Abstract
A communication device is provided, comprising: an ultra-wideband device configured to establish a communication session with an external communication device; a secure element configured to generate a session key for use in said communication session and an authentication key derived from said session key; a processing unit configured to execute an application; wherein the secure element is further configured to transfer the session key and the authentication key to the UWB device; wherein the UWB device is configured to add, upon or after receiving data for use by said application, a cryptographic tag to said data; wherein the processing unit is configured to receive said data and the cryptographic tag, and to forward said data and cryptographic tag to the secure element; wherein the secure element is configured to verify said cryptographic tag and to return, upon or after a positive verification of the cryptographic tag, a signed confirmation.
