ProtectServer Internal Express 2 (PSI-E2)

Certificate

Module description

The Thales PSI-E 2 is a high-end intelligent PCI adapter card, used either standalone or in the Thales PSE 2 appliance, that provides a wide range of cryptographic functions using firmware and dedicated hardware processors. The module provides key management (e.g., generation, storage, deletion, and backup), an extensive suite of cryptographic mechanisms, and process management including separation between operators. The PSI-E 2 also features non-volatile tamper protected memory for key storage, a hardware random number generator, and an RTC.
