Instant and Robust Authentication and Key Agreement among Mobile DevicesAuthentication and Key Agreement • August 29th, 2016
Device-to-device communication is important to emerging mobile applications such as Internet of Things and mobile social networks. Authentication and key agreement among multiple legitimate devices is the important first step to build a secure communication channel. Existing solutions put the devices into physical proximity and use the common radio environment as a proof of identities and the common secret to agree on a same key. However they experience very slow secret bit generation rate and high errors, requiring sev- eral minutes to build a 256-bit key. In this work, we design and implement an authentication and key agreement proto- col for mobile devices, called The Dancing Signals (TDS), being extremely fast and error-free. TDS uses channel state information (CSI) as the common secret among legitimate devices. It guarantees that only devices in a close physical proximity can agree on a key and any device outside a cer- tain distance gets nothing about the key. Compared with existi
