Claim 11:
12. The method according to claim 11, further comprising:
sending, over a communications network, to the second node, a notice indicative of using a common elliptic curve cryptography (ECC) system with a common generator (G) for the method of determining a common secret (CS), and
wherein the step of generating the first node master private key (V1C) and the first node master public key (P1C) comprises:
generating the first node master private key (V1C) based on a random integer in an allowable range specified in the common ECC system; and
determining the first node master public key (P1C) based on elliptic curve point multiplication of the first node master private key (V1C) and the common generator (G) according to the formula:

P1C=V1C×G.
