Abstract
A first electronic network node () is provided configured for a key exchange (KEX) protocol, the first network node is configured to obtain a shared polynomial (a) shared with a second network node, coefficients of the shared polynomial a being selected modulo a first modulus q, generate a private key polynomial (sk), coefficients of the private key polynomial being bounded in absolute value by a bound (s) generate a public key polynomial (pk) by computing a polynomial product between the shared polynomial (a) and the private key polynomial (sk) modulo the first modulus (q) and scaling the coefficients of the polynomial product down to a second modulus (p).
