"Will it Crack?", by Charles Seife. *New Scientist,* 23 January 1999 page20.

"Irish Lass Invents Crypto Code". Random Samples, *Science,* 29 January1999, page 599.

The mathematical project of a 16 year old from Ireland may provide a faster way to encrypt information sent via the Internet. These articles introduce Sarah Flannery and the encryption scheme she helped develop. The scheme uses public key cryptography -- a method which relies on mathematical operations that are difficult to undo -- and is significantly faster than the predominantly used RSA algorithm.
