Cryptography – The Conversation

Computer capabilities have boosted our decryption technology to great heights. How will the future compare to a past, one in which codes were thought to be a means of communicating after death?

NFTs are made the same way as crypto coins, but where every crypto coin is like every other, each NFT is a unique digital item – from images to sound files to text.

Many Australians are unaware of current police and intelligence powers when it comes to accessing our data.

Blockchain technology is familiar to us in the form of digital currency bitcoin. And if it makes it way to the mainstream, could it change the way the world does business forever?

A flawed paper shakes confidence in the foundations of ‘quantum-proof’ encryption – and highlights the need for a new generation of experts.

Australians vote on a piece of paper and put that into a box which is then counted. We don’t know how to replicate this transparent, verifiable process over the internet.

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.

Researchers tried several times to have the document declassified, including in 1992, 2004 and 2016. It was initially written to help American NSA agents crack difficult coded messages.

The Voynich Manuscript has researchers, the media, and the public hooked. But pseudo-explanations for the book’s ‘code’ reveals a serious problem with society’s relationship with science.

More profitable applications for quantum computers are eclipsing the drive to break encryption.

A paper published by researchers at Google claimed that they had achieved computing quantum supremacy, but leaks and counter-claims have created a stir.

The news that a certain class of cryptographic algorithms just got 20 times easier to hack has set hares running.

Quantum hardware and software are advancing rapidly – and our online encryption systems need to change to stay ahead.

Habsburg emperor Rudolf II owned a spirit-summoning alchemical hand bell. We want to decipher its cryptic Greek inscriptions.

A major focus of the federal government’s defence policy update is the need to develop quantum-based defence technology that will help Canada address two big threats: the Arctic and cyber security.

Pacemakers are Internet of Things devices for the human body, but they’re still not particularly secure.

The secret recipe came from Arthur Dee, 17th-century alchemist and royal physician to the Tsar.

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.

A mathematician explains how language can keep your online accounts safe and pinpoint your location on the planet.
