Abstract: Various embodiments of the present disclosure are directed to a storage device having a non-volatile memory, a Proof of Physical Access (PPA) mechanism and a controller circuit. The PPA mechanism generates a PPA value responsive to a direct physical user interaction with the storage device by a user. In response to receipt of a storage command from a host, the controller circuit executes the received storage command responsive to the storage command being determined to be a protected command and responsive to detection of the PPA value during a predetermined window of time. The controller circuit does not execute the received storage command responsive to the storage command being determined to be a protected command and responsive to an absence of the PPA value during the predetermined window of time. The protected command is a command that changes access to data stored in the non-volatile memory.

Abstract translation: 本公开的各种实施例涉及具有非易失性存储器，物理访问证明（PPA）机制和控制器电路的存储设备。 PPA机制响应于用户与存储设备的直接物理用户交互而产生PPA值。 响应于从主机接收到存储命令，控制器电路响应于确定为保护命令的存储命令并响应于在预定窗口期间检测到PPA值而执行接收到的存储命令。 控制器电路不响应于被确定为受保护命令的存储命令并且响应于在预定窗口期间不存在PPA值而执行接收到的存储命令。 受保护的命令是改变对存储在非易失性存储器中的数据的访问的命令。
