论文摘要
中继攻击在无线范围和身份验证系统中构成了重要威胁。已经提出了距离界限协议作为对这些攻击的有效对策,并允许验证者和供摊子在它们之间的距离上建立上限。但是,由于严格的实施要求,在实践中很难实现安全距离边界协议。在本文中,我们研究了一个尚未开发的研究领域,并通过在接收器的解码和解码过程中施加几个其他安全约束,从而显示了超宽频段(UWB)距离边界协议的安全强度如何显着提高。我们证明,对于与最先进的UWB距离边界协议一样,我们的解决方案将继电器攻击的成功概率降低了40倍。此外,我们还认为,我们的安全解决方案仅需要将我们的安全解决方案与脉冲掩模相结合,并且可以与距离掩盖合并,并且可以实现这些安全界限,并且无需实现这些模型的脉动重新计算。
Relay attacks pose an important threat in wireless ranging and authentication systems. Distance bounding protocols have been proposed as an effective countermeasure against these attacks and allow a verifier and a prover to establish an upper bound on the distance between them. However, secure distance bounding protocols are hard to realize in practice due to stringent implementation requirements. In this paper, we look into a yet unexplored research area and show how the security strength of Ultra Wide Band (UWB) distance bounding protocols can be significantly increased by imposing several additional security constraints during demodulation and decoding at the receiver. We demonstrate that for equal reliability metrics as in state-of-the-art UWB distance bounding protocols, our solution achieves a reduction of the success probability of a relay attack by a factor of 40. Moreover, we also argue that our security solution only needs to be combined with pulse masking and a distance commitment to achieve these security bounds and there is no need to have pulse reordering in our modulation.
