Abstract

Un primer nodo de red electrónica (110) se proporciona configurado para un protocolo de intercambio de claves (KEX), el primer nodo de red se configura para - obtener una matriz compartida (A) compartida con un segundo nodo de red, siendo las entradas en el módulo de matriz compartida A que se seleccionan un primer módulo q, - generar una matriz de clave privada (SI) estando las entradas en la matriz de clave privada limitadas en valor absoluto por un límite (s) - generar una matriz de clave pública (PI) mediante - calcular un producto de matriz entre la matriz compartida (A) y el módulo de la matriz de clave privada (SI) el primer módulo (q) y reducir las entradas escaladas en el producto de matriz a un segundo módulo (p).
