Facebook to Adopt Encryption Technology
Will help safeguard communications from surveillance
Revelations about the National Security Agency's surveillance abilities have highlighted shortcomings in many Internet companies' security practices that can expose users' confidential communications to government eavesdroppers.
Secret government files leaked by Edward Snowden outline a U.S. and U.K. surveillance apparatus that's able to vacuum up domestic and international data flows by the exabyte. One classified document describes "collection of communications on fiber cables and infrastructure as data flows past," and another refers to the NSA's network-based surveillance of Microsoft's Hotmail servers.
Most Internet companies, however, do not use an privacy-protective encryption technique that has existed for over 20 years—it's called forward secrecy—that cleverly encodes Web browsing and Web e-mail in a way that frustrates fiber taps by national governments.
