non-repudiation and accountability, depending on how narrowly or broadly the CIA Triad is defined.

Non-repudiation, or more specifically non-repudiation of origin, is an important aspect of digital signatures.

LiveCycle Digital Signatures automates electronic signature workflows for added assurances of authenticity, integrity, and non-repudiation.

Cryptography provides information security with other useful applications as well including improved authentication methods, message digests, digital signatures, non-repudiation, and encrypted network communications.

And, the CAC covers the bases for digital signature and data encryption technology: authentication, integrity and non-repudiation.
