Analytical Thinking
Structural Logic Core Contribution: This paper investigates the GMLHRSP
Attention to Detail problem, which is a modification of the post-quantum
Fast Learner MLHRSP problem using modular arithmetic over a
Problem-Solving generalized Mersenne number. A modification of the Zheng-
Time Management Yang attack based on the LLL lattice reduction algorithm has
been constructed. It is shown that the transition to arithmetic
modulo a generalized Mersenne number does not eliminate
Languages the problem’s vulnerability to this type of attack, while
preserving the necessary constraints on the problem’s
