RFID Privacy Based on Public-Key Cryptography (Abstract)
暂无分享,去创建一个
RFID systems makes it possible for a server to identify known tags in wireless settings. As they become more and more pervasive, people privacy is more and more threatened. In this talk, we list a few models for privacy in RFID and compare them. We review a few protocols. We further show that strong privacy mandates the use of public-key cryptography. Finally, we present a new cryptosystem which is dedicated to tiny hardware and which can be used to design secure RFID systems achieving strong privacy. Note: this paper contains new definitions and results that are announced in this talk. Details and proofs will appear in future papers. Credits: the work on RFID was done together with Salvatore Bocchetti as a part of his Master Thesis (3). We received many suggestions from Gildas Avoine. The work on the new cryptosystem was done together with Matthieu Finiasz (4) and was extended to- gether with Jean-Philippe Aumasson, and Willi Meier. Part of it was done in the Master Thesis of Jean-Philippe Aumasson (2).
