Short paper: gathering tamper evidence in wi-fi networks based on channel state information |
Abstract | ||
|---|---|---|
Wireless devices are often used in application scenarios with strict security requirements. Examples are physical intrusion detection systems commonly used to protect factories, airports or government buildings. In such scenarios, additional security features such as tamper detection are highly desirable to complement traditional cryptographic mechanisms. In this paper we use channel state information (CSI), extracted from off-the-shelf 802.11n Wi-Fi cards, to calculate a tamper-evidence value for transmitters. This value enables detection of tampering due to device movement or replacement. We describe algorithms for tamper-evidence value computation, discuss the interpretation of this value and evaluate its effectiveness. |
