Short-range wireless communication technologies have been used in many security-sensitive Smartphone applications and services such as contactless micro payment and device pairing. Typically, the data confidentiality of the existing short-range communication systems relies on so-called \"Key-exchange then encryption\" mechanism. Namely, both parties need to spend extra communication to establish a common key before transmitting their actual messages, which is inefficient, especially for short communication sessions. In this paper, the authors present PriWhisper - a keyless secure acoustic short-range communication system for Smartphones.
