Private and Secure Public-Key Distance Bounding: Application to NFC Payment

Distance-Bounding is used to defeat relay attacks. For wireless payment systems, the payment terminal is not always online. So, the protocol must rely on a public key for the prover (payer). We propose a generic transformation of a (weakly secure) symmetric distance bounding protocol which has no post-verification into wide-strong-private and secure public-key distance bounding.
