Diamond iO: A New Path to Practical Program Obfuscation

Obfuscation (Part II): Diamond IO

I explore Diamond iO, a novel cryptographic approach that significantly reduces the runtime of program obfuscation from galactic to planetary scales. By modifying the BGG+14 attribute-based encryption scheme and integrating fully homomorphic encryption, this method offers a more feasible path to hiding secret keys within executable programs while maintaining security.

The biggest downside of these protocols so far has been their literally galactic runtime - if you actually try to figure out how long it would take to run one of them, you would get an answer longer than the lifetime of the universe.
