Wireless Device Key Generation Public
Downloadable Contentopen in viewer
Security is an important concern in today’s society. While securing communications is difficult to accomplish, securing wireless communications is the most difficult due to its broadcast nature and the randomness of wireless channels. Current physical layer security approaches argue that channel randomness can be exploited to ensure secure communications. The wireless channel between communicating users can be used to generate secret keys known only to them. It would be nearly impossible for a user eavesdropping on their communications to generate this same key due to inherent differences in channel properties. This approach for wireless key generation is discussed, implemented, and tested using various scenarios to prove that the communication over the wireless medium is secure.
