2.44 eSignature / Digital signature

Result of a cryptographic transformation of data that, when properly implemented with supporting infrastructure and policy, provides for a digital message or document the services of origin authentication, data integrity and signer non-repudiation.


A valid eSignature gives a recipient reason to believe that the message was created by a known sender, such that the sender cannot deny having sent the message (digital authentication and non-repudiation) and that the message was not altered in transit (data integrity).
