EC-RAC (ECDLP Based Randomized Access Control): Provably Secure RFID authentication protocol

Y. Lee, L. Batina, I. Verbauwhede
Computer Science
IEEE International Conference on RFID
16 April 2008

We design a new authentication protocol named EC-RAC using EC (Elliptic Curve) cryptography to satisfy the requirements of RFID systems. Expand

Elliptic-Curve-Based Security Processor for RFID

Y. Lee, K. Sakiyama, L. Batina, I. Verbauwhede
Computer Science
IEEE Transactions on Computers
1 November 2008

We present an architecture of a state-of-the-art processor for RFID tags with an elliptic curve (EC) processor over GF(2163). Expand

Untraceable RFID authentication protocols: Revision of EC-RAC

Y. Lee, L. Batina, Ingrid M. R. Verbauwhede
Computer Science
IEEE International Conference on RFID
27 April 2009

In this paper we propose several authentication protocols that are all made of the same building blocks. Expand

Secure and Low-cost RFID Authentication Protocols

Y. Lee, I. Verbauwhede
Computer Science
2005

In this paper we propose two RFID (Radio Frequency Identification) authentication protocols for secure and lowcost RFID systems that require good operational and security properties. Expand

Low-cost untraceable authentication protocols for RFID

Y. Lee, L. Batina, Dave Singelée, I. Verbauwhede
Computer Science
WiSec '10
22 March 2010

We repair three revised EC-RAC protocols of Lee, Batina and Verbauwhede and show that two of the improved authentication protocols are wide-strong privacy-preserving and one wide-weak privacy-Preserving; we present the search protocol, a novel scheme which allows for privately querying a particular tag, and proof its security properties.

Privacy-Preserving ECC-Based Grouping Proofs for RFID

L. Batina, Y. Lee, S. Seys, Dave Singelée, I. Verbauwhede
Computer Science
ISC
25 October 2010

We propose a privacy-preserving RFID grouping proof and demonstrate that it can easily be extended to use cases with more than two tags. Expand

Extending ECC-based RFID authentication protocols to privacy-preserving multi-party grouping proofs

L. Batina, Y. Lee, S. Seys, Dave Singelée, I. Verbauwhede
Computer Science
Personal and Ubiquitous Computing
1 March 2012

We extend the notion of public-key RFID authentication protocols and propose a privacy-preserving multi-party grouping-proof protocol which relies exclusively on the use of elliptic curve cryptography (ECC). Expand

Privacy Challenges in RFID Systems

Y. Lee, L. Batina, I. Verbauwhede, I. Verbauwhede

We give an overview of security solutions for RFID systems and discuss their security properties. Expand

Online Video Recommendation through Tag-Cloud Aggregation

Jonghun Park, S. Lee, S. Lee, Kwanho Kim, Beom-Suk Chung, Y. Lee
Computer Science
IEEE MultiMedia
2011

A framework for recommending online videos operates by constructing user profiles as an aggregate of tag clouds and generating recommendations according to similar viewing patterns. Expand

Iteration Bound Analysis and Throughput Optimum Architecture of SHA-256 (384, 512) for Hardware Implementations

Y. Lee, H. Chan, I. Verbauwhede
Computer Science
WISA
27 August 2007

The hash algorithm forms the basis of many popular cryptographic protocols and it is therefore important to find throughput optimal implementations. Expand
