Chorus: Scalable In-Band Trust Establishment for Multiple Constrained Devices Over the Insecure Wireless Channel

Secure initial trust establishment for multiple resource constrained devices is a fundamental issue underlying wireless networks. A number of protocols have been proposed for secure key deployment among nodes without prior shared secrets (ad hoc), however so far most of them rely on secure Out-Of-Band (OOB) channels (e.g., audio, visual) which either only work with a small number of devices or require auxiliary hardware. In this paper, for the first time, the authors design a solution that enables secure initialization of a group of wireless devices, which works merely within the wireless band.
