HB-MP Protocol: An Improvement on the HB-MP Protocol
نویسندگان
چکیده
In this paper, we propose an enhanced version of the HB-MP authentication protocol, called the HB-MP protocol. The HB-MP protocol is a lightweight authentication protocol that is suitable for use in passive radio frequency identification (RFID) systems. The HB-MP protocol overcomes the man-in-the-middle attack to which the basic HB-MP protocol is vulnerable while maintaining its suitability to low-cost passive RFID systems. We show an effective man-in-the-middle attack against the HB-MP protocol where the attacker utilizes the predictable rotation of the secret key. We enhance the HB-MP protocol by randomizing the rotation of the secret key, which eliminates the vulnerability. We also propose the use of round keys that may be produced by rotation or, more generally, by a one-way function. We analyse the security and performance improvements of our HB-MP protocol and find it to be suitable for passive RFID systems.

Lightweight RFID Authentication Protocols for Special Schemes
This thesis addresses the problem of providing secure protocols for the practical application of low cost Radio-Frequency Identification (RFID) tags. This is particularly challenging because the tags are limited in cryptographic functionality and general performance, but also when there is a need to read multiple tags in a range of practical environments whilst maintaining data privacy. Several...
متن کاملSecure and Efficient HB-CM Entity Authentication Protocol
The simple, computationally efficient LPN-based HB-like entity authentication protocols have attracted a great deal of attention in the past few years due to the broad application prospect in low-cost pervasive devices. At present, the most efficient protocol is HB, which is proven to resist the GRS attack under the conjecture that it is secure in the DET-model. In this paper, we introduce an i...
متن کاملSecuring HB against GRS Man-in-the-Middle Attack
In Crypto’05, Juels and Weis proposed an efficient and provably secure authentication protocol for RFID devices, namely HB. The protocol is adapted from a human authentication protocol called HB which was proposed earlier by Hopper and Blum. Although HB is more secure than HB in order to be secure in a RFID environment, HB still suffers from an inherent weakness of HB. That is HB+ is not shown ...
متن کاملLinear HB ( NLHB ) Protocol Against Passive Attack
As a variant of the HB authentication protocol for RFID systems, which relies on the complexity of decoding linear codes against passive attacks, Madhavan et al. presented Non-Linear HB(NLHB) protocol. In contrast to HB, NLHB relies on the complexity of decoding a class of non-linear codes to render the passive attacks proposed against HB ineffective. Based on the fact that there has been no pa...
