Bootstrappable homomorphic encryption method, computer program and apparatus

摘要

Embodiments of the present invention describe a fully homomorphic encryption scheme using a "bootstrapable" homomorphic encryption scheme that evaluate a function f when f is the encryption schemes own decryption function. Specifically, the fully homomorphic encryption scheme uses the "bootstrapable" homomorphic encryption scheme to determine the decryption function to decrypt data encrypted under the fully homomorphic encryption scheme.
