Secure Multiparty Computation (SMC) is the most widely recognized security issue. The issue is if expect there is no Trustworthy Third Party (TTP) accessible to accumulate the data sources, compute the function and allocate the outcomes to every different party who could misconduct at all. To handle this issue, a smart card-based security model, specifically TrustedPals has been proposed and built-in with the failure detector and consensus in asynchronous network configuration. However, the Asynchronous SMC (ASMC) model uses fixed-size of payloads in fixed time frames which may influence the tradeoff among safety measures and execution. So, Performance and Security Enhanced ASMC (PSEASMC) model was suggested that improves the tradeoff objective function by means of both execution and safety measures together to modify the tradeoff among safety measures and execution. On the other hand, the consensus was not resolved because of high storage and communication costs. Hence in this paper, Sublinear communication and Quantum protocol in PSEASMC model (SQPSEASMC) is proposed. This model is built up against reactive deception of a greater part of the parties for any layered Boolean and Arithmetic Circuits. In this model, a One-Time Truth-Table (OTTT) protocol is used to enable various parties to commonly assess N-party functionality by sharing between Alice and Bob. This secret sharing procedure is accomplished depend on the oblivious transmit of a bit-string message from Alice to Bob. The oblivious transmit based on bit-string protocol uses hash functions to verify whether Bob receives the message or not. Besides, the functionality can end on the probability that it receives an erroneously organized message. This protocol can reduce both capacity and communication complexities with expanded protection from malicious adversaries. Finally, the experimental results show that the proposed SQPSEASMC model achieves better performance than the PSEASMC to solve the consensus by minimizing storage and communication cost.
