Homomorphic encryption schemes based on coding theory and polynomials

arXiv:2509.13788v2 Announce Type: replace Abstract: Homomorphic encryption is a powerful cryptographic tool that enables secure computations on the private data. It evaluates any function for any operation securely on the encrypted data without knowing its corresponding plaintext. For original data $p$, $c$ denotes the ciphertext of the original plaintext $p$, i.e. $c = Encrypt_k(p)$.
