CLIMEX:一种基于时钟脉冲交换的无线物理层安全协议

CLIMEX: A Wireless Physical Layer Security Protocol Based on Clocked Impulse Exchanges

Satyam Dwivedi, John Olof Nilsson, Panos Papadimitratos, Peter Händel

摘要:

提出了一种新的基于物理参数的用户间公共秘密建立方法和协议。用户的四个物理参数是他们的时钟频率,他们的相对时钟相位和他们之间的距离。两个用户之间提出的协议是由理论模型的测量。此外,估计器被提出来估计秘密的物理参数。物理交换的参数被证明是安全的,凭借其不可观测性的对手。在一个简化的分析的基础上的测试台设置,它表明,38位的共同保密性,可以得出一个运行的建议协议之间的用户。该方法对各种主动定时攻击和主动冒充攻击具有较好的鲁棒性。

英文摘要:

A novel method and protocol establishing common secrecy based on physical parameters between two users is proposed. The four physical parameters of users are their clock frequencies, their relative clock phases and the distance between them. The protocol proposed between two users is backed by theoretical model for the measurements. Further, estimators are proposed to estimate secret physical parameters. Physically exchanged parameters are shown to be secure by virtue of their non-observability to adversaries. Under a simplified analysis based on a testbed settings, it is shown that 38 bits of common secrecy can be derived for one run of the proposed protocol among users. The method proposed is also robust against various kinds of active timing attacks and active impersonating adversaries.
