Authenticated key establishment is a central requirement for securing IoT devices. For efficiency and management reasons, it might be desirable to avoid public-key-based solutions that are ubiquitous in traditional Internet settings but have many drawbacks for resource-constrained (RC) nodes. We introduce a novel Vicinity-based Pairing (VP) mechanism that allows authenticating arbitrary ‘unloaded’...
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...
The need for secured communication between computationally weak wireless devices has driven the development of novel key generation protocols. Various schemes for extracting symmetric cryptographic keys out of wireless channel properties have been proposed during recent years, making the generation protocol more and more efficient for individual applications. However, often these schemes were evaluated...
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...
