Cryptographic Approach to “Privacy-Friendly” Tags
TLDR
This paper discusses and clarifies the requirements and restrictions of RFID systems, and suggests the use of the previously proposed scheme, which protects user privacy using a low-cost hash chain mechanism.Abstract:
Radio frequency identification (RFID) is expected to become an important and ubiquitous infrastructure technology. As RFID tags are affixed to everyday items, they may be used to support various useful services. However, widespread deployment of RFID tags may create new threats to user privacy, due to the powerful tracking capability of the tags. There are several important technical points when constructing an RFID scheme. Particularly important is ensuring forward security, i.e., data transmitted today will still be secure even if secret tag information is revealed by tampering in the future. Low cost implementation is another key RFID requirement. This paper discusses and clarifies the requirements and restrictions of RFID systems. This paper also examines the features and issues pertinent to several existing RFID schemes. Finally, this paper suggests the use of our previously proposed scheme, which protects user privacy using a low-cost hash chain mechanism.read more

On privacy models for RFID
TL;DR: This model captures the notion of a powerful adversary who can monitor all communications, trace tags within a limited period of time, corrupt tags, and get side channel information on the reader output.

The blocker tag: selective blocking of RFID tags for consumer privacy
TL;DR: This work proposes the use of "selective blocking" by "blocker tags" as a way of protecting consumers from unwanted scanning of RFID tags attached to items they may be carrying or wearing, and believes that this approach provides a very attractive alternative for addressing privacy concerns raised by the potential (and likely) widespread use ofRFID tags in consumer products.

Minimalist cryptography for low-cost RFID tags (extended abstract)
TL;DR: It is shown that standard cryptography is not necessary as a starting point for improving security of very weak RFID devices, and a new security model for authentication and privacy in RFID tags is proposed, which involves no computationally intensive cryptographic operations, and relatively little storage.
