Smart Card Based Security in Locator/Identifier-Split Architectures

Security is an essential business requirement towards communication networks and will play a major role in future internet concepts. Many researchers see security functionality as an integral part of a new architecture, which should be thought of as soon as the conceptional phase of any proposal. In this paper we discuss suggested security mechanisms for the so called Locator/Identifier-Split and outline problematic issues found in those concepts. Based on these observations, we propose a security architecture using smart cards, which allows for lifelong assigned identifiers and is able to handle key replacement and revocation. Furthermore, we discuss the aspect of initial bootstrap and how to integrate devices with very low computational power like sensors.
