Indistinguishability obfuscation is a cryptographic primitive that provides a formal notion of program obfuscation. It has been flagged as nonexistent by skeptics and deemed impossible to achieve. In a paper titled “Indistinguishability Obfuscation from Well-Founded Assumptions,” UCLA Computer Science Graduate Student Aayush Jain, Professor Amit Sahai, and Huijia Lin of the University of Washington show that it is possible to build indistinguishability obfuscation using only standard security assumptions. Theoretically, this paper contributed a means to build different cryptographic tools based on indistinguishability obfuscation.
