SE

Overview

SE (Security Element) is an innate security IP core of LoongArch processors. It can provide secure, compliant, and standardized encryption capabilities for your applications.

SE devices can be virtualized and attached to VM instances, thus providing secure encryption for VM instances. You can virtualize up to 64 SE devices on the Cloud but we do not recommend that you virtualize more than 24 SE devices in case of reducing the host performance.
