Programmable secure management device and control method for performing key forwarding between secure devices

Abstract

A programmable secure management device and a control method for performing key forwarding between secure devices are provided. The programmable secure management device includes a key generating device, a key accepting device and a forwarding controller circuit, wherein the forwarding controller circuit is electrically coupled to the key generating device and the key accepting device. The key generating device is configured to output a source key, and the key accepting device is configured to accept a destination key, wherein the forwarding controller circuit is configured to receive a forwarding command from a host device outside the programmable secure management device, to allow the host device to request the forwarding controller circuit via the forwarding command for taking the source key as the destination key to be loaded in the key accepting device.
