- Abstract
- This article examines aspects of constructing post-quantum algebraic digital signature algorithms based on the difficulty of solving large systems of power equations, using auxiliary hidden groups. This allows the number of equations to be equal to or greater than the number of unknowns, thereby ensuring resistance to potential attacks based on equivalent keys. Using this approach, an algorithm has been developed that is of practical interest due to the small combined size of the public key and signature.
