SPKI/SDSI(Simple PKI/Simple Distributed Security Infrastructure) is improved security technologies of complicated characteristic of Hierarchical Architecture and weakness of access control. It is suitable that the technologies of SPKI/SDSI have characteristic of Horizontal structure for the closed circumstances. This paper will analysis complexity of using certificate between PKC and AC when the users of typical X.509 PKI structure move to another CA domain. To solve this problem, it will explain ways of authorizing user's certificate and authority faster when the user moves to another domain, it is easier to use the functions of SPKI/SDSI, Name Certificate and Authorization Certificate. Moreover, it will propose much more safer and effective Name Certificate issuance and Authorization Certificate's application by applying the managements of SPKI/SDSI's certificate based on the USIM cards.
