Title:
Efficient Garbling from a Fixed-Key Blockcipher
Authors: Mihir Bellare, Viet Tung Hoang, Sriram Keelveedhi, Phillip Rogaway
Abstract:We advocate schemes based on fixed-key AES as the best route to highly efficient circuit-garbling. We provide such schemes making only one AES call per garbled-gate evaluation. On the theoretical side, we justify the security of these methods in the random-permutation model, where parties have access to a public random permutation. On the practical side, we provide the JustGarble system, which implements our schemes. JustGarble evaluates moderate-sized garbled-circuits at an amortized cost of 23.2 cycles per gate (7.25 nsec), far faster than any prior reported results.
