摘要：
In one embodiment, data for use by a processor is stored in a memory. A network interface communicates over a network with a second device. At a processor, a Somewhat Homomorphic Encryption (SHE) of a plurality of secret shares is generated. The SHE of the plurality of secret shares is sent to the second device. The following is performed in a loop: a first result of a homomorphic exclusive-or operation performed by the second device on the SHE is received, a SHE of the first result is performed, yielding a second result, a SHE of the second result is performed yielding a third result, the third result is transmitted to the second device, and a final SHE result is received from the second device. The received final SHE result is decrypted in order to produce a final Somewhat Homomorphically Decrypted (SHD) output. The final SHD output is then output. Related methods, systems, and apparatus are also described.
