Super-pure silicon chips unlock next-generation computers

Silicon is so important for electronics and computing that it’s become synonymous with technology – even getting a valley named after it – but the stuff still has its flaws. Now, scientists have created a way to make super-pure silicon chips that could… Continue reading Super-pure silicon chips unlock next-generation computers

Surviving the “quantum apocalypse” with fully homomorphic encryption

In the past few years, an increasing number of tech companies, organizations, and even governments have been working on one of the next big things in the tech world: successfully building quantum computers. These actors see a lot of potential in the te… Continue reading Surviving the “quantum apocalypse” with fully homomorphic encryption

Apple Announces Post-Quantum Encryption Algorithms for iMessage

Apple announced PQ3, its post-quantum encryption standard based on the Kyber secure key-encapsulation protocol, one of the post-quantum algorithms selected by NIST in 2022.

There’s a lot of detail in the Apple blog post, and more in Douglas Stabila’s security analysis.

I am of two minds about this. On the one hand, it’s probably premature to switch to any particular post-quantum algorithms. The mathematics of cryptanalysis for these lattice and other systems is still rapidly evolving, and we’re likely to break more of them—and learn a lot in the process—over the coming few years. But if you’re going to make the switch, this is an excellent choice. And Apple’s ability to do this so efficiently speaks well about its algorithmic agility, which is probably more important than its particular cryptographic design. And it is probably about the right time to worry about, and defend against, attackers who are storing encrypted messages in hopes of breaking them later on future quantum computers…
