Secure Proximity Detection and Verification: Addressing vulnerabilities in IEEE 802.15.4z UWB

We live in a world where much of our interactions with the environment around us depend on us being physically close to them. For instance, we have proximity­based tokens (e.g., keys and smartcards) for access systems installed at various places such as in cars, at contactless payment terminals, and in electronic passports. Moreover, such...

Improving Ultrawide Band Ranging Using Two Antennas

Ultrawideband technology can be used to measure the distance between two device equipped with ultrawideband transceivers. Multiple ultrawideband devices known as anchors can localize a device that supports ultrawideband communication after each anchor measures the distance between itself and the device. The anchor and the tag can measure the...
