Abstract
Whether a connected drive is an unauthorized drive or not can be judged before it becomes possible for the connected drive to access a memory for a storage controller. When a storage device is connected, an information processing apparatus forms a first communication channel via a first interface incapable of accessing a built-in memory even when the communication connection is established; and a second communication channel via a second interface capable of accessing the built-in memory when the communication connection is established. At a specified timing when the communication connection via the second communication channel is not established, a processor executes authenticity verification processing for verifying authenticity of the storage device on the basis of information acquired from the storage device by using the first communication channel and permits establishment of the communication connection via the second communication channel when the authenticity is confirmed by the authenticity verification processing.
