Modulating a noisy carrier signal for eavesdropping-resistant HF RFID

SummaryEavesdropping RFID systems can violate privacy. We propose a privacy-friendly RFID system, in which the chip modulates its reply onto a noisy carrier provided by the reader, to protect the back-channel against eavesdropping. This method does not require additional protective devices and resolves some practical weaknesses of previous proposals.ZusammenfassungAbhörangriffe gegen RFID-Systeme können die Privatsphäre verletzen. Der Autor schlägt ein datenschutzfreundliches RFID-System vor, in dem der Chip seine Antwort auf das verrauschte Trägersignal des Lesegerätes moduliert, um den Antwortkanal gegen Abhören zu sichern. Diese Technik benötigt keine zusätzlichen Schutzgeräte und vermeidet einige praktische Probleme vorangegangener Ansätze.
