STORAGE DEVICE DELETING ENCRYPTION KEY, METHOD OF OPERATING THE SAME, AND METHOD OF OPERATING ELECTRONIC DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240086336 titled 'STORAGE DEVICE DELETING ENCRYPTION KEY, METHOD OF OPERATING THE SAME, AND METHOD OF OPERATING ELECTRONIC DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a method for operating a storage device that communicates with a host device, involving secure data storage and deletion processes.
- Secure region and user region are allocated within the storage device.
- First data is encrypted using a first encryption key and stored in a secure region.
- A request for secure deletion of the first data is received from the host device.
- Valid data from the first data block is decrypted using the first encryption key.
- The decrypted valid data is re-encrypted using a second encryption key.
- The re-encrypted valid data is stored in a different data block within the secure region.
- The first encryption key is deleted.
Potential Applications
The technology described in the patent application could be applied in various industries and sectors, including:
- Data security and encryption
- Cloud storage services

Original Abstract Submitted
disclosed is a method of operating a storage device which communicates with a host device. the method includes allocating a secure region and a user region, storing first data encrypted by using a first encryption key in a first data block of the secure region, receiving a first request indicating a first secure delete operation of the first data from the host device, decrypting at least one valid data of the first data block by using the first encryption key based on the first request, wherein the at least one valid data do not include the first data, encrypting the decrypted at least one valid data by using a second encryption key different from the first encryption key, storing the encrypted at least one valid data in a second data block of the secure region, and deleting the first encryption key.
