Each node (3, 7) has a respective asymmetric = cryptography pair, each pair including a master private key and a master = _ = — = Third node lc is 111 IOW public key. Respective second private and public keys may be determ- fined based on the master private key, master public key and a determin- —19 istic key. A common secret may be determined at each of the nodes based on the second private and public keys. In one example, a node (3, 7) may determine the common secret based on (i) a second private key based on the node's own master private key and the deterministic key; 3 = and (ii) a second public key based on the other node's master public key = = and the deterministic key. The invention may be suited for use with, but = — 27 not limited to, digital wallets, blockchain (e.g. Bitcoin) technologies and personal device security. t ti - 23 Second First node node = — '-'-r--' L \, Is _ 1-1 .4 11 kin ii- ,-1 IN ,-1 © ei Mc .
