Vehicular ad hoc networks (VANETs) are envisioned to support the development of a wide range of attractive applications such as payment services which require the design of payment systems that satisfy additional requirements associated with VANETs. The wide range of scenarios (with or without connectivity restriction) arising from vehicle-to-vehicle and(More)
In this paper we present an anonymous protocol for a mobile payment system based on a Kiosk Centric Case Mobile Scenario where the customer cannot communicate with the issuer due to absence of Internet access with her mobile device and the costs of implementing other mechanism of communication between both of them are high. Our protocol protects the real(More)
Recent advances in m-commerce have raised the usage of scenarios with communication restrictions. These scenarios create new security challenges which must be considered by protocol's designers in order to achieve the same security capabilities as in those protocols designed for mobile payment systems based on a 'Full connectivity' scenario (where all the(More)
This paper proposes a new authentication and authorization architecture based on a network smart card with identification purposes: ID-NSCard. Thus, a citizen who holds this kind of device might be securely authenticated by a remote authoritative server in an identification system. This work shows how the standardized specifications are transparently reused(More)
