How do digital timestamps support digital signatures?
Answer / Sanjay Kumar Srivastava
Digital timestamps are used to ensure the authenticity and integrity of a digital document by attaching a time-stamp from a trusted third party. This timestamp is then signed by the sender, providing evidence that the document was indeed present at that specific time. Timestamps help maintain non-repudiation in digital signatures.
