Cayley–Purser algorithm
The Cayley-Purser algorithm was published in early 1999 by Irishwoman Sarah Flannery, who was sixteen years old at the time. She named the cryptographic algorithm for mathematician Arthur Cayley and Michael Purser, founder of Baltimore Technologies, a Dublin data security company. Flannery had the idea for the algorithm during an internship with Baltimore Technologies.
The Cayley-Purser algorithm should have been some 22 times faster than the RSA process, because it uses a simpler mathematical function. For her work, Flannery received first prize in an Irish competition for young scientists. She subsequently discovered an attack on her algorithm, but she analyzed it and included it as an appendix in later competitions, including a Europe-wide competition in which she won a major award.

The Cayley-Purser algorithm is famous, because it was orginally announced that is was a Public-key but it is really a Private-key(one-key,Symmetric key algorithm) cryptosystem, because too much information is leaked in the Cayley-Purser algorithm. -Sarah Flannery, "In Code" It can not securly function as a public and private key cryptosystem.
