garbled circuit造句

• In more detail, the garbled circuit is computed as follows.
• For example, he may send an incorrect garbled circuit that computes a function revealing the receiver's input.
• More recently, there has been a focus on highly parallel implementations based on garbled circuits, designed to be run on CPUs with many cores.
• The public key ( PK ) is composed of all the ciphertexts that represent the garbled circuit, and the secret key ( SK ) is composed of all the random wire labels.
• At a high level, the sender prepares the garbled circuit and sends it to the receiver, who obliviously evaluates the circuit, learning the encodings corresponding to both his and the senders output.
• By construction it is easy to show security for the sender, as all the receiver can do is to evaluate a garbled circuit that would fail to reach the circuit-output wires if he deviated from the instructions.
• To accomplish this they developed a custom, better optimized circuit compiler than Fairplay and several new optimizations such as pipelining, whereby transmission of the garbled circuit across the network begins while the rest of the circuit is still being generated.
• This algorithm first generates a new pair of public and secret keys for the homomorphic encryption scheme, and then uses these keys with the homomorphic scheme to encrypt the correct input wires, represented as the secret key of the garbled circuit.
