hHB: a Harder HB+ Protocol
Ka Ahmad Khoureich
Abstract: In 2005, Juels and Weis proposed HB+, a perfectly adapted authentication protocol for resource-constrained devices such as RFID tags. The HB+ protocol is based on the Learning Parity with Noise (LPN) problem and is proven secure against active adversaries. Since a man-in-the-middle attack on HB+ due to Gilbert et al. was published, many proposals have been made to improve the HB+ protocol. But none of these was formally proven secure against general man-in-the-middle adversaries.
In this paper we present a solution to make the HB+ protocol resistant to general man-in-the-middle adversaries without exceeding the computational and storage capabilities of the RFID tag.
Category / Keywords: cryptographic protocols / RFID, Authentication, LPN, HB+, Man-In-the-Middle.
