Greens Digital Rights spokesperson Jordon Steele-John said in a statement he was concerned the proposed law would simply make it mandatory for firms to hand over the content of encrypted data, absolving the government of compromising that data.
Taylor was on Radio National on Wednesday morning speaking about the encryption legislation, but refusing to offer any detail when asked.
Home Affairs Minister Peter Dutton had said earlier this year that the government would force companies that provide encryption for communications to devise a means of giving government agencies access to encrypted messages.
“This is extremely problematic whichever way you look at it because if end-to-end encryption is working properly, then you are legislating (and asking) companies to do the impossible. There is no method of accessing data if it has been properly encrypted.
“Companies will be forced to undermine their own encryption in order to comply with Australian law, therefore undermining the privacy and security of user’s data.'
In March, the Senate approved a motion from the Greens to support strong encryption, resist pushes to undermine encryption, and to use warrants and targeted surveillance to obtain information.
"Quite simply this will necessitate surveillance codes, key escrow or some other ‘backdoor’ methodology of decrypting data to allow it to be handed over if the Australian Government produces a warrant," Senator Steele-John said.
“It also allows this Liberal Government to continue to lie through their teeth to the Australian people by saying that they won't legislate companies to undermine their own encryption.
"It really is a case of the laws of maths not applying in Australia if you bury your head far enough in the sand!
“Minister Taylor needs to detail how he proposes to access encrypted data, or else come clean to the Australian people that their online information will be compromised.”
