Abstract:
A garbled circuit is generated for a client in a leakage-resilient manner with a reduced memory requirement. The garbled circuit is used for secure function evaluation between the client and a server. The garbled circuit is generated with a reduced storage requirement by obtaining a token from the server; querying the token gate-by-gate, wherein for each gate of the garbled circuit, the token generates new wire garblings and stores them with the client using a Stream Cipher and interacts with the leakage-protected area to generate a garbled table for the gate; and receiving the garbled circuit from the token. The token comprises a leakage-protected area. The Stream Cipher is leakage-resilient and can be a symmetric-key cryptographic primitive that has a secret key as an input and generates an unbounded stream of pseudorandom bits as an output. The number of evaluations of the Stream Cipher is kept to a substantial minimum.
