NSA Suite A Cryptography: Security through obscurity? I think you're misunderstanding, or maybe misapplying Kerchoffs's Principle. "A cryptosystem should be secure even if everything about the system, except the key, is public knowledge." just means that you shouldn't be relying on the secrecy of the algorithm for security. Keeping the algorithm a secret may (or may not) increase security, but it can't be required for a particular level of security. NSA designs their algorithms under the assumption that opponents know how they work. They don't publish them so as to not make it any easier on the bad guys than they have to. |
