Cyclotomic rings
WebAbstract. A handful of recent cryptographic proposals rely on the conjectured hardness of the following problem in the ring of integers of a cyclotomic number field: given a basis of a principal ideal that is guaranteed to have a “rather short” generator, find such a generator. Recently, Bernstein and Campbell-Groves-Shepherd sketched ... WebThe concept of (s, t)-subtractive sets bridges group-based threshold cryptography to lattice settings, which is demonstrated by relating it to distributed pseudorandom functions. We study when (dual) Vandermonde systems of the form V T · z = s · w admit a solution z over a ring R, where VT is the Vandermonde matrix defined by a set T and where the “slack” …

WebIn this paper, based on the theory of inverse Gray mapping, two classes of new generalized cyclotomic quaternary sequences with period pq are constructed, where pq is a product of two large distinct primes. In addition, we give the linear complexity over the residue class ring Z4 via the Hamming weights of their Fourier spectral sequence.
