Bruce Schneier: 'NSA and GCHQ have betrayed the trust of the internet'

Security expert and technologist Bruce Schneier has told the BBC that he believes the NSA and GCHQ have "betrayed the trust of the internet".

Mr Schneier said: "We have to trust the infrastructure [of the internet]... The fact that it has been subverted in ways we don't understand... we don't know what to trust. And that is an enormous blow to the global promise of the internet."

He added that the NSA's "collect-it-all" mentality is "not effective" but it is the way the "intelligence community operates".
