- Digital Signature
Definition of "Digital Signature"
- A digital signing algorithm is a process by which a user can produce a short string of data called a “signature” on a document, using a private key. Anyone with the corresponding public key, the signature, and the document can verify that (1) the document was “signed” by the owner of that particular private key, and (2) the document was not changed after it was signed. Note that this differs from traditional signatures which are more susceptible to tampering. With a digital signature, any change to the document will invalidate the authorization.
