The problem of measuring the distance between two electronic devices in the presence of an adversary is still open. Existing approaches based on distance-bounding protocols are subject to enlargement attacks that cause the target to be perceived farther than it actually is. Enlargement attacks represent a new challenge for the research field of secure localization. The contribution of this paper is twofold. First, we propose SecDEv, a secure distance-bounding protocol for wireless channels that withstands enlargement attacks based on jam-and-replay. By leveraging on the characteristics of radio frequency signals, SecDEv establishes a security horizon within which a distance is correctly measured and a jam-and-replay attack is detected. Second, we show how SecDEv improves the scalability of secure positioning techniques.

Abstract
The problem of measuring the distance between two electronic devices in the presence of an adversary is still open. Existing approaches based on distance-bounding protocols are subject to enlargement attacks that cause the target to be perceived farther than it actually is. Enlargement attacks represent a new challenge for the research field of secure localization. The contribution of this paper is twofold. First, we propose SecDEv, a secure distance-bounding protocol for wireless channels that withstands enlargement attacks based on jam-and-replay. By leveraging on the characteristics of radio frequency signals, SecDEv establishes a security horizon within which a distance is correctly measured and a jam-and-replay attack is detected. Second, we show how SecDEv improves the scalability of secure positioning techniques.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
