-----Original Message----- From: Trevor Perrin [mailto:tre...@trevp.net] Sent: Tuesday, March 18, 2003 10:38 PM To: ds...@lists.oasis-open.org Subject: [dss] Timestamping
[...]
A time-marked signature is just a signature on some content with a signed attribute (created by the signer) containing the signing time.
A time-stamped signature contains, as an unsigned attribute, a timestamp "token", which somehow binds the time and a hash of the time-stamped signature's signatureValue, and is created and signed by a 3rd party TSA (Time Stamp Authority).
My understanding of those two terms is the following:
* A signature is time-marked if the signer claims the signing time and signes this claim together with the actual data.
* A signature is time-stamped if the time is claimed by a trusted third party, and this claim is incorporated into the signature as time stamp token.
Am I right here? Other opinions?
