COMMENTARY--I can imagine a world where the computers needed no security. Where there were no passwords, no security checks, and no firewalls. Where the computers communicated freely and shared ...

A cryptographic master tool called indistinguishability obfuscation has for years seemed too good to be true. Three researchers have figured out that it can work. A recent cryptographic breakthrough ...

There are plenty of tools out there that can decompile compiled assemblies and retrieve the original source code. These decompilers are a threat to your intellectual property, making it imperative ...

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 ...
