Abstract
IEEE 802.15.4z, a standard for Ultra-Wide Band (UWB) secure distance measurement, was adopted in 2020 and the chips that implement this standard are already deployed in mobile phones and in the automotive industry (for Passive Keyless Entry and Start). The standard specifies two different modes---LRP and HRP. Whereas the security of LRP mode has been analyzed, there is no publicly available security analysis of the HRP mode, which is used in different chips like NXP Trimension SR150/SR040, Samsung smartphones, and U1 chip deployed in Apple iPhones.
