I'm thinking the canonical example of an open network is Bitcoin. Here, everyone knows the public key and could potentially crack the private key from it (for enormous gain obviously). Just do the same thing with a sufficiently large AES key for example.
- lxgr 3y agoWhere’d you store that key securely, though? It’s passwords all the way down (unless you use smartcards or tokens).
- osigurdson 3y agoI think if I had one key as the root to all others (just like LastPass basically), it could be manageable.
- lxgr 3y agoPractically, how would you do it? Memorable passwords unfortunately have really low entropy.
