In response to criticism of the proposed laws, Prime Minister Malcom Turnbull insisted that while “the laws of mathematics are very commendable … the only law that applies in Australia is the law of Australia.”
However, this focus on empowering law enforcement tends to ignore not just the laws of mathematics and the fundamentals of encryption technology, but also the fact that undermining encryption would do real harm to ordinary Australian citizens and businesses. Communication tools and services that feature end-to-end encryption are now an essential part of most Australians’ daily routine.
