We demonstrate physical implementation of information-theoretic secure oblivious transfer based on bounded observability using optical correlated randomness in semiconductor lasers driven by common random light broadcast over optical fibers. We demonstrate that the scheme can achieve one-out-of-two oblivious transfer with effective key generation rate of 110 kb/s. The results show that this scheme is a promising approach to achieve information-theoretic secure oblivious transfer over long distances for future applications of secure computation such as privacy-preserving database mining, auctions and electronic-voting.
我们演示了基于半导体激光器中光纤传输的公共随机光驱动下的有限观测的光学关联随机性，实现了基于信息论的保密 oblivious 传输。我们证明了该方案可以以 110kb/s 的有效密钥生成率实现二选一 oblivious 传输。结果表明，该方案为未来保密计算的应用，如隐私保护数据库挖掘、拍卖和电子投票等，提供了一种在长距离上实现信息论安全 oblivious 传输的有前途的方法。
