Signature (digital)

Perform a cryptographic calculation using a message, a signature for the message, and a public key, to determine whether the signature was generated by someone knowing the corresponding private key.

A method for ensuring a recipient that a message truly came from the claimed sender and that the message was not altered while in transit between the sender and recipient. Cryptographic process used to assure message originator authenticity, integrity, and nonrepudiation. Synonymous with electronic signature. The act of electronically affixing an encrypted message digest to a computer file or message in which the originator is then authenticated to the recipient.

Any technique designed to provide the electronic equivalent of a handwritten signature to demonstrate the origin and integrity of specific data. Digital signatures are an example of electronic signatures. See digital signature.

This is an information system utilizing an algorithm or series of algorithms which provide a cryptographic key pair consisting of a private key and a corresponding public key. The keys of the pair have the properties that (1) the public key can verify a digital signature that the private key creates, and (2) it is computationally infeasible to discover or derive the private key from the public key. The public key can therefore be disclosed without significantly risking disclosure of the private key. This can be used for confidentiality as well as for authentication.
