Chapter 1: Fundamentals (Journey with FHE) @zama 1 - Core Concepts To begin, it’s important to understand the difference between classical encryption and FHE. Traditional schemes like AES and RSA ensure that data is secure while being stored or transmitted. However, whenever computations are required, the data must first be decrypted, which introduces the risk of leakage. In contrast, FHE allows us to perform computations directly on encrypted data, and once decrypted, the result is exactly the same as if the computation had been performed on the raw data. This is the breakthrough that sets FHE apart from classical encryption. At the heart of this idea lies Homomorphic Encryption (HE) – a special type of encryption that preserves an algebraic structure between plaintexts and ciphertexts. In simple terms, an operation carried out on ciphertexts corresponds directly to the same operation on the original data after decryption #ZamaCreatorProgram HE ?
