researchers presented at the Symposium on Operating System Principles in
October, allows users to send queries to an encrypted SQL database and get
results without decrypting the stored
information<http://www.forbes.com/sites/andygreenberg/2011/12/19/an-mit-magic-trick-computing-on-encrypted-databases-without-ever-decrypting-them/>.
CryptDB works by nesting data in several layers of
cryptography<http://people.csail.mit.edu/nickolai/papers/raluca-cryptdb.pdf>
(PDF),
each of which has a different key and allows a different kind of simple
operation on encrypted data. It doesn't work with every kind of
calculation, and it's not the first system to offer this sort of
computation on encrypted data. But it may be the only practical one. A
previous crypto scheme that allowed operations on encrypted data multiplied
computing time by a factor of a trillion. This one adds only 15-26%."**
