When I first learned about homomorphic encryption it gave me the idea of "cryptographic AI", as some sort of sci-fi writing prompt. Suppose compute is readily available to interstellar civilizations but actually designing a (super)intelligent AI is difficult. Then it could be economically feasible for cryptographic AI to exist. These are descriptions of AIs that run under homomorphic encryption, where the private key…
Curious if there's tooling to de/serialize the encryption context? The examples aren't very useful to demonstrate "real" homomorphic encryption in the sense that it takes in plaintext directly; encrypt and transforms; then decrypts - I'd love to see a snub that takes encrypted input (only) and returns ciphertext of the result - that can then be decrypted on a client node provided the correct key? Or is this supposed…
There seem to be built-in methods for serializing and deserializing crypto context as well as ciphertexts [0], so it shouldn't be too difficult to build a "complete" example that performs the actual computation in a different application. That said, with a duration of 7 seconds for a simple addition, it is still far from many practical applications, in my opinion. [0] https://github.com/openfheorg/openfhe-development…
> First, the subset of C++ supported by the compiler is rather small. As mentioned earlier, all data needs to have static sizes. This means, e.g., you can’t write a program that processes arbitrary images. Instead, you have to pick an upper bound on the image size, zero-pad the image appropriately before encrypting it, and then write the program to operate on that image size. In the same vein, the integer types you c…
sounds like you could have anonymous currency. heres our FHE bank. we both have accounts. the entire ledger is encrypted. i give you 5 dollars, i have no idea what your starting and ending balance, but i am still able to initiate a transaction that will deduct 5 from mine, and add 5 to yours, and verify i actually have 5 to send, and the entire thing will be done without exchange of information about balances with an…
What purpose would this serve? Just anonymity for the sake of anonymity, or something else?

Yeah I’ve always wondered if FHE would benefit from asic level acceleration, or at least FPGA
If you are going to do an asic (w/o data going to memory IO) then why not use regular encryption with codec on the SoC itself (like DRM content). that works just fine. IMO the main value here would be trust between unknown parties over untrusted medium.

I love/hate this. It's one of those ideas that's incredibly appealing to people who already have other ways of doing it, and incomprehensible to people who would actually benefit from it. Most things of that ilk get blown up because once it's peddled to the masses, consumers don't verify that it's actually run the way it's supposed to be run, and someone writes in a backdoor (FTX). Then it just takes a few hyped up c…
Interesting. I had given up on that idea. Not just for poker, but MMOs n stuff. Figured anything of importance had to run server-side.

Check out the Hyperion cantos by Dan Simmons.
That's funny, I started with Hyperion two weeks ago. I like it :)
