Before the advent of FHE, Homomorphic Encryption (HE) was already advancing secure data computation. HE was designed to allow specific operations on encrypted data, ensuring that information remained protected even during processing. For example, with a basic HE system, one could perform operations like addition and multiplication directly on ciphertexts, which is encrypted data. The mathematical operations in HE are limited to either addition or multiplication but not both simultaneously. This means, if you encrypt two numbers a and b to get Enc(a) and Enc(b), you can perform operations such as:
