eSE100 - Secure Sensor-to-Ethernet Module, powered by MS500
The eSE100 (Secure Sensor-to-Ethernet module) provides a secured communication channel between sensors and any network servers. The module is powered by MS500, which is one of the most advanced security SoC's in the industry supporting the hardware-based security functions such as hardwired crypto engines, secure storage, and secure booting features. The module is pre-programmed with embedded SSL/TLS which is optimized to receive the full support from the MS500 hardware crypto engines.
