Title: Secure device pairing based on a visual channel Authors: Nitesh Saxena; Jan-Erik Ekberg; Kari Kostiainen; N. Asokan Venue: Proceedings - IEEE Symposium on Security and Privacy/Proceedings of the ...

McCune et al., (2005) proposed that one device displays the hash of its public key in the form of a barcode, and the other device reads it using a camera. Mutual authentication requires switching the roles of the devices and repeating the above process in the reverse direction. In this paper, we show how strong mutual authentication can be achieved even with a unidirectional visual channel, without having to switch device roles. By adopting recently proposed improved pairing protocols, we propose how visual channel authentication can be used even on devices that have very limited displaying capabilities
