When the news first broke about Sarah Flannery's work on
morphing RSA into matrices defined over finite fields, I
mentioned that I had seen a similar paper earlier. Brian Winkel,
the editor of Cryptologia, did some digging for me and found the
piece in the April 85 issue. It was by Vijay Varadharajan and R.
Odoni. The title was "Extenison of RSA Cryptosystems to Matrix
Rings". I've read a copy of the paper and it doesn't seem to
explicitly describe the work of Flannery et al, but I can't be
certain because there aren't too many public details from
Ireland yet.

If anyone has read the paper or similar work, I would be
interested in your comments.
