MEMORY CONTROLLER AND STORAGE DEVICE INCLUDING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18186203 titled 'MEMORY CONTROLLER AND STORAGE DEVICE INCLUDING SAME

Simplified Explanation

The present disclosure describes a storage device with a memory device that has a namespace divided into zones, a cache memory storing media encryption keys for different key tags, an encryptor that encrypts data based on a media encryption key corresponding to a key tag in a write command from a host, and a write operation controller that stores the encrypted data in the memory device. The media encryption key is generated using a first media encryption key from the host and a Root of Trust (RoT) from the encryptor.

  • Memory device with zones in namespace
  • Cache memory storing media encryption keys for key tags
  • Encryptor encrypting data based on key tag in write command
  • Write operation controller storing encrypted data in memory device
  • Media encryption key generated from first media encryption key and RoT

Potential Applications

This technology could be applied in secure data storage systems, cloud storage services, and data centers where data encryption and protection are crucial.

Problems Solved

This technology solves the problem of securing data during storage and transfer by encrypting it with unique media encryption keys based on specific key tags.

Benefits

Original Abstract Submitted

The present disclosure relates to a storage device including a memory device to which a namespace including a plurality of zones is applied, a cache memory caching a media encryption key corresponding to each of a plurality of key tags, an encryptor encrypting data subject to a write request in response to a command input from a host by using a media encryption key corresponding to a key tag included in the command, and outputting encrypted data, and a write operation controller controlling the memory device to store the encrypted data in the memory device, wherein the media encryption key is a second media encryption key generated based on a first media encryption key provided from the host and a Root of Trust (RoT) generated from the encryptor.
