Summary:
The man-in-the-middle attack is a real concern in mobile NFC (Near Filed Communication) payment and data sharing applications. Hence, it is necessary to exchange a secret key between devices without wireless communication. In this paper, we propose a non-interactive vibration-based key exchange between two smart devices on the desk. In our scheme, two devices are assumed to be placed next to each other. Each device then vibrates with patterns converted from a key to be exchanged and measures them with accelerometers. Finally, each key is recovered from measured acceleration. We implement our scheme with Android smartphones to show the effectiveness of the proposed scheme.
