Engineering Contradiction Analysis
1Reliability
If cryptographic operations are performed on encrypted database using general processing unit, then data security is maintained, but processing speed and computational efficiency deteriorate due to high computing overheads
Solution Approach 1:
The system segments the processing unit into a general processing unit (first computing unit) that handles data security and cryptographic operations, and a dedicated acceleration unit (second computing unit) that handles computational tasks. This segmentation allows cryptographic operations to be isolated on the general processing unit while computationally intensive tasks are offloaded to the acceleration unit, resolving the contradiction between maintaining security and improving processing speed.
Solution Approach 2:
The patent introduces a database management system as an intermediary that coordinates between the general processing unit and the dedicated acceleration unit. The DBMS manages the distribution of cryptographic operations and computational tasks, enabling the system to maintain security requirements while leveraging the acceleration unit for improved processing performance.
2Reliability
If cryptographic operations are performed on encrypted database, then data protection is achieved, but computing time increases significantly
Solution Approach 1:
The patent extracts computationally intensive cryptographic operations from the general processing unit and relocates them to a dedicated acceleration unit. This extraction allows the general processing unit to focus on security-critical cryptographic functions while the acceleration unit handles time-consuming computational tasks, thereby reducing overall computing time without compromising data protection.
Solution Approach 2:
The system dynamically assigns cryptographic operations between the general processing unit and the dedicated acceleration unit based on task requirements. The database management system dynamically determines which unit should execute specific cryptographic operations, enabling flexible resource allocation that optimizes both data protection and computing time efficiency.

AI summary
A data processing method for an encrypted database is performed by a heterogeneous processing platform including a first computing unit implemented by a general processing unit and a second computing unit implemented by a dedicated acceleration unit. The method includes: obtaining, by the first computing unit, a ciphertext parameter and a database instruction from a user end device, where the database instruction instructs to perform a target operation on the encrypted database; converting the database instruction into a computing instruction to be executed by the second computing unit, and transmitting the computing instruction to the second computing unit; performing, by the second computing unit according to the computing instruction, a cryptographic operation corresponding to the target operation on ciphertext data in the encrypted database and the ciphertext parameter, to obtain a ciphertext result; and transmitting, by the second computing unit, the ciphertext result to the first computing unit.
