Physical Layer Security (PHYSEC) has the potential to offer substantial advantages for key management for small resource-constrained devices. In this paper, we investigate two PHYSEC primitives: channel reciprocity based key generation (CRKG) and channel reciprocity based relay detection (CRRD). The security and entry performance of such systems in real-world scenarios are still open research questions...
Secret key establishment based on parameters of the communication channel is a highly attractive option for many applications that operate in a dynamic mobile environment with peer-to-peer association. On the other hand, high usability and dynamic key management are still very difficult to achieve for wireless devices which have to operate under strict resource constraints. In fact, most previously...
