STORAGE DEVICE, OPERATING METHOD FOR THE SAME AND MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17742164 titled 'STORAGE DEVICE, OPERATING METHOD FOR THE SAME AND MEMORY SYSTEM
Simplified Explanation
The abstract describes a storage device that has improved security performance. The device includes two non-volatile memories - one storing a firmware image and the other storing an emergency image. A storage controller manages these memories and performs various functions.
- The storage controller checks the integrity of the firmware image from the first memory.
- If the integrity check fails, the storage controller loads and executes the emergency image from the second memory.
- The storage controller can receive a recover image from an external device based on the emergency image.
- The recover image is then provided to the first memory.
Potential Applications
- This technology can be applied in various storage devices such as solid-state drives (SSDs), USB drives, or external hard drives.
- It can be used in devices that require high security and reliability, such as military equipment, medical devices, or financial systems.
Problems Solved
- The storage device addresses the problem of compromised firmware by checking the integrity of the firmware image.
- It provides a fail-safe mechanism by loading and executing an emergency image when the firmware image is not secure.
- The ability to receive a recover image from an external device allows for easy restoration of the firmware.
Benefits
- Improved security performance ensures that only secure firmware is used.
- The fail-safe mechanism ensures that the device can still function even if the firmware is compromised.
- The ability to receive a recover image simplifies the process of restoring the firmware, reducing downtime and improving efficiency.
Original Abstract Submitted
A storage device with improved security performance is provided. The storage device comprises a first non-volatile memory storing a firmware image, a second non-volatile memory storing an emergency image, and a storage controller controlling the first and second non-volatile memories, wherein the storage controller checks an integrity of the firmware image received from the first non-volatile memory, loads and executes the emergency image from the second non-volatile memory when the integrity check of the firmware image fails, receives a recover image from an external device based on the emergency image, and provides the recover image to the first non-volatile memory.
