text: "We propose a new authentication protocol that is provably secure based on
a ring variant of the learning parity with noise (LPN) problem. The protocol follows
the design principle of the LPN-based protocol from Eurocrypt’11 (Kiltz et al.),
and like it, is a two round protocol secure against active attacks. Moreover,
our protocol has small communication complexity and a very small footprint which
makes it applicable in scenarios that involve low-cost, resource-constrained devices.\r\n\r\nPerformance-wise,
our protocol is more efficient than previous LPN-based schemes, such as the many
variants of the Hopper-Blum (HB) protocol and the aforementioned protocol from
Eurocrypt’11. Our implementation results show that it is even comparable to the
standard challenge-and-response protocols based on the AES block-cipher. Our basic
protocol is roughly 20 times slower than AES, but with the advantage of having
10 times smaller code size. Furthermore, if a few hundred bytes of non-volatile
memory are available to allow the storage of some off-line pre-computations, then
the online phase of our protocols is only twice as slow as AES.\r\n"

(259668- PSPC)\r\nWe would like to thank the anonymous referees of this confer-
ence and those of the ECRYPT Workshop on Lightweight Cryptography for very useful
comments, and in particular for the suggestion that the scheme is somewhat vulnerable
to a man-in-the-middle attack whenever an adversary observes two reader challenges
that are the same. We hope that the attack we described in Appendix A corresponds
to what the reviewer had in mind. We also thank Tanja Lange for pointing us to the
pa- per of [Kir11] and for discussions of some of her recent work. "
