digital signature

Abbreviation(s) and Synonym(s): Definition(s):

  The result of a cryptographic transformation of data that, when properly implemented, provides the services of: 1. origin authentication, 2. data integrity, and 3. signer non-repudiation.
Source(s):
CNSSI 4009-2015 (FIPS 140-2 - NIST SP 800-57 Part 1 Rev 3 )

  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.
Source(s):
NIST SP 800-63-2 under Digital Signature [Superseded]

  The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, assurance of data integrity and signatory non-repudiation.
Source(s):
NIST SP 800-102 under Digital signature
NIST SP 800-133 under Digital signature

  The result of a cryptographic transformation of data that, when properly implemented with a supporting infrastructure and policy, provides the services of: 1. Origin authentication, 2. Data integrity, and 3. Signer non-repudiation.
Source(s):
NIST SP 800-152 under Digital signature

  The output that results from the successful completion of a digital signature algorithm operating on data (e.g., a message) that is to be signed. When used appropriately, a digital signature can provide assurance of data integrity, origin authentication, and signatory non-repudiation. See [FIPS 186-3] for details.
Source(s):
NIST SP 800-106 under Digital signature

  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)

  The result of a cryptographic transformation of data that, when properly implemented with a supporting infrastructure and policy, provides the services of: 1. Origin (i.e., source) authentication, 2. Data integrity authentication, and 3. Support for signer non-repudiation.
Source(s):
NIST SP 800-57 Part 1 Rev. 4 under Digital signature

  The result of applying two cryptographic functions (a hash function, followed by a digital signature function; see FIPS 186-3 for details). When the functions are properly implemented, the digital signature provides origin authentication, data integrity protection and signatory non-repudiation.
Source(s):
NIST SP 800-107 Rev. 1 under Digital signature

  The result of a cryptographic transformation of data that, when properly implemented with a supporting infrastructure and policy, provides the services of: 1. Origin authentication, 2. Data integrity, and 3. Signer non-repudiation.
Source(s):
NIST SP 800-57 Part 1 Rev. 3 under Digital signature [Superseded]

  The result of a cryptographic transformation of data that, when properly implemented, provides the services of: 1. origin authentication 2. data integrity, and 3. signer non-repudiation.
Source(s):
NIST SP 800-57 Part 2 under Digital signature

  The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, data integrity and signatory non-repudiation.
Source(s):
NIST SP 800-89 under Digital signature

  a data unit that allows a recipient of a message to verify the identity of the signatory and integrity of the message.
Source(s):
NIST SP 800-15

  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.
Source(s):
NIST SP 800-32 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, but not confidentiality protection.
Source(s):
NIST SP 800-63-3 under Digital Signature

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