Time for Change: How Clocks Break UWB Secure Ranging. (arXiv:2305.09433v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Due to its suitability for wireless ranging, Ultra-Wide Band (UWB) has gained
traction over the past years. UWB chips have been integrated into consumer
electronics and considered for security-relevant use cases, such as access
control or contactless payments. However, several publications in the recent
past have shown that it is difficult to protect the integrity of instance
measurements on the physical layer. In this paper, we identify transceiver
clock imperfections as a new, important parameter that has been widely ignored …
