New application of reliable agreement: underlying an unsecured business environment

ABSTRACT

Due to the enterprise internationalization nowadays, each sub-company of the enterprise is located in different place. Under such circumstances, each sub-company must better itself with greater power and ability through coordination. Unfortunately, malicious hacker possibly fakes the communications between the sub-companies. The messages from sub-company might be changed in an unsecured environment. Thus, this paper proposes the Two-Phase Agreement (TPA) protocol to make easy the sub-companies' communication with the main-company or decision-making in company conference.
