随机协议签署合同，认证邮件，抛硬币。该协议采用公理化定义的二选一不经意传输子协议，允许一方从两个可识别秘密中只传输一个秘密给对方。第一（第二）秘密以一半的概率被接收，而发送者不知道接收到的是哪一个秘密，提出了一种使用任意公钥密码体制的二选一不经意传输的实现方案。
Randomized protocols for signing contracts, certified mail, and flipping a coin are presented. The protocols use a 1-out-of-2 oblivious transfer subprotocol which is axiomatically defined.The 1-out-of-2 oblivious transfer allows one party to transfer exactly one secret, out of two recognizable secrets, to his counterpart. The first (second) secret is received with probability one half, while the sender is ignorant of which secret has been received.An implementation of the 1-out-of-2 oblivious transfer, using any public key cryptosystem, is presented.
