Secure communication for RFIDs proactive information security within computational security

Abstract

We consider repeated communication sessions between a sender (e.g., Radio Frequency Identification, RFID, reader) and a receiver (RFID). A proactive information security scheme is proposed. The scheme is based on the assumption that the information exchanged during at least one of every n successive communication sessions is not exposed to an adversary. Then a computational secure scheme based on the information secure scheme is used to ensure that even in the case that the adversary listens to all the information exchanges, the communication between the sender and the receiver is secure. In particular, the scheme can be used in the domain of remote controls (e.g., for cars). © Springer-Verlag Berlin Heidelberg 2006.
