Qualified Timestamping Server TSA
With built-in HSM Hardware Security Module
Elproma TSA ensures the tamper-proof creation and authenticity of timestamps. It is the ideal Hardware Security Module (HSM) network appliance for business applications that require proving the existence and status of a document or data at a specific point in time. The timestamp server (TSA) ensures that timestamped data is authentic for these and similar applications. Timestamps are able to verify at all times, whether or not the timestamped data matches the exact same form at the point in time it was logged by the timestamp.
Furthermore, the timestamps (if survive over time longer than TSA) are still able to be verified without TSA authenticating for data (document file or data streaming):
- Originality of any document, video streaming, picture etc.
- Integrity – say nothing can be changed since the moment of data sealing
- Non-repudiation of chronology – proving existence in a moment of history
