From the Indistinguishability Obfuscation Wikipedia entry[0]: "Indistinguishability obfuscation (IO) is a cryptographic primitive that provides a formal notion of program obfuscation. Informally, obfuscation hides the implementation of a program while still allowing users to run it.[1] A candidate construction of IO with provable security under concrete hardness assumptions relating to multilinear maps was published in 2013.[2] However, the assumption used in this construction was later broken.[3] Later candidates, including the 2020 work of Aayush Jain, Huijia Lin, and Amit Sahai, rely on more standard assumptions.[3]" The paper linked in the title is the 2020 work by Jain, Lin and Sahai referenced above.
