DETERMINING A COMMON SECRET FOR THE SECURE EXCHANGE OF INFORMATION AND HIERARCHICAL, DETERMINISTIC CRYPTOGRAPHIC KEYS (patentscope.wipo.int)

A method (300) and system (1) of determining a common secret for two nodes (3, 7). Each node (3, 7) has a respective asymmetric cryptography pair, each pair including a master private key and a master public key. Respective second private and public keys may be determined based on the master private key, master public key and a deterministic 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…

Looks like bitcoin is poised for moon launch, is there anything I should be doing to secure my coins better?

Right now I keep most of my coins on an exchange, and i have my account secured with a solid password.
