Privacy-Preserving ECC-Based Grouping Proofs for RFID
نویسندگان
چکیده
The concept of grouping proofs has been introduced by Juels to permit RFID tags to generate a verifiable proof that they have been scanned simultaneously, even when readers or tags are potentially untrusted. In this paper, we extend this concept and propose a narrowstrong privacy-preserving RFID grouping proof and demonstrate that it can easily be extended to use cases with more than two tags, without any additional cost for an RFID tag. Our protocols rely exclusively on the use of Elliptic Curve Cryptography (ECC). To illustrate the implementation feasibility of our proposed solutions, we present a novel ECC hardware architecture designed for RFID.

A Privacy-Preserving Grouping Proof Protocol Based on ECC with Untraceability for RFID
An RFID (Radio-Frequency IDentification) system provides the mechanism to identify tags to readers and then to execute specific RFID-enabled applications. In those applications, secure protocols using lightweight cryptography need to be developed and the privacy of tags must be ensured. In 2010, Batina et al. proposed a privacy-preserving grouping proof protocol for RFID based on ECC (Elliptic ...
متن کاملAn Anonymous Offline RFID Grouping-Proof Protocol
As more and more items are tagged with RFID (Radio Frequency Identification) tags, grouping-proof technology is widely utilized to provide a coexistence evidence for a group of related items. Due to the wireless channel used in RFID systems, a security risk exists in the communication between the reader and tags. How to ensure the tag’s information security and to generate reliable grouping-pro...
متن کاملA Privacy-preserving RFID Authenticate Protocols against Man-in-the- middle Attacks
Radio Frequency Identification (RFID) is a technology designed to automatically identify a myriad of everyday objects and people. Due to widely spread of the RFID applications, some useful message can be attacked by adversaries. Thus, to eliminate the security problem, the security requirements for privacy-preserving RFID authentication protocols are evident. In this paper, we discuss unique ma...
متن کاملSecurity Analysis of a Privacy-preserving ECC-based Grouping-proof Protocol
Batina et al. have proposed a privacy-preserving grouping-proof RFID protocol with colluding tag prevention (CTP) recently which relies exclusively on the use of Elliptic Curve Cryptography (ECC). In this paper, we show that this proposed protocol is not secure against the tracking attack. To make this attack successfully, the adversary needs to execute three phases. Firstly, the attacker just ...
متن کاملWide Strong Private RFID Identification based on Zero-Knowledge
We present the first wide-forward-insider and wide-strong RFID identification protocols that are based on zero-knowledge. Until now these notions have only been achieved by schemes based on IND-CCA2 encryption. We discuss why wideforward-insider privacy is sufficient for most practical applications. Rigorous proofs in the standard model are provided for the security and privacy properties of ou...
