Given enough computer power, desire, brains and some luck, the security of most systems can be broken. But there are cryptographic and algorithmic security techniques, ideas and concepts out there ...

As a graduate student at the Massachusetts Institute of Technology in 1996, Amit Sahai was fascinated by the strange notion of a “zero-knowledge” proof, a type of mathematical protocol for convincing ...

The ease at which criminals can reverse engineer software makes for lucrative transgressions with national security implications, prompting government-backed researchers to seek innovations to shore ...

Researchers with a DARPA-led team are looking into new ways to combat reverse engineering by using obfuscation to tidy up shoddy commercial and government security. Researchers with a DARPA-led team ...

Program obfuscation aims to compile a program to make it unintelligible in order to hide the logic and knowledge in the original program. Methods for program obfuscation have been long sought-after in ...

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 ...

The quest for unbreakable encryption may have finally succeeded. A team of researchers has created a tool capable of making any program impervious to attacks. Share on Facebook (opens in a new window) ...

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 ...

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 ...
