Encryption law changes will weaken the security of everyday Australians: expert

We're yet to see the details of the deal between the Government and Labor which would allow the passage of laws to give police and investigators access to encrypted messages.

That leaves one more day in this sitting of Parliament to get the laws through, after the Government claimed there was an urgent need to do so before Christmas.

One of the top cyber officials in Canberra, Alastair MacGibbon, head of the Australia Cyber Security Centre at the Australian Signals Directorate, used an interview on AM this morning to push back against critics who cite privacy concerns and fear big risks to cyber security. But many experts in the area remain unconvinced.

Riana Pfefferkorn is a cryptography fellow at the Stanford Centre for Internet and Society at Stanford University Law School and she joins PM. She gave extensive evidence to the parliamentary committee that assessed the Government's proposed legislation.
