Shake Well Before Use: Authentication Based on Accelerometer Data

摘要: Small, mobile devices without user interfaces, such as Bluetooth headsets, often need to communicate securely over wireless networks. Active attacks can only be prevented by authenticating communication, which is problematic when do not have any a priori information about each other. We introduce new method for device-to-device authentication shaking together. This paper describes two protocols combining cryptographic techniques with known methods of accelerometer data analysis the effect generating authenticated, secret keys. The differ in their design, one being more conservative from security point view, while other allows dynamic interactions. Three experiments are used optimize and validate our proposed method.
