Abbreviation(s) and Synonym(s):

Digital Signature

Definition(s):

  The result of a cryptographic transformation of data which, when properly implemented, provides the services of: 1. origin authentication, 2. data integrity, and 3. signer non-repudiation.
Source(s):
NIST SP 800-12 Rev. 1 under Digital Signature FIPS 140-2

  An asymmetric key operation where the private key is used to digitally sign data and the public key is used to verify the signature. Digital signatures provide authenticity protection, integrity protection, and non-repudiation, but not confidentiality protection.
Source(s):
NIST SP 800-63-3 under Digital Signature
NISTIR 8011 Vol. 3 under Digital Signature NIST SP 800-63

  The result of a transformation of a message by means of a cryptographic system using keys such that a Relying Party can determine: (1) whether the transformation was created using the private key that corresponds to the public key in the signer’s digital certificate; and (2) whether the message has been altered since the transformation was made.

  The result of a cryptographic transformation of data that, when properly implemented, provides the services of origin authentication, data integrity, and signer nonrepudiation.

NISTIR 7316 under Digital Signature

  An asymmetric key operation where the private key is used to digitally sign data and the public key is used to verify the signature. Digital signatures provide authenticity protection, integrity protection, and non-repudiation.
