But I've been blogging over here for a while now, mostly infosec stuff.

Thanks for the blog link

I've always had an interest in security. I think that it started with the Scientific American article about trapdoor ciphers, back in the late seventies IIRC.

BTW, you were not the only circle person at RSA.

Thanks, I hope you like it.

Yeah, I should have posted that I was going to be at RSA, I didn't even think about it. I usually do that on the various infosec mailing lists I'm on.

Trapdoor cipher? We call that a hash nowadays, right?

The article was prompted by the original Rivest, Shamir, and Adelman paper on public-key cryptosystems. It was in Martin Gardner's [wikipedia.org] Mathematical Games column (see the bullet list under Recreational Mathematics in the linked article). I wrote for and received a copy of the paper, but I no longer know where it is.

The name "trapdoor cipher" referred to some kind of operation that is easy to perform in one direction (like multiplication), but hard to perform in the other (factoring). That is distinct from a h

Gotcha, thanks.
