HElib
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.
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.

Project mention: Ask HN: What are some of the most elegant codebases in your favorite language? | news.ycombinator.com | 2023-06-17
-
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

fhe-toolkit-linux
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: Is there a Rust equivalent for Fully Homomorphic Encryption? | /r/rust | 2023-02-15
There is concrete for homomorphic encryption, but that is not really a transport/compiler (yet).

InfluxDB
Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

There's cppcryptfs & securefs as Cryptomator alternatives too. SiriKali is an option for a GUI that works nicely with them.

GpgFrontend
A free, open-source, robust yet user-friendly, compact and cross-platform tool for OpenPGP encryption. It stands out as an exceptional GUI frontend for the modern GnuPG (gpg).
Project mention: Mastodon's Privacy: Who actually holds your data in Mastodon | /r/privacy | 2022-11-29If there is enough text space for OpenPGP payloads (they can get quite large), you could secure your privacy by using this tool https://github.com/saturneric/GpgFrontend and copy and paste that into Mastodon chats.

Dynex
Dynex is a next-generation platform for neuromorphic computing based on a new flexible blockchain protocol. It consists of participating nodes that together constitute one enormous neuromorphic computing network. Consequently, the platform is capable of performing computations at unprecedented speeds and efficiency – even exceeding quantum computing. Everyone is welcome to participate, since the Dynex neuromorphic computing chip is capable of being simulated using almost any device, from regular

DistributedATS
DistributedATS is a FIX Protocol based multi matching engine exchange(CLOB) that integrates QuickFIX and LiquiBook over OpenDDS
Several open-source projects can give you a head start. QuickFIX https://github.com/quickfix/quickfix FIX is the ABC of electronic trading. FIX is not a low-latency protocol, but it covers all aspects of electronic trading, from authentication to market data to order entry to post-trade reporting. Every trading venue supports FIX, so you must be familiar with it. QuickFIX provides FIX Server and Client implementations for all versions used on the street and python wrappers for all components. LiquiBook https://github.com/enewhuis/liquibook LiquiBook is an example of a low-latency matching engine. This project should give you an idea of how exchange matches orders. Itch-order-book https://github.com/charles-cooper/itch-order-book Itch-order-book is an example of a low-latency code to process market data. This project is an example of how to process millions of order book changes per second. ITCH is a low-latency market data protocol used by NASDAQ DistirbutedATS https://github.com/mkipnis/DistributedATS DistirbutedATS integrates QuickFIX and LiquiBook to create a simple yet functional exchange. DistributedATS is my experimental project so let me know if you have any questions.
