I have a problem which has several layers;

  • Provide a distributed computing plane where actors can voluntarily add and remove computing resources from, the actors are untrusted by default, and thus their resources too.
  • Actor A wants to run application 1 (a container) that gets scheduled on a computing resource provided by actor B, B is malicious to user A and wants to sniff on app 1, prevent this.
  • Execute a OCI (open container initiative) Container on an untrusted host in such a way that prevents unauthorized node-local admin access to resources or running state.
  • Execute a x86-64-compiled program in such a way which is hidden/shadowed to the executing resource (the CPU and memory) while being resistant to tampering.

The above problem can be shuffled around (encrypt program state/instructions and allow supervisor to access the underlying resource), but mostly it would push the problem around (the supervisor can be compromised by malicious hardware).

What I want to achieve is provide containerization resources in a zero-trust environment, by cryptographically/mathematically/logically making the program state uncompromisable to and beyond the level of the actual final decoded CPU instructions, I assume that anyone (with enough time) would be able to sniff and scrap together a complete saved and snapshotted state of the application, if they had complete access to the hardware, and/or create custom versions which highjack instruction flow.

I want to create a black box from off-the-shelf computer hardware, and/or standard instruction standards, which the actor only has to give compute resources to to make it run.

I want to be able to not trust the hardware it's running on, the CPU. Is this possible in any (practical) way?

No, nothing that is secure anyway.

Currently available systems are standard methods of making sure an app can't be run without a license. However these can be reverse engineered relatively easily.

Secure obfuscation is a topic of current research. So far it has not been implemented yet but mathematicians are working on it. One method is using cryptographic multilinear maps.
