Understanding Fully Homomorphic Encryption (FHE) Fully Homomorphic Encryption (FHE) is an encryption method that allows computations to be performed on encrypted data without the need for decryption. This revolutionary approach ensures that data remains confidential throughout the computation process. In simpler terms, FHE enables arithmetic operations or even more complex calculations to be carried out on encrypted data, with the results remaining encrypted until decryption. This level of security is unprecedented and provides significant advantages in various applications. A Brief History of FHE The concept of FHE was first introduced in 1978. Despite the early recognition of its potential, it wasn’t until 2009 that the first practical FHE scheme was developed. Over the years, numerous researchers faced significant challenges in creating an efficient FHE algorithm. However, with advancements in technology and mathematical methods, and the relentless efforts of the cryptographic community
