An Active Attack Against HB+ - A Provably Secure Lightweight Authentication Protocol

Henri Gilbert, Matt Robshaw, and Herve Sibert

Abstract

Much research has focused on providing RFID tags with lightweight cryptographic functionality. The HB+ authentication protocol was recently proposed and claimed to be secure against both passive and active attacks. In this note we propose a linear-time active attack against HB+.
