Abstract
A storage system in which a controller has an encryption-related function is provided. There is provided a storage system including an interface section coupled to one or more storages and a controller that carries out reading and writing processes on the storages via the interface section. The controller includes an arithmetic processing section, a memory, and an encryption processing section. The arithmetic processing section causes the memory to hold data before processing and data after processing by the encryption processing section, and limits the access destination from the storages to the memory. The configuration and actions described above allow the storage system to avoid occurrence of deadlock and the controller to have an encryption-related function.
