Solutions for an easy and secure setup of a wireless connection between two devices are urgently needed for WLAN, Wireless USB, Bluetooth and similar standards for short range wireless communication. All such key exchange protocols employ data authentication as an unavoidable subtask. As a solution, we propose an asymptotically optimal protocol family for data authentication that uses short manually authenticated out-of-band messages. Compared to previous articles by Vaudenay and Pasini the results of this paper are more general and based on weaker security assumptions. In addition to providing security proofs for our protocols, we focus also on implementation details and propose practically secure and efficient sub-primitives for applications.
