Quantum Computer Not Ready To Break Public Key Encryption For At Least 10 Years, Some Experts Say (theregister.co.uk)
physburn writes: The Register has spoken to some experts to get a better understanding of the risk quantum computers present to the existing encryption systems we have today. Richard Evers, cryptographer for a Canadian security biz called Kryptera, argues that media coverage and corporate pronouncements about quantum computing have left people with the impression that current encryption algorithms will soon become obsolete. But they will not be ready for at least 10 years, he said. As an example, Evers points to remarks made by Arvind Krishna, director of IBM research, at The Churchill Club in San Francisco last May, that those interested in protecting data for at least ten years "should probably seriously consider whether they should start moving to alternate encryption techniques now." In a post Evers penned recently with his business partner Alastair Sweeny, he contends, "The hard truth is that widespread beliefs about security and encryption may prove to be based on fantasy rather than fact." And the reason for this, he suggests, is the desire for funding and fame.
Sure, do you remember when DES was going to take the lifetime of the Universe to crack, then some egg-heads had custom ASICS fabbed and built Deep Crack (EFF DES Cracker), which could break DES in a day?
No, I don't remember that for two reasons the most important being that nobody sane ever made such an idiotic claim. In fact in the wikipedia page linked by yourself (that you obviously didn't read) contains this: "One of the major criticisms of DES, when proposed in 1975, was that the key size was too short. Martin Hellman and Whitfield Diffie of Stanford University estimated that a machine fast enough to test that many keys in a day would have cost about $20 million in 1976, an affordable sum to national intelligence agencies such as the US National Security Agency".
So not only didn't anybody make your ludicrous claim but people at the time said it was too easy to crack and estimated that one could realistically build a DES cracker.
