Claim 12:
13. The method according to claim 12, further comprising:
determining the deterministic key (DK) based on determining a hash of a message (M), and
wherein the step of determining a first node second private key (V2C) is based on a scalar addition of the first node master private key (V1C) and the deterministic key (DK) according to the formula:

V2C=V1C+DK, and

wherein the step of determining a second node second public key (P2S) is based on the second node master public key (P1S) with elliptic curve point addition to the elliptic curve point multiplication of the deterministic key (DK) and the common generator (G) according to the formula:

P2S=P1S+DK×G.
