With the rapid development and popularization of cloud computing, the security multiparty computation becomes a hot issue for the current research. This paper combs and analyzes the research of general security multiparty computation in cloud computing environment, and introduces the solution encryption schemes, including multi-key fully homomorphic encryption scheme based on Learning with errors and multi-key fully homomorphic attribute-based encryption scheme. This paper discusses the directions for future works in the end.

Enhancing the security of the dual party computation is considered as primitive to establish a secured multiparty computation in the geographically distributed networks. With the advent of variously distributed paradigms like Cloud computing, IoT and Fog computing, securing ubiquitous computation that involves multiparty collaboration is considered an open research area that attains the attention of the researchers to develop novel protocols. Addressing the problem of secured computation over the network this paper presents a novel and hybrid quantum protocol in with Quantum key distribution is integrated with 3DES to enhance the secure computations through a quantum channel within the cloud infrastructure. Simulation results of the proposed protocol show that it outperforms many security protocols developed based on quantum resources.

We propose a new notion of secure multiparty computation aided by a computationally-powerful but untrusted "cloud" server. In this notion that we call on-the-fly multiparty computation (MPC), the cloud can non-interactively perform arbitrary, dynamically chosen computations on data belonging to arbitrary sets of users chosen on-the-fly. All user's input data and intermediate results are protected from snooping by the cloud as well as other users. This extends the standard notion of fully homomorphic encryption (FHE), where users can only enlist the cloud's help in evaluating functions on their own encrypted data.
