Key Exchange at the Physical Layer

Sobreira de Almeida, Antonio Pedro

Abstract:
Establishing a secret communication between two parties requires both legal parties to share a private key. One problem consists of finding a way to establish a shared secret key without the availability of a secure channel. One method uses the reciprocity and multipath interference properties of the wireless channel for this purpose. We analyze this technique in the following three aspects: vulnerabilities and attacks, improvements to the protocol and experimental validation.
