Abstract
Provides is an adaptive homomorphic encryption method based on a trusted execution environment. The method can achieve adaptive configuration and switching of homomorphic encryption parameters and schemes in a chip-level security environment. While ensuring the security of private data and computing results, the efficiency of a homomorphic encryption algorithm is improved, and the usability of different homomorphic encryption algorithms is expanded, thus greatly improving the practicability of a homomorphic encryption method, and promoting the implementation of a privacy protection technology with innovative ideas of integrating different technical routes.
