Plus this result is not that surprising in my opinion. "We cannot think of all possible algorithms to attack a system, and thus, systems might be insecure and we do not know how." Well, duh. Complexity theorists say "We might be able to solve NP-problems in P, but no one knows how. We might be able to factorize primes faster, but we don't know how." So... this fact is not that surprising.
