The RSA Challenges  RIP
There are no more prizes to give out and/or get a confirmation of the correct answer from RSALabs, the RSA Factoring and RSA SecretKey challenges have all been recently cancelled.

How does this follow?
PS: Maybe this means all the silly people who try to factor RSA numbers using trial division will finally go away (though in truth there weren't that many to begin with; even PrimeGrid is doing a little useful work) Last fiddled with by jasonp on 20070521 at 12:55 Reason: added venom

(1) Someone informed the company that he/she has developed a fast factoring algorithm. i.e. The company no longer has confidence in the security of the RSA algorithm. (2) Someone in the EMC management chain decided that they did not want to carry the liability. (3) They have decided that the algorithm has had enough scrutiny. (4) Randomness. I will leave for others to decide whether the cancellation says anything about EMC's confidence in the RSA algorithm. I am only guessing, but I regard (2) as most likely.

factorises the rest of the challenge numbers? This is unlikely to happen unless (1) happens. Last fiddled with by Visu on 20070526 at 07:15
