Abstract

In this paper we present a new privacy scheme against passive adversaries based on the message modulation instead of classical cryptographic models for low cost wireless devices, such as an RFID tag. The idea is to become the adversary in disadvantage related to the reader-tag communication channel, for example, by reducing her signal-to-noise ratio.
