"Barr is calling for crypto that "achieve(s) a 99 percent assurance against cyber threats to consumers". We don't know how to build that... As the graphs above show, we only know how to build either 100% or 0%" [@ErrataRob, 26 July 2019]
"How hard is it to break this [end-to-end] encryption, for data encrypted to an up-to-date standard? It has been estimated to take 6,400,000,000,000 years using a 2009-era desktop computer. Supercomputers like China’s Sunway TaihuLight are up to three million times faster than that, and can perform 93 quadrillion calculations per second, so cracking a message might be possible in only 2 million years." [Australian Parliamentary Library, 3 October 2018]
This Twitter thread contains the best explanation of the digital disaster that the Abbott-Turnbull-Morrison Government has inflicted on Australian industry, businesses and consumers of digital products/services, by requiring government access to all encryption keys - mandated through the Telecommunications and Other Legislation Amendment (Assistance and Access) 2018 which became law on 9 December 2018.
The thread explains why there is no safe 'backdoor' to bypass up-to-date encryption on the basis of perceived national security or law enforcement needs.
So in today's tweet storm, let's discuss Barr's call for crypto backdoors, where he claims citizens don't need as strong crypto as the military: "After all, we are not talking about protecting the Nation’s nuclear launch codes". This is a fallacy, which I'll show with math.— Robᵇᵉᵗᵒ Graham (@ErrataRob) July 25, 2019
