It is hard to predict when quantum computers will be strong and fast enough to crack the codes that keep bitcoin safe. But that day is coming.
Prime numbers are a mathematical mystery.
Crypto cash is catnip for criminals and a huge challenge to law enforcement – so it's time to bring in a tough, jurisdiction-busting regulatory body.
Scholars dig in to the debate on whether police should be able to defeat or circumvent encryption systems.
Many Australians are unaware of current police and intelligence powers when it comes to accessing our data.
Pacemakers are Internet of Things devices for the human body, but they're still not particularly secure.

Apple's design decisions don't please everyone, but in the iPhone the company created something truly revolutionary that has lasted.
The first line of cyberdefense is having a good password. What does research say about what that actually means?
The technical consensus is clear: Adding 'backdoors' to encryption algorithms weakens everyone's security. So what are the police and intelligence agencies to do?
A new way to generate random numbers can improve mathematics, cybersecurity and even predictions about the future. How does it work, and what does it mean for us?

The battle between personal privacy and national security online continues.
We increasingly depend on algorithms applied to big data, but even algorithms make mistakes that could label us in worrying ways
With attacks against Tor increasing, prototype anonymising software Vuvuzela takes a different approach.
University researchers broke Tor, briefly, to bring down Silk Road 2.0, and this matters.
The government's Defence Trade Controls Act effectively makes teaching encryption a criminal act and considers even a simple calculator as a potential weapon.
A word of advice: don't try and build your own cryptography. It's hard and others have done it better.
Online voting could boost turnout, but a flawed system could destroy faith in the voting process.
Encryption has come a long way since the days of Sparta and Rome, but it's still not 100% secure.
