Abstract: A method of establishing a secure channel for communication between a first computing device and a second computing de-vice is described. The method uses an elliptic curve Diffie-Hellman protocol, wherein G is an elliptic curve generator point and the first computing device has a unique private key de with a public key Q c =G  certified by a party trusted by the second computing device. The first computing device generates 520 a blinding factor r and sends 540 a blinded public key R = r. Q c to the second computing device. The second computing device generates 510 an ephemeral private key dt and a corresponding ephemeral public key Q t = d t G and sends Q t to the first computing device. The first computing device generates 530 K c= KDF (r d e. Q t) and the second computing device generates 550 K t = KDF (d t. R), where KDF is a key derivation function used in both generation operations, to establish a secure channel between the first computing device and the second computing device. G is a point in the elliptic curve group E, wherein E is a group of prime order but E* is the quadratic twist of E and is a group of order m = z. m' where m' is prime and z is an integer, wherein r. de is chosen such that z is a factor of r.  de.
