Meaning
A trusted third party provides a digital signature that binds a specific time to a piece of electronic data according to an international standard. Every rfc 3161 authority acts as a neutral witness to the existence of a document at a precise moment. It stops being the authority once its digital certificate expires or its security is compromised.
Protocol Standard
Uniform rules ensure that the timestamps produced by different providers are compatible and legally defensible. While the rfc 3161 authority is a technical entity, it follows a rigorous set of procedures to maintain its status. It provides the proof needed for long term archiving of sensitive files.
Cryptographic Stamp
Hashing the document and signing it with a private key creates a seal that is unique to that file and that moment. An rfc 3161 authority ensures that any later modification of the data is immediately obvious to anyone who checks the signature. This provides a high degree of certainty for digital evidence.
External Audit
Oversight from government or industry bodies ensures that the provider maintains the correct time and follows the security script. The use of an rfc 3161 authority moves the burden of proof from the founder to a certified professional. It is the gold standard for temporal evidence in most jurisdictions.
The service is the witness of the record.
