Abstract
An embodiment of restricted command set management permits a storage controller to execute commands of a restricted command set if authorized. A command determined to be within the restricted command set is encrypted by a host prior to sending the encrypted command to a storage controller for execution. The command may be encrypted using a key shared between the host and the storage controller. The shared key may be generated by the host and encrypted by the host using a public key of a public-private key maintained by the storage controller. The encrypted shared key may be decrypted by the storage controller using the private key of the public-private key maintained by the storage controller. Execution of commands of the restricted command set is prevented absent proper decryption of the commands sent by the host. Other features and aspects may be realized, depending upon the particular application.
