Definition
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 data authentication and integrity protection.
Alternative Definitions
- Definition 2
A cryptographic operation where a private key is used to digitally sign an electronic document and the associated public key is used to verify the signature.
- Definition 3
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.
- Definition 4
A value computed with a cryptographic process using a private key and then appended to a data object, thereby digitally signing the data.
- Definition 5
A cryptographic operation where a private key is used to digitally sign an electronic document and the associated public key is used to verify the signature. Digital signatures provide data authentication and integrity protection.
- Definition 6
A bitstring attached to a document that is a f unction both of the document and the signer. It consists of a digest of the document encrypted with a private cryptographic key belonging to the signer. Through the use of digital signa tures both the identity of the signer and the integrity of the document can be verified. A digital signature is a particular form of ELECTRONIC SIGNATURE.
