[sci.crypt] Factorising large numbers.

howellg@idec.UUCP (02/11/87)

On Monday I heard on the programme "Science Now", on BBC Radio 4,
about a new algorithm for factorising large numbers using the
properties of "nice primes".  I think the algorithm was generated in
Holland, but as I was in the car at the time I wasn't able to give the
item the attention I would have liked.

Does anybody in "net-land" know anything about this new algorithm and
the impact it is likely to have on the security of PKCs like RSA?
or is this just the new Lenstra algorithm that has been discussed
recently in this group?

	Cheers	Gareth

Yep, 'fraid it was the Lenstra algorithm. 

Apprarently BBC Radio Producers read Nature too!
