It's only a matter of time before any existing cryptographic method is cracked.

On the plus side, this seems to take longer than it does to invent good, new ones.

Why not keep the SSH or Tor protocol on a rolling update schedule, like web browsers? Encryption methods should expire just like passwords.

Counterintelligence seems like a good way to create a reliable job market for cryptography experts.

Obviously this is what secret agencies already do, but the commercial market could churn out new standards frequently with enough heads involved, flawed though they might end up being.

Analogy to a one-time pad, maybe?
