Titolo: RSA e 16enne

Se avete il televideo a pag 149 ci 
trovate lo "scoop" completo.
Pare che una 16enne sia riuscita a potenziare l'RSA
utilizzando un algoritmo + efficace e + veloce .
Ora la domanda nasce spontanea : 
ammettiamo che l'algoritmo sia stato fatto 
da questa ragazza 
(cosa che mi lascia molto perplesso )
come fanno a dire che è + sicuro dell'RSA  in un tempo
cosi' breve ?
non ci vogliono degli anni e dei buoni crittoanalisti per
verificare la robustezza dell'algoritmo ?
La Duchessa che gli scoop come questo sembrano dei
tentativi grossolani per  fregare il prossimo

Ciao a tutti, posto l'articolo che ho trovato su:

Teenager's email code is a
             cracker
             The prize judges could not completely understand the
"brilliant" code
             Making your email secret is now 30 times faster, but the
             innovation has come not from a multinational computer
             computer but a schoolgirl from Blarney, Ireland.
             Sarah Flannery, 16, has developed a brand new
             mathematical procedure for encrypting internet
             communication.
             "It is a public-key algorithm and is based on matrices,"
             her father told BBC News Online. Dr David Flannery is a
             mathematics lecturer at Cork Institute of Technology,
             Ireland.
             "Sarah has a very good understanding of the
             mathematical principles involved, but to call her a genius
             or a prodigy is overstated and she doesn't want that
             herself.
                                 "She's a normal young girl,
                                 who likes basketball and
                                 going out with her friends."
                                 International job offers
                                 But her number-crunching
                                 feat is undoubtedly
                                 remarkable and won her the
                                 top prize at the Irish Young
                                 Scientists and Technology
                                 Exhibition. She did a period
                                 of work experience with
                                 Baltimore Technologieslast
                                 April. And her cryptography
                                 skills also took her to Fort
             Worth, Texas, as the winner of an Intel prize.
             International job and scholarship offers have since
             flooded in, said Dr Flannery.
             Even when high security levels are required, her code
             can encrypt a letter in just one minute - a widely used
             encryption standard called RSA would take 30 minutes.
             "But she has also proven that her code is as secure as
             RSA," says Dr Flannery. "It wouldn't be worth a hat of
             straw if it was not."
             Ms Flannery currently has a bad cold and has not had
             time to consider the advice of the judges to patent the
             code. "She wouldn't mind being rich but she wants to
             stress the great joy that the project has given her," says
             Dr Flannery. She may publish the work to make it freely
             available to all.
             Her code is called Cayley-Purser after Arthur Cayley, a
             19th century Cambridge expert on matrices, and Michael
             Purser, a cryptographer from Trinity College, Dublin, who
             provided inspiration for Ms Flannery.
