CNSSI 4009

Digital Signature - Cryptographic process used to assure message originator authenticity, integrity, and nonrepudiation. Synonymous with electronic signature.

FIPS 140-2

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.

GAO-09-232G

Digital Signature - Cryptographic process used to assure message originator authenticity, integrity, and nonrepudiation.

NIST IR 7298

Digital Signature - A nonforgeable transformation of data that allows the proof of the source (with nonrepudiation) and the verification of the integrity of that data. SOURCE: FIPS 196

NIST IR 7298

Digital Signature - An asymmetric key operation where the private key is used to digitally sign an electronic document and the public key is used to verify the signature. Digital signatures provide authentication and integrity protection. SOURCE: SP 800-63

NIST IR 7298

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: FIPS 140-2

NIST SP 800-102

Digital Signature - The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, assurance of data integrity and signatory non- repudiation.

NIST SP 800-106

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.

NIST SP 800-107

Digital Signature - The result of applying two cryptographic functions (a cryptographic hash function, followed by a digital signature function, see [FIPS 186-3] for details) to data that, when the functions are properly implemented, provides origin authentication, data integrity and signatory non- repudiation.

NIST SP 800-116

Digital Signature - A data object produced by a digital signature method, such as Rivest, Shamir, Aldeman (RSA) or the Elliptic Curve Digital Signature Algorithm (ECDSA), that when verified provides strong evidence of the origin and integrity of the signed data object.

NIST SP 800-32

Digital Signature - 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.

NIST SP 800-57P1

Digital Signature - The result of a cryptographic transformation of data that, when properly implemented with supporting infrastructure and policy, provides the services of:

1. origin authentication
2. data integrity, and
3. signer non- repudiation.

NIST SP 800-57P2

Digital Signature - 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.

NIST SP 800-63v1.0.2

Digital Signature - An asymmetric key operation where the private key is used to digitally sign an electronic document and the public key is used to verify the signature. Digital signatures provide authentication and integrity protection.

NIST SP 800-89

Digital Signature - The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, data integrity and signatory non- repudiation.
