[ NNSquad ] Computing On Encrypted Databases Without Ever Decrypting Them 

Computing On Encrypted Databases Without Ever Decrypting Them

http://j.mp/w0NLE3  (Forbes)

   "Now the Google- and Citigroup-funded work of three MIT scientists
    holds the promise of solving that long-nagging issue in some of the
    computing world's most common applications. CryptDB, a piece of
    database software the researchers presented in a paper (PDF here) at
    the Symposium on Operating System Principles in October, allows users
    to send queries to an encrypted set of data and get almost any answer
    they need from it without ever decrypting the stored information, a
    trick that keeps the info safe from hackers, accidental loss and even
    snooping administrators. And while it's not the first system to offer
    that kind of magically flexible cryptography, it may be the first
    practical one, taking a fraction of a second to produce an answer
    where other systems that perform the same encrypted functions would
    require thousands of years."

CryptDB: Protecting Condentiality with 
Encrypted Query Processing 

http://j.mp/u1INfV  (MIT [PDF])

   "It works by executing SQL queries over encrypted data using a
    collection of efcient SQL-aware encryption schemes. CryptDB can
    also chain encryption keys to user passwords, so that a data item
    can be decrypted only by using the password of one of the users
    with access to that data. As a result, a database administrator
    never gets access to decrypted data, and even if all servers are
    compromised, an adversary cannot decrypt the data of any user who
    is not logged in."

Potentially a *very* big deal.
