Levison said moves to allow government access to encrypted data would weaken safety online for everyone. “Think how much information has been stolen online already in the last year,” he said, referring to the hacks of Sony, Target and Home Depot. Creating “backdoors” for US or UK authorities would make the entire system more vulnerable, he insisted.
“Encryption underpins the entire network of trust on the internet, from downloading applications to banking and software updates,” said Levison. “If you have to hand over the keys, you’d be well advised not to use some services,” he said.
Levison’s comments came as the Guardian published details of a newly uncovered 2009 document from the US National Intelligence Council that called
encryption the “best defence” for computer users to protect private data.
