Abstract
Some embodiments relate to a first electronic network node is provided () configured for a cryptographic operation. The first network node is configured to receive as input a difficulty parameter (d), and a structure parameter (n), and to obtain a shared matrix (A), the shared matrix being shared a second network node through a communication interface, entries in the shared matrix (A) being selected modulo a first modulus (q), the shared matrix (A) being a square matrix (k×k) of dimension (k) equal to the difficulty parameter (d) divided by the structure parameter (n), the entries in the shared matrix (A) being polynomials modulo a reduction polynomial (ƒ) of degree equal to the structure parameter (n), said cryptographic operation using the shared matrix.
