论文摘要
在两个合法方之间利用渠道互惠的Secret-key生成是一个有趣的替代解决方案，用于无线系统中的密钥分布的加密原语，因为它不依赖访问基础架构并提供信息理论安全性。文献中绝大多数作品通常都假定窃听者没有从她的观察结果中获得有关钥匙的侧面信息，前提是（i）它的间隔不仅仅是远离合法政党的波长，并且（ii）该通道在散射中足够丰富。在本文中，我们表明这种情况并不总是在实践中得到验证，我们分析了在现实的传播条件下的秘密键能力。
Secret-key generation exploiting the channel reciprocity between two legitimate parties is an interesting alternative solution to cryptographic primitives for key distribution in wireless systems as it does not rely on an access infrastructure and provides information-theoretic security. The large majority of works in the literature generally assumes that the eavesdropper gets no side information about the key from her observations provided that (i) it is spaced more than a wavelength away from a legitimate party and (ii) the channel is rich enough in scattering. In this paper, we show that this condition is not always verified in practice and we analyze the secret-key capacity under realistic propagation conditions.
