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 ...

The day when a quantum computer can crack commonly used forms of encryption is drawing closer. The world isn’t prepared, ...

Quantum computers are coming. And when they arrive, they are going to upend the way we protect sensitive data. Unlike classical computers, quantum computers harness quantum mechanical effects — like ...

Random number generators have been around for ages, but they often have subtle imperfections that cause patterns to emerge.

Online data is generally pretty secure. Assuming everyone is careful with passwords and other protections, you can think of it as being locked in a vault so strong that even all the world’s ...

A long-sought “holy grail” in cryptography is poised to change the way we protect sensitive information. Today’s standard encryption schemes take an all-or-nothing approach. Once scrambled, your data ...

We all know to be careful about the details we share online, but the information we seek can also be revealing. Search for driving directions, and our location becomes far easier to guess. Check for a ...

As computer scientists tackle a greater range of problems, their work has grown increasingly interdisciplinary. This year, many of the most significant computer science results also involved other ...
