A modern service-oriented extensible security authentication model based on company

This paper proposes a modern service-oriented extensible authentication model base on company (EAMBCom), after researching some security authentication models commonly used in distributed environment. The advantages and disadvantages of strictly hierarchical authentication model (SHAM), and multiple-certificate-authority (multi-CA) model are analyzed. The EAMACom model can regard “company” as logical authentication unit, which can be extended easily and owns the ability of reducing burden of root certificate authority (RootCA). In addition, the EAMACom model can simplify the certification process on the premise of authentication security, so it actually can be used in modern service-oriented distributed file system for security.
