Detecting Relay Attacks with Timing Based Protocols
Distance bounding protocols have been proposed as means of detecting relay attacks, also known as 'mafia fraud'. In this paper we present the first symmetric key based distance bounding protocol that is also resistant to so-called 'terrorist fraud', a variant of mafia fraud. Relay attacks present a serious threat to RF security devices (contactless smart cards, RFID tags and the like) because they undermine the implicit assumption that the device is physically close to the reader when it is operating. In applications such as physical access control this assumption of physical proximity is all-important. Distance bounding protocols require a communication channel that can exchange single bits with extremely low latency. This unconventional communication requirement has prompted Hancke and Kuhn to assert in a recent publication that ultra wide band (UWB) radio is necessary to achieve a useful distance bounding resolution. We analyse this assertion and present a alternative, novel communication approach that leverages the phenomena of side channel leakage to deliver a low latency channel. Our proposal is capable of detecting sophisticated relay attacks without resorting to the considerable expense and complexity of UWB radio. We present experimental results to support our arguments.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
