SECURE WIRELESS LOCALIZATION USING TRUSTED EXECUTION ENVIRONMENTS

Through wireless localization, the position of a device (user) can be computed in a world coordinate system using wireless signals. Wireless localization systems for estimating device/user location typically involve fusing measurement data obtained from multiple access points (APs) by compute end-point, such as a cloud/edge-node. Such systems, however, are prone to attacks that can be launched against a compute end-point. To address such issues, techniques herein involve running wireless localization algorithms on a new paradigm of computing involving secure enclave technology through which localization algorithms can be protected from tampering. As a result, applications that may be vulnerable to location manipulation can be more trusted to take action based on their own interpretations of sensor data
