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 ... WebJun 5, 2024 · This comes as a direct application of our more general result that states that all non-zero polynomials with ``small'' coefficients in the cyclotomic ring Z p [ X] / ( Φ m ( X)) are invertible (where ``small'' depends on the size of p and how many irreducible factors the m t h cyclotomic polynomial Φ m ( X) splits into).
