Several number theoretic and algebraic homomorphic encryption schemes were proposed in the literature, which have been remained theoretical due to their high computational complexities. Coding theory is believed to be a promising alternative for the construction of homomorphic encryption schemes. A few of such schemes exist, but, they support limited operations of additions and multiplications over the ciphertexts. Based on a special class of linear codes called Reed-Muller codes, in this paper, a new symmetric key Fully Homomrphic Encryption (FHE) scheme is proposed, which employs a novel method of ciphertext post processing to achieve unlimited homomorphic multiplications. The security of the proposition is analysed with respect to all the known attacks.
