Claim 30:
31. The system according to claim 25, wherein the first processing device is configured to:
determine the deterministic key (DK) based on a hash of the message (M), and wherein:, the 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

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

P2S=P1S+DK×G.
