Today we’re going to talk about how to keep information secret, and this isn’t a new goal. We’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard ...

In 2018, Aayush Jain, a graduate student at the University of California, Los Angeles, traveled to Japan to give a talk about a powerful cryptographic tool he and his colleagues were developing. As he ...

New techniques could stand up to the power of a quantum computer — if we implement them in time New techniques could stand up to the power of a quantum computer — if we implement them in time In 2016, ...

Like many nerds, I have an interest in cryptography rooted in the wartime exploits of codebreaker and Ur-computer scientist Alan Turing. So I’ve followed with interest IEEE Spectrum’s reporting on the ...

What do the Gallic Wars and online shopping have in common? The answer, believe it or not, is cryptography. Cryptography is the cement of the digital world, but it also has a long history that ...

More than a decade ago, I was giving an introductory presentation on quantum cryptography, as I had done many times before. I discussed the basic concepts of quantum physics, quantum computers, and ...

A consortium of companies led by Airbus has been established by the European Commission (EC) to study the design of future European quantum communications. The commission plans to develop an ...

Post-quantum cryptography will be a major challenge for the next decade at least, according to Bart Preneel, professor of cryptography at KU Leuven University in Belgium. This is one of the main ...

Key takeawaysButerin sees a nontrivial 20% chance that quantum computers could break current cryptography before 2030, and he argues that Ethereum should begin preparing for that possibility.A key ...
