我们研究了高斯信道和平坦衰落信道下的信息理论安全密钥协商的信号集。Alice通过一个噪声信道向Bob发送信号，而Eve通过一个独立的噪声信道接收信号。通过利用这个噪声资源，Alice和Bob希望共享一个密钥，而Eve在这个密钥上的信息量可以忽略不计。我们提出了一个协议，允许爱丽丝和鲍勃共享一个共同的秘密信息，并包含一个有效的协议在信息理论意义上的信号集。
We study the signal sets for information theoretically secure key agreement with public discussion over the Gaussian and flat fading channels. Alice transmits signals to Bob over a noisy channel while Eve receives signals through an independent noisy channel. By utilizing this noisy resource, Alice and Bob wish to share a secret key on which Eve has a negligible amount of information. We present a protocol that allows Alice and Bob to share a common secret information, and encompass the signal sets for an efficient protocol in information theoretic sense.
