Broken Keys

Encryption is the only real tool we have right now to protect our private communications from prying eyes or our valuable business plans from being stolen.  Or, to put it simply, encryption is our lock and key to keep people out of our stuff.

BUT a New York Times article this week reported that the strongest encryption we have actually has a significant flaw.  http://www.nytimes.com/2012/02/15/technology/researchers-find-flaw-in-an-online-encryption-method.html.   The encryption algorithm starts by RANDOMLY selecting two very large prime numbers and uses these as the basis to create the public and private keys.  Unfortunately, scientists have proven that in some cases the selection is not truly random - i.e. it could be predictable.  And they say that means "2 out of every 1000 keys would not be secure".  Wow!  That's scary . . . and makes me think what other encryption methods are not as solid as we thought?

Your job is to find an article that deals with encryption AND something going wrong.   You could try these words in your search with ENCRYPTION or CRYPTOGRAPHY: weakness or vulnerability or hack or broken or RSA. In your posting, give a minimum 3 sentence summary of the article and be specific about what went wrong with this encryption method.
