Secure & Lightweight Distance-Bounding
Distance-bounding is a practical solution aiming to prevent relay attacks. The main challenge when designing such protocols is maintaining their inexpensive cryptographic nature, whilst being able to protect against as many, if not all, of the classical threats posed in their context. Moreover, in distancebounding, some subtle security shortcomings related to the PRF (pseudorandom function) ass...
متن کاملTowards Secure Distance Bounding
Relay attacks (and, more generally, man-in-the-middle attacks) are a serious threat against many access control and payment schemes. In this work, we present distance-bounding protocols, how these can deter relay attacks, and the security models formalizing these protocols. We show several pitfalls making existing protocols insecure (or at least, vulnerable, in some cases). Then, we introduce t...
متن کاملDistance Lower Bounding
Distance (upper)-bounding (DUB) allows a verifier to know whether a proving party is located within a certain distance bound. DUB protocols have many applications in secure authentication and location based services. We consider the dual problem of distance lower bounding (DLB), where the prover proves it is outside a distance bound to the verifier. We motivate this problem through a number of ...
متن کاملDistance Bounding in Noisy Environments
Location information can be used to enhance mutual entity authentication protocols in wireless ad-hoc networks. More specifically, distance bounding protocols have been introduced by Brands and Chaum at Eurocrypt’93 to preclude distance fraud and mafia fraud attacks, in which a local impersonator exploits a remote honest user. Hancke and Kuhn have proposed a solution to cope with noisy channels...
متن کاملRFID Distance Bounding Protocols
Almost all existing RFID tag/reader authentication protocols are vulnerable to mafia attacks and/or terrorist attacks from adversaries because of their inability to verify location of the tag. Several protocols have been proposed that purport to alleviate these forms of attacks. However, vulnerabilities have been identified in most of these protocols. We present and evaluate a modified distance...
