- Abstract
- A new method for developing post-quantum digital signature schemes on commutative algebras, multiplicative group of which has multidimensional cyclicity, is proposed. The method is based on the technique of doubling the verification equation. Novelty is the combination of vector and scalar multiplication when generating a public key. A computationally difficult problem used in the proposed method is assigned to the type of a hidden discrete logarithm problem.
