re pgp general comments neuhaus vier informatik uni kl de stephan neuhaus hiwi mattern writes lots of stuff i hate to follow up to my own posting but i should perhaps clarify some things so i won t get flamed first of all when i m talking about factoring the modulus or a breakthrough in factoring what i really mean is a breakthrough in the cryptanalysis of rsa i know that factoring and breaking rsa are not proven to be equivalent it s just so damn convenient not to repeat this every time i also have to admit that i don t really know if the non group property of a cipher is essential only for key chaining i have thought about it a little while but i can t find a way that a cryptanalyst could exploit a group structure that of course means nothing at all then i wrote please note that as long as it is much harder to factor a rsa modulus than it is to generate it the increase in computer speed alone will keep key lengths and modulus factoring in lock step i e people will simply start using longer moduli and still be safe what i meant was that as long as the only advantage of the cryptanalyst is a faster computer then we will probably have rsa for a long time to come because even if bit moduli somehow could be broken with fast computers not with a new algorithm then people would simply use longer moduli both users and cryptanalysts benefit from better technology in the same way hope this keeps the flames away have fun stephan neuhaus informatik uni kl de sig closed for inventory please leave your pickaxe outside pgp public key available on request note the expiration date
