"R. Steve Walz" wrote in message
Nothing CAN magically guess extraordinarily long primes. That will never just magically become possible. This intrinsic truth resides in the very mathematics itself, a fact outside of time and progress, and not in any technology of any kind. That's true now, but only to a point. That point is the advent of quantum computing, which allows you to effectively solve for all the possible factors in very little time (say 10^500 times faster than conventional computing for this sort of problem). If QC happens, large prime number encryption is crackable in a matter of seconds. And there is at least some reason to beleive that QC is achievable within a couple of decades. OTOH, the real danger in the near- to mid-term is not crypto-system attack, but physical compromise of the crypto-system (the adversary getting hold of the both the mechanism and the keys themselves). If they have the actual keys, the eavesdroppers can decode RSA just as easily as the intended recipients. -- Tom Schoene Replace "invalid" with "net" to e-mail "If brave men and women never died, there would be nothing special about bravery." -- Andy Rooney (attributed) |

Assume these double every 18 months. 10 years is about 7 doublings so in 2003 we'll see PCs with 250 GHz CPUs and 32 GB of RAM. Right. you are going to base national security matter on a rule of thumb that relates to a typical PC. Good move. |

Just an escalation, the power of operations easier one way than the other persists and an increase in length results in the same safety. For it to be otherwise you need to postulate that the govt will be doing its own fundamental research, and it NEVER does, and that it will develop QC to that level BEFORE the market sells it or the people developing it steal it and spread it around to prevent a national monopoly on power, and that's pretty unlikely.

Of course RSA is uncrackable, just like the good Admirals systems and I assume he had a lackwitted buffoon just like you telling him that there was no way anyone could be decrypting our stuff too... --------------------------- That's irrelevant, because he would have simply been technically wrong out of his own ignorance of cryptology, whereas I am not. -Steve -- -Steve Walz ftp://ftp.armory.com/pub/user/rstevew Electronics Site!! 1000's of Files and Dirs!!

Adam" wrote: In message , Greg Hennessy Since this was a demonstration rather than a formal like-for-like trial, the MoD refused to specify the other weapons or their performances. One wonders why. However, IDR's own sources indicate that among those taken were the Diemaco C7 version of the M16A2 (as used by the UK SAS and SBS), the Heckler & Koch G36, and the Steyr AUG. Strange that, one must assume there was an 'improved' version of the SA80 available for spanish army trials last year, one wonders how if it faired there if at all. It is understood whichever alternative weapon they used, none of the participants was able to match the SA80 A2 in either accuracy or reliability during this demonstration. Until there is independently verified proof of such assertions one is inclined to take them with a large shovel of NaCL. THe MOD has now wasted the price of 4 alternatives on each and every weapon so far. It wouldn't be the 1st time one has heard the usual 'its working now honest' honest from them. I have received some comments from British soldiers returing from Iraq. They had no complaints about the L85A2 performance. You can be certain that after the huge - and seriously over-hyped - press row about alleged early 'failures' of this weapon (see: http://www.navynews.co.uk/articles/2...1002111301.asp for what REALLY happened), we would certainly have heard of any problems. One commment was that the compact bullpup layout was much handier than the much longer M16 when travelling in vehicles such as Land Rovers, and it also helped to have the magazine more inboard. Quite a contrast with the various news items about the jamming of M16s, M249s and even the .50 M2...

Historically, each and every crypto shop has been sublimely convinced that_its_cypher was unbreakable. As near as I can tell, each and every one of them was wrong. What makes that conviction so remarkable is that most crypto shops either were breaking or had allies who had broken the opposition's codes. After the Walker Ring compromised US Naval codes and KGs for years, I read an article in USNI Proceedings by a communications specialist who airily waved that damage away with "we've changed all the keys". There are more ways than brute force to break COMSEC. |
