What is Fully Homomorphic Encryption? Fully Homomorphic Encryption (FHE) is a cryptographic technique that allows arbitrary computation on encrypted data. This means you can take an encrypted input, apply a function to it, and produce an encrypted output that, when decrypted, matches the result of the function applied to the original plaintext. For example: Let E() be an encryption function and f() a function like addition or multiplication. Then, f(E(a), E(b)) = E(f(a, b)) FHE has been known in theory for decades but only recently became practical, thanks to advances in algorithms and performance optimizations. Zama has contributed to this progress by building open-source FHE libraries like Concrete, written in Rust, and optimized for both CPUs and GPUs.
