With the decreasing cost of smart cards, as well as their growing computational power and storage capacity, a new door has been opened to a whole new variety of security mechanisms, making them ideal candidates for authentication devices. The current generation of smart cards is both convenient and e cient. Their security properties, the multi-application smart card operating systems and the standardization of smart card are expanding the range of potential applications. Nevertheless, despite the constant technological improvements, smart cards remain resource-constrained devices. Therefore, providing advanced authentication schemes is not enough - the performance of the authentication schemes, protocols and key lengths must be useful in practice.
