STORAGE SYSTEM AND CRYPTOGRAPHIC OPERATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18138793 titled 'STORAGE SYSTEM AND CRYPTOGRAPHIC OPERATION METHOD

Simplified Explanation

The patent application describes a storage system that can perform different types of cryptographic operations.

• The system includes a cryptographic operation circuit that encrypts data based on the format determined by the processor.
• The encrypted data can be decrypted by the circuit based on the format determined by the processor.
• The system is designed to support various cryptographic operation formats.
• The operations are performed in response to requests from a host terminal for writing or reading data from the storage device.

Original Abstract Submitted

A storage system that can achieve a cryptographic operation circuit that supports multiple types of cryptographic operation formats. The cryptographic operation circuit is provided that encrypts data according to the format determined by the processor based on a request by the host terminal for writing the data into the storage device, and decrypts the encrypted data on the data stored in the storage device according to the format determined by the processor based on a request by the host terminal for reading the data from the storage device.
