Abstract
Provided is a confidential computing-based method for customizedly balancing between security and performance of homomorphic encryption, including the following steps: receiving a computing task, security and performance custom parameters, and encrypted computing data; when a user performs security customization, dividing the computing data into multiple security levels according to the security custom parameters, and according to the security levels of data involved in computing, executing partial corresponding computing task outside a trusted execution environment, and executing partial computing task in the trusted execution environment; when the user performs performance customization, dynamically allocating resources according to the performance custom parameters, executing partial computing task in the trusted execution environment, and executing partial computing task outside the trusted execution environment; and finally, returning a computing result to a request side.
