Little is known about the true minimum distance of this family of negacyclic BCH codes and the dimension of this family of negacyclic BCH codes with large designed distance. The main objective of this paper is to study three subfamilies of this family of negacyclic BCH codes.

The minimum distances of the duals of the <i>q</i>-ary narrow-sense negacyclic BCH codes of length <i>n</i> are also investigated.

In this paper, we propose fault attacks on multi-prime RSA signatures under the PKCS#1 v2.x protocols. We conduct the fault attacks based on Coppersmith’s method in various scenarios. To be specific, we first consider the case where there is only one fault signature, and then we consider the cases where there are multiple fault signatures with co-prime moduli, common moduli, and arbitrary moduli. For each case, we give the upper bound of the unknowns that can be solved in polynomial time, which improves the practicability of the attacks.

This generalization corresponds to the fact that a vectorial function <span>(F:mathbb {F}_2^nmapsto mathbb {F}_2^m)</span> sums to a nonzero value over every <i>k</i>-dimensional affine subspace of <span>(mathbb {F}_2^n)</span>, for some <span>(kle n)</span> (APNness corresponds to <span>(k=2)</span>).

We study in the present paper the case of vector (i.e. linear) subspaces, which is much less simple to handle. The sum depends on a coefficient in subspace polynomials. We study for which values of <i>k</i> the multiplicative inverse function can sum to nonzero values over all <i>k</i>-dimensional vector subspaces.

We study the behavior of the inverse function over direct sums of vector spaces and we deduce that the property of the inverse function to be <i>k</i>th-order sum-free happens for <i>k</i> if and only if it happens for <span>(n-k)</span>. We derive several other results and we show that the set of values <i>k</i> such that the inverse function is not <i>k</i>th-order sum-free is stable when adding two values of <i>k</i> whose product is smaller than <i>n</i> (and when subtracting two values under some conditions).
