Abstract
A homomorphic encryption system evaluates homomorphically encrypted data, including receiving ciphertext input homomorphically encrypted from a plaintext input using a set-system including sets having an intersection property. An arithmetic function is evaluated on the ciphertext input to generate a ciphertext output, the arithmetic function including one or more additive gates and one or more multiplicative gates, wherein the evaluating operation generates errors during evaluation of the arithmetic function and the intersection property of the sets cancel out the errors during the evaluating operation. The ciphertext output is transmitted for homomorphic decryption to generate a plaintext result.
