Cryptographic obfuscation and functional encryption have emerged as pivotal tools in contemporary cryptography, offering novel ways to secure software and data while preserving functionality. At its ...

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 ...

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 ...

A new paper titled "Indistinguishability Obfuscation from Well-Founded Assumptions" may have unlocked a decades-old encryption puzzle. Is it possible to encrypt a computer program such that the code ...

ACM, the Association for Computing Machinery, today announced that Aayush Jain receives the 2022 ACM Doctoral Dissertation Award for his dissertation “Indistinguishability Obfuscation from ...

Researchers say their new software obfuscation scheme is the first time this technique has been successfully accomplished where the underlying piece of software, such as a patch, could not be reverse ...

The method was called “indistinguishability obfuscation,” or IO. The authors touted it as a “central hub” for all of cryptography—a unified basis upon which to reconstruct familiar cryptographic tools ...

Disclosure: the author of this article is involved with the Ethereum project. There have been a number of very interesting developments in cryptography in the past few years. Satoshi’s blockchain ...
