为了克服量子密钥分发、后量子密码和基于计算安全的密码协议的局限性，提出了一种大气湍流控制密码体制。该加密方案采用传统方案，仅在初始化阶段利用大气湍流作为公共随机性来源来确定用于该加密方案的公共参数。为了克服传统方案的低密钥率，受湍流通道长相干时间T_c的制约，该加密方案每隔T_c秒更新伽马-伽马分布参数，用于生成用于基于累积分布函数确定密钥的辐照度样本，从而由大气湍流通道来整形最终密钥。我们还描述了一种方案，该方案随机选择几个可用路径中的一个，其中在交织之后使用同时测量的辐照度样本来生成原始密钥。与相应的传统QKD和信源类型物理层安全方案相比，所提出方案的密钥速率高出数量级，并且与最先进的光通信数据速率相当。
To overcome the limitations of QKD, post-quantum cryptography, and computational security-based cryptography protocols in this paper, an atmospheric turbulence-controlled cryptosystem is proposed. The proposed encryption scheme employs the traditional scheme to utilize the atmospheric turbulence as the common source of randomness only in the initialization stage to determine the common parameters to be used in the proposed encryption scheme. To overcome low secret-key rates of traditional scheme, dictated by the long coherence time Tc of turbulence channel, the proposed encryption scheme updates the parameters of gamma-gamma distribution, used to generate irradiance samples for cumulative distribution function-based determination of the key, every Tc seconds and as such the final key is shaped by the atmospheric turbulence channel. We also describe a scheme that randomly selects one of several available paths in which the simultaneously measured irradiance samples, after interleaving, are used to generate the raw key. The secret-key rates of the proposed schemes are orders of magnitude higher compared to corresponding traditional QKD and source type physical-layer security schemes and are comparable with the state-of-the-art optical communication data rates.
