Abstract

The design of ultralightweight authentication protocols that conform to low-cost tag requirements is imperative. This paper analyses the most important proposals (except for those based in hard problems such as the HB [1-3] family) in the area [4-6] and identifies the common weaknesses that have left all of them open to various attacks [7-11]. Finally, we present Gossamer, a new protocol inspired by the recently published SASI scheme [13], that was lately also the subject of a disclosure attack by Hernandez-Castro et al.[14]. Specifically, this new protocol is designed to avoid the problems of the past, and we examine in some deep its security and performance.
