Twitter Tightens Security Against Government’s Snooping

Twitter_LOGO

Twitter has hopefully made implementations of their new security measures that should make it much more difficult for anyone to eavesdrop on communications between its servers and users, and is calling on other Internet companies to follow its lead.

Twitter has implemented what it calls, “perfect forward secrecy” on its web and mobile platforms, it said Friday. The technology should make it virtually  impossible for any Government organization to eavesdrop on encrypted traffic today and un-crypt it at some point in the future.

At present, the encryption between a user and the server is based around a secret key held on the server. The data exchange cannot be read but it can be recorded in its encrypted form. Because of the way the encryption works, it’s possible to un-crypt the data at some point in the future should the server’s secret key ever be obtained.

With “perfect forward secrecy”, the data encryption is based on two short-lived keys that cannot be later recovered even with the knowledge of the server key, so the data remains secure.
