Abstract (en)
[origin: WO0011828A1] A digital signature certification system creates a nonce and attaches a time to the nonce to create a time stamped nonce uniquely identifying the time stamp then attaches the time stamped nonce to a document, attaches a digital signature to the document, then attaches a time to the document to form a time stamped document, so that the nonce uniquely identifies the signature on the document.
