The Rayleigh quotient of a bent function is an invariant under the action of the orthogonal group, and it measures the distance of the function to its dual. An efficient algorithm ...

Let f : F n 2 → F n 2 be an almost perfect nonlinear function (APN). The set Df := {(a, b) : f(x + a) − f(x) = b has two solutions} can be used to distinguish APN functions up ...
This paper presents efficient formulas for computing cryptographic pairings on the curve y2 = cx3 + 1 over fields of large characteristic. We provide examples of pairing-friendly...
Abstract. In order to increase the security for authenticated key exchange protocols, various authentication means can be used together. In this paper, we introduce a security mode...
We propose GMSS, a new variant of the Merkle signature scheme. GMSS is the first Merkle-type signature scheme that allows a cryptographically unlimited (280 ) number of documents ...
