ADSS TSA Server

Trusted Time Stamping

 

Secure Time Stamp Authority (TSA)

ADSS TSA Server provides independent and irrefutable proof of time for transactions, documents and digital signatures. It can be used to create legal weight evidence that business transactions occurred at a defined moment in time, that e-documents existed at a particular time and that they have not been subsequently altered. It can also independently prove when a digital signature was applied by the signer so that its validity can be verified in the long-term, even after expiry or revocation of signer’s digital credentials.

ADSS TSA complies with the IETF RFC 3161 specifications and can be used for internal TSA needs or it can be used to provide infrastructure-class commercial TSA services to multiple external parties. It offers a number of advantages for managed service providers in the authentication, logging/reporting and token management features.
