Abstract
A method of outsourcing an operation with encryption is provided. A method may include encrypting data at trusted execution environment (TEE) to generate a first ciphertext. The method may also include conveying the first ciphertext to a graphics processing unit (GPU). Further, the method may include performing, at the GPU, at least one somewhat homomorphic encryption (SHE) evaluation operation on the first ciphertext to generate a second ciphertext. Moreover, the method may include conveying the second ciphertext to the TEE. In addition, the method may include decrypting, at the TEE, the second ciphertext to generate a function.
