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","lang":"eng"}],"alternative_title":["LNCS"],"acknowledgement":"Supported by the European Research Council / ERC Starting Grant (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.
