While many computer scientists had long given up on the possibility of establishing indistinguishability obfuscation (iO), a master tool for encryption, UCLA Samueli computer science graduate student Aayush Jain and his adviser, Professor Amit Sahai, have not. Sahai, in particular, has spent more than 20 years trying to solve this elusive problem.

Working with Huijia Lin, a professor at the University of Washington, Jain and Sahai created an iO protocol circumventing the complications that prevented past attempts from making iO a reality. Forbes published today an article titled “Cryptographers Unveil Breakthrough In Achieving Indistinguishability Obfuscation,” which featured the group’s recently published research that solved the decades-long mystery. Quanta Magazine also published an article last month titled “Computer Scientists Achieve ‘Crown Jewel’ of Cryptography.”

If successfully launched, iO could render a computer program unintelligible while preserving its functionality. Obfuscating a computer program allows for an array of useful applications, such as “deniable” encryption, which allows a user to fend off potential attacks, and “functional” encryption, which enables a user to specify the level of data access. While the protocol is not yet ready to be deployed, it could eventually provide pathways for a myriad of cryptographic tools that were not previously available.
