An FHE compiler for C++Project mention: What are the current hot topics in type theory and static analysis? | /r/ProgrammingLanguages | 2023-05-08
Secure computing. This includes Fully Homomorphic Encryption AKA FHE, of which there is a language/compiler which just got released and Google's older FHE compiler. FHE is probably more "compiler" than "type system", e.g. Google's compiler works on C++. Also Security Type Systems which include Oblivious data structures and Oblivious ADTs.
Microsoft SEAL is an easy-to-use and powerful homomorphic encryption library. (by microsoft)
HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.Project mention: The Rise of Fully Homomorphic Encryption | news.ycombinator.com | 2022-09-29
For clarity, let's assume the hospital stores its records in plaintext. For the pharma company, the hospital encrypts the patient records with a secret key. Now they let the pharma company run their homomorphic algorithm and send the values back. Only problem is the pharma company can not read those results without having access to the key. FHE is completely redundant in this use case - the hospital could have simply run the pharma company's SQL and audited the code and outputs.
What is FHE actually good for then? Let's imagine you are a top secret agent and you get instructions to fly to Bulgaria as a part of your mission. You have other hostile agents constantly monitoring you, trying to understand your next move. But there's a problem - to buy a plane ticket to Bulgaria you need to know the name of it's capital city. You can't just type it to Google, because these other agents have infiltrated the Google servers and see what you search (assume once you actually know the name of the capital, you somehow buy the actual ticket without "them" knowing..)
Lukcily though, CloudCorp offers a public homomorphic query service for all world capitals. This service allows you to send a query for the capital of any country over an intercepted connection, and get back the result. Even if the hostile agents had infiltrated CloudCorp and were monitoring all your comms, they would not be able know which country's capital you just queried.
How such service would be implemented is explained in good detail in this tutorial: https://github.com/homenc/HElib/tree/master/examples/BGV_cou...
P.S. The capital of Bulgaria is Sofia.

Cryptographic filesystem for the cloudProject mention: How do I Password-Protect a single folder? | /r/archlinux | 2023-07-01
you have a couple options. if you’re using ext4, fscrypt might be your best bet. if not, a FUSE-based encryption option is probably your only option. ecryptfs, gocryptfs and encfs are good, but i personally prefer cryfs. it doesn’t have an archwiki page, but can be installed from the repos and instructions for use can be found on its webpage
IBM Fully Homomorphic Encryption Toolkit For Linux. This toolkit is a Linux based Docker container that demonstrates computing on encrypted data without decrypting it! The toolkit ships with two demos including a fully encrypted Machine Learning inference with a Neural Network and a Privacy-Preserving key-value search.Project mention: IBM Fully Homomorphic Encryption (HELayers) SDK for Linux | /r/CKsTechNews | 2023-02-14

There is concrete for homomorphic encryption, but that is not really a transport/compiler (yet).
Groestlcoin Core integration/staging tree
An advanced SAT solverProject mention: The Silent (R)evolution of SAT | news.ycombinator.com | 2023-05-26
It shares short conflict clauses between parallel solvers and achieves superlinear speedup in some cases, e.g., 4 parallel solvers solve faster than one forth of the single solver soolution time.
Short conflict clauses are rare so there is little communication between solvers required.
Author's goal to have solver that is good in computing range from single CPU up to cluster. Judging from CryptoMiniSAT successes, he has mostly reached the goal.
