Abstract—Cloud computing provides solutions as a service to meet customers’ needs such as massive data storage and a lot of computing resources to process customer data efficiently. To fully utilize such services, data need to be outsourced to Cloud Service Providers (CSPs). However, outsourcing precious data to the CSPs could lead to a disaster. Thus, the data need to be protected by means of encryption techniques. Primitive encryption techniques are ineffective to be used as such techniques required decryption process. To overcome such a problem, a fully homomorphic encryption (FHE) scheme is needed as the scheme enables encrypted data to be processed in an encrypted form. There are a number of existing FHE schemes have been proposed and improved upon, but efficiency is still a big obstacle for their implementation. Thus, in this paper, a new fully homomorphic encryption scheme based on finite fields that supports an n-multilinear map is proposed. The scheme should support the n-multilinear map so as to allow for arbitrary multiplications on encrypted data. Moreover, a new protocol that enables three or more parties to communicate with one another to process data in an encrypted form is proposed in this paper.
