Secure distance measurement and therefore secure Time-of-Arrival (ToA)\nmeasurement is critical for applications such as contactless payments,\npassive-keyless entry and start systems, and navigation systems. This paper\ninitiates the study of Message Time of Arrival Codes (MTACs) and their\nsecurity. MTACs represent a core primitive in the construction of systems for\nsecure ToA measurement. By surfacing MTACs in this way, we are able for the\nfirst time to formally define the security requirements of physical-layer\nmeasures that protect ToA measurement systems against attacks. Our viewpoint\nalso enables us to provide a unified presentation of existing MTACs (such as\nthose proposed in distance-bounding protocols and in a secure distance\nmeasurement standard) and to propose basic principles for protecting ToA\nmeasurement systems against attacks that remain unaddressed by existing\nmechanisms. We also use our perspective to systematically explore the tradeoffs\nbetween security and performance that apply to all signal modulation techniques\nenabling ToA measurements.\n
