STORAGE DEVICE, STORAGE SYSTEM OPERATING METHOD, AND COMPUTING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17872180 titled 'STORAGE DEVICE, STORAGE SYSTEM OPERATING METHOD, AND COMPUTING SYSTEM
Simplified Explanation
The abstract describes a storage device that uses a non-volatile memory and a memory controller to encrypt plaintext data and store it in the memory. The encrypted data, known as homomorphic ciphertext, is provided to a host upon request. The innovation lies in the fact that the homomorphic ciphertext is generated with a specific level, and the device ensures that the ciphertext with the first level has the smallest length among all the different levels.
- The storage device includes a non-volatile memory and a memory controller.
- The memory controller encrypts plaintext data to create homomorphic ciphertext.
- The homomorphic ciphertext is generated with a specific level.
- The device stores the homomorphic ciphertext with the first level in the non-volatile memory.
- The device provides the homomorphic ciphertext with the first level to a host upon request.
- The homomorphic ciphertext with the first level has the smallest length among all the different levels.

Original Abstract Submitted
A storage device includes a non-volatile memory, and a memory controller, wherein the memory controller encrypts plaintext to generate a homomorphic ciphertext with a first level among homomorphic ciphertexts with different levels, stores the homomorphic ciphertext with the first level in the non-volatile memory, and provides the homomorphic ciphertext with the first level in response to a request received from a host. The homomorphic ciphertext with the first level has a smallest length among the homomorphic ciphertexts with different levels.
