In this paper, we propose an efficient locking and unlocking method for sequential systems. The method is based on extracting and utilizing an inherent property of synchronicity directly from the original sequential system without modifying the system. We analyze the synchronicity property in the context of sequential locking and unlocking function. We address the advantages and limitations of proposed method. The feasibility of proposed method is also demonstrated.
