Fourteen of the world's pre-eminent cryptographers and computer scientists have put together a report which concluded that the British and American governments cannot demand special access to encrypted communications without putting the world's most confidential data and critical infrastructure in danger.

The report states that "Such access will open doors through which criminals and malicious nation-states can attack the very individuals law enforcement seeks to defend…The costs would be substantial, the damage to innovation severe and the consequences to economic growth hard to predict. The costs to the developed countries’ soft power and to our moral authority would also be considerable".
