Secure and Accurate Distance Bounding for Bluetooth Secure Access

Are you involved in the design and development of products that rely on secure proximity systems such as keyless entry, contactless payment or real-time location systems (RTLS)? Then security is without a doubt one of your major concerns. More specifically, the threat of relay attacks that allow criminals to decrease the measured proximity between two legitimate entities, giving them unauthorized access to vehicles, buildings or data.

This white paper describes a method to successfully deflect any such relay attack. It consists of a distance bounding protocol for Bluetooth Low Energy radios, and its feasibility and practicality are established by the implementation of the solution on an NXP KW36 Bluetooth Low Energy radio platform.
