Multiparty cloud computation can deal with the problem that the traditional homomorphic encryption can't operation on the ciphertexts generated by different users, and the final result is computed by cloud server. The trivial multiparty cloud computation doesn't take the access control to the final result into consideration. In reality, we perhaps do not want all parties to gain the result. In this paper we construct a predicate encryption with multiplicative homomorphic property for the class of inner-product predicates. The scheme can also support multiparty cloud computation. By use of predicate encryption, we can realize the fine-grained access control. At last, we prove that our scheme is secure under IND-AH-CPA.
