A process that enables a computer program to hide not just collections of data but the inner workings of itself.


  • One long term goal is to create a computer program with a built-in encryption password that cannot be extracted by an attacker.
  • First described in 2018 a program at UCLA[1] developed a technique considered prior to that to be impossible. An algorithm that could serve as the basis for nearly any imaginable type of cryptographic protocol.


  • The ability of a computer program to hide its internal operations for view has be a goal, and a claim of many obfuscation methods for decades.
  • As soon as an obfuscation program was release, it as broken. Often within days of its release.
  • In 2001 the strongest form of obfuscation was proven to be impossible.[2]


The soluiont[3] works only if some of the current assumptions continue to hold. The most serious challenge to these assumptions is from the Quantum Computing Threat.
