Abstract
An ultra-wideband (UWB) system of a user device is disclosed. The UWB system receives a session identifier associated with a first session key from an access control device to facilitate an access control operation for the user device. Based on successful mutual authentication between the user device and the access control device, a secure data exchange session is scheduled between the user device and the access control device based on the first session key and a second session key that is generated by a secure element of the user device. First transaction payloads that include the session identifier are received from the access control device during the secure data exchange session. The first transaction payloads are decrypted by way of a ranging payload set, to generate second transaction payloads. The access control operation is executed based on the second transaction payloads.
