Twitter beefs up security - takes pointers from spies
Twitter has used an "impossible" mathematical problem first discovered by a British secret agency to protect its users from electronic snooping.
The company said "perfect forward secrecy" (PFS) was now live on all its services, drastically increasing the effort required to intercept its traffic.
It was understood the move is intended to make it more difficult for data to be collected on its users without going through legal channels. Jim Killock, director of the Open Rights Group (ORG), said it was a "policy move" driven by revelations about mass surveillance by British eavesdropping agency GCHQ and the American National Security Agency (NSA).
