Application: Information processing system and information processing method (Patent ID: US20240211640A1)
The patent filed by Hitachi Ltd. describes an information processing system that includes a physical drive, a compute unit, and a storage control unit. The storage control unit consists of an IO processing unit and an encryption/decryption-related processing unit. The encryption/decryption-related processing unit is capable of generating a key to encrypt/decrypt data based on key generation method information, which includes elements and algorithms for key generation. This key is then used to encrypt/decrypt data transferred between the compute unit and the physical drive by the IO processing unit.
Furthermore, the patent includes claims detailing the specific functions and capabilities of the information processing system. These claims cover aspects such as generating keys using multiple elements, dividing data into blocks for storage across multiple physical drives, compressing data blocks before encryption, and checking for duplicate data blocks before encryption. The patent also outlines an information processing method for the system, emphasizing the generation of keys, encryption/decryption of data, and the writing or transmission of encrypted/decrypted data by the IO processing unit. Overall, the patent focuses on enhancing data security and efficiency in information processing systems through advanced encryption and key generation methods.
