Less and less of today's computing is done on desktop computers; cloud computing, in which operations are carried out on a network of shared, remote servers, is expected to rise as the demand for computing power increases. This raises some crucial questions about security: Can we, for instance, perform computations on data stored in 'the cloud' without letting anyone else see our information? Research carried out at the Weizmann Institute and MIT is moving us closer to the ability to work on data while it is still encrypted, giving an encrypted result that can later be securely deciphered. http://phys.org/news243164223.html Technology Thu, 15 Dec 2011 09:37:09 EST news243164223 (PhysOrg.com) -- A joint U.S./UK research team has found that common encryption techniques are so good that law enforcement, from local to highly resourceful federal agencies, are unable to get at data on a computer hard disk that could be used to prove the guilt of people using the computer to perpetuate crimes. In looking at the current technology, the team, as they describe in their paper published in Digital Investigation, find that if criminals use commonly available hard drive encryption software, law enforcement very often is unable find anything that can be used against them. http://phys.org/news241086969.html Electronics Mon, 21 Nov 2011 08:36:32 EST news241086969
