摘要:

我们目前的实验数据在自由空间光(FSO)链路在人眼安全波长的消息传输,使用一个发送器和两个接收器终端,其中后两个是一个合法的接收器和窃听器组成的测试床。该测试平台允许我们模拟物理层(PHY)安全的典型场景,如卫星到地面激光通信。我们估计信息理论的指标,包括保密率,保密中断概率,并预期的代码长度为给定的保密标准的基础上观察到的信道统计。然后,我们讨论了在实际衰落条件下的安全消息传输的操作原理,并提供了一个多层的安全体系结构相结合的物理层安全和上层(算法)安全的指导方针。

英文摘要:

We present experimental data on message transmission in a free-space optical (FSO) link at an eye-safe wavelength, using a testbed consisting of one sender and two receiver terminals, where the latter two are a legitimate receiver and an eavesdropper. The testbed allows us to emulate a typical scenario of physical-layer (PHY) security such as satellite-to-ground laser communications. We estimate information-theoretic metrics including secrecy rate, secrecy outage probability, and expected code lengths for given secrecy criteria based on observed channel statistics. We then discuss operation principles of secure message transmission under realistic fading conditions, and provide a guideline on a multi-layer security architecture by combining PHY security and upper-layer (algorithmic) security.
