Abstract: This application relates to the field of storage technology and discloses a method for protecting partial space of SSD and a storage system. The storage space of the SSD is divided into multiple regions and there is a partition table stored in the SSD, which includes region type of each region. The method includes: receiving, by the SSD, a command to read the partition table; and retrieving, by the SSD, the partition table, removing one or more regions with the region type being locked from the partition table, and returning the removed partition table. This application provides a simple implementation and self-encrypting protection scheme, which requires fewer running resources, is easy to operate, has strong portability, and can meet basic self-encrypting and locking requirements.

Abstract: The present disclosure relates to a firmware security verification method and device, including a processor and a read-only memory for storing instructions executable by the processor. While executing the instructions, the processor implements the following steps: acquiring firmware data and a digital signature; verifying the digital signature with a pre-stored public key; and running the firmware data upon determining that the digital signature passes the verification. With the firmware security verification method and device provided in embodiments of the present disclosure, the security of the firmware data can be acquired before the running of firmware.
