Ring Learning With Errors for Key Exchange (RLWE-KEX)

Public key and key exchange methods which use Diffie-Hellman, Elliptic Curve, RSA and El Gamal will be cracked by quantum computers. In order to overcome this we need new methods which are quantum robust. One of these methods is Learning With Errors (LWE). With RLWE we use the learning with errors (LWE) method but add polynomial rings over finite fields.
