A Simulation Study of Confidentiality Modeling in a Secured Supply Chain Network

In a supply chain network, suppliers normally offer price and service quotes for bidding while the purchasing company usually needs to evaluate suppliers before making buying decision. Due to competition, purchasing company doesnpsilat want suppliers to know anything about purchasing sensitive information except providing itemspsila retail prices and bidding notices. The confidentiality modeling has been proposed to use the Bell-LaPadula model and Markov Chain to dynamically monitor the state transitions in a secured supply chain network. This paper explains how to create a secured model in a simplified supply chain network. The properties of the model are examined based on two different protocols. We conclude by showing how to simulate the proposed model to solidify the effectiveness of the proposed model.
