(2011/2/18) Europe: Ascertia wins British Library tender for next generation Time Stamp Authority Services
The British Library has selected Ascertia's ADSS TSA Server working with Thales Solo HSMs and Meinberg M300 GPS NTP Servers to provide an effective high volume, resilient, trustworthy source of timestamps to secure the data being ingested into the national Digital Library System. ADSS Server is able to deliver hundreds of SHA-2 RSA-2048 timestamps with time drift checking and alerting using alternative GPS time sources. This confirms Ascertia's dominance in supplying RFC 3161 and ETSI 102 023 compliant TSAs.
