  "definition": "1. The result of a cryptographic transformation of data that, when properly implemented, provides a mechanism for verifying origin authentication, data integrity, and signatory non-repudiation.\n\n2. The result of a cryptographic transformation of data that, when properly implemented, provides a mechanism to verify origin authenticity and data integrity and to enforce signatory non-repudiation.\n\n3. An asymmetric key operation in which 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 support but not confidentiality or replay attack protection.\n\n4. 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.\n\n5. 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.\n\n6. 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.\n\n7. The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, assurance of data integrity and signatory non-repudiation.\n\n8. 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.\n\n9. 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.\n\n10. a data unit that allows a recipient of a message to verify the identity of the signatory and integrity of the message.\n\n11. The result of a cryptographic transformation of data that, when properly implemented with a supporting infrastructure and policy, provides the services of:\n1. Origin authentication,\n2. Data integrity, and\n3. Signer non-repudiation.\n\n12. 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.\n\n13. The result of a cryptographic transformation of data that, when\nproperly implemented, provides the services of:\n1. origin authentication\n2. data integrity, and\n3. signer non-repudiation.\n\n14. The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, data integrity and signatory non-repudiation.\n\n15. The result of a cryptographic transformation of data that, when properly implemented, provides the services of: 1. Source/entity authentication, 2. Data integrity authentication, and/or 3. Support for signer non-redudiation.\n\n16. The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, assurance of data integrity and supports signatory nonrepudiation.\n\n17. The result of a cryptographic transformation of data that, when properly implemented with a supporting infrastructure and policy, provides the services of:\n1. Origin (i.e., source) authentication,\n2. Data integrity authentication, and\n3. Support for signer non-repudiation.\n\n18. The result of a cryptographic transformation of data that, when properly implemented, provides the services of 1. Source authentication, 2. Data integrity, and 3. Support for signer non-repudiation.\n\n19. The result of a cryptographic transformation of data that, when properly implemented with a supporting infrastructure and policy, provides the services of: 1. Source/identity authentication, 2. Data integrity authentication, and/or 3. Support for signer non-repudiation.\n\n20. The result of a cryptographic transformation of data that, when properly implemented, provides source authentication, assurance of data integrity, and supports signatory non-repudiation.\n\n21. The result of a cryptographic transformation of data that, when properly implemented, provides origin authentication, assurance of data integrity, and signatory non-repudiation.\n\n22. The result of a cryptographic transformation of data that, when properly implemented, provides the services of origin authentication, data integrity, and signer nonrepudiation.\n\n23. A cryptographic technique that utilizes asymmetric-keys to determine authenticity (i.e., users can verify that the message was signed with a private key corresponding to the specified public key), non-repudiation (a user cannot deny having sent a message) and integrity (that the message was not altered during transmission).\n\n24. 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.\n\n25. 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.",
