Timestamp Server is part of a new generation of Public Key Infrastructure (PKI) components designed to meet the complex requirements of today's enterprise. The ability to be able to prove the time and date that a contract was signed, or that a fund was transferred, is of the utmost importance in e-Commerce.
The purpose of the Timestamp Server is to respond to a request for a signed time stamp from a remote client. Typically, this time stamp will be used to provide unforgeable evidence of a particular document at a particular point in time. To achieve this, the time stamp must be irrevocably tied to the document itself using a hash value of the document, and must be signed by a trusted authority - the Time Stamp Authority.
Timestamp Server runs on Windows NT and offers a complete system for the issuance of timestamps. In summary, UniCERT Timestamp Server:
- supports RSA (2048) and DSA (1024) keys;
- is X.509 standards compliant;
- supports multiple independent timestamping services (Time Stamp Authorities) on the same machine, each of which can use different signing keys and implement different timestamp issuing policies;
- supports an extendable set of different UTC time sources e.g. the system clock, NTP or GPS;
- can use hardware security modules to perform its cryptographic operations;
- maintains comprehensive and secure transaction and audit logs;
- comes complete with a client application kit, which allows you to integrate timestamp requests into your own applications;
- includes a fully functional demonstration application;
- works with any standards-based Certificate Authority, including Baltimore's UniCERT Version 3.1.2 (accredited to ITSEC E3).
