1. An electronic device for performing permission management of a storage device, the storage device comprising multiple storage blocks, the electronic device comprising:
a controller, configured to perform access control of the storage device; and
multiple dedicated interfaces, coupled to multiple ports of the controller, wherein the multiple dedicated interfaces correspond to the multiple storage blocks, each dedicated interface of the multiple dedicated interfaces is configured to provide a dedicated channel for accessing one of the multiple storage blocks corresponding to said each dedicated interface via the controller, the multiple dedicated interfaces and the multiple storage blocks are corresponding to each other one by one, and, different storage blocks of the multiple storage blocks have different address mapping;
wherein the controller assigns multiple hardware unique keys (HUKs) to the multiple dedicated interfaces, respectively, different HUKs of the multiple HUKs are assigned to different dedicated interfaces of the multiple dedicated interfaces, and the controller utilizes a HUK assigned to a first dedicated interface of the multiple dedicated interfaces to control access of a first storage block of the multiple storage blocks corresponding to the first dedicated interface.
