ISACA CISA Reference: Domain 1 - Information System Auditing Process

A digital signature is a cryptographic technique that uses the sender’s private key to generate a unique code for a message or document. The receiver can use the sender’s public key to verify the authenticity and integrity of the message or document. A digital signature can prevent unauthorized change, as any modification to the message or document will invalidate the signature and alert the receiver of tampering.
