TuffServ® Encryption Module (TSEM)
Ampex Data Systems Corporation - FIPS 140 #4938
The Ampex TSEM hardware module provides two inline (“bump in the wire”) SATA encryptors running at 6Gbps. The paired encryptors support line rate performance with a very modest latency penalty. Using an intelligent secure microcontroller, the TSEM imposes few requirements or dependencies on the host platform, facilitating rolling software patches and without compromising the system design. The module is designed to operate over the industrial temperature range (components rated -40 to +85) and requires a dedicated carrier board to support cooling and physical security.
