Minimalist Cryptography for Low-Cost RFID Tags
A radio-frequency identification (RFID) tag is a small, inexpensive microchip that emits an identifier in response to a query from a nearby reader. The price of these tags promises to drop to the range of $0.05 per unit in the next several years, offering a viable and powerful replacement for barcodes. The challenge in providing security for low-cost RFID tags is that they are computationally w...
متن کاملPractical Schemes For Privacy & Security Enhanced RFID
Proper privacy protection in RFID systems is important. However, many of the schemes known are impractical. Some use hash functions instead of the more hardware efficient symmetric encryption schemes as a cryptographic primitive. Others incur a rather large time penalty at the reader side, because the reader has to perform a key search over large tag key space. Moreover, they do not allow for d...
متن کاملRFID Privacy Based on Public-Key Cryptography
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 whic...
متن کاملLow-Cost Cryptography for Privacy in RFID Systems
Massively deploying RFID systems while preserving people's privacy and data integrity is a major security challenge of the coming years. Up to now, it was commonly believed that, due to the very limited computational resources of RFID tags, only ad hoc methods could be used to address this problem. Unfortunately, not only those methods generally provide a weak level of security and practicality...
متن کاملPractical Schemes For Privacy & Security Enhanced RFID ( extended abstract )
Proper privacy protection in RFID systems is important. However, many of the schemes known are impractical, either because they use hash functions instead of the more hardware efficient symmetric encryption schemes as a efficient cryptographic primitive, or because they incur a rather costly key search time penalty at the reader. Moreover, they do not allow for dynamic, fine-grained access cont...
