Homomorphic Encryption for Pseudonymization – privacy enabled data-sharing

Fully Homomorphic Encryption (FHE) allows the calculation on encrypted data. Invented in 2009, it was traditionally too slow to be realistic for real use. With new innovations, it has now become possible to run in production.

This blogpost shows a practical application that uses AES encryption in FHE - yes, you are encrypting under encryption - to mask identifiers to enable datasharing.
