摘 要：隨著無線通信技術在智能電網中的廣泛應用，保證無線終端接入智能電網過程中的安全就顯得非常重要。本文提出一種面向智能電網的無線終端接入可信網絡體系結構，給出了其工作流程，并對此體系結構進行分析。分析結果表明，此模型通過增加終端對接入點的身份認證，防止了因接入點偽造而對無線終端造成危害，并將可信接入進一步擴展到了可信網絡，提出多級可信網絡的概念，使不同可信程度的設備可以擁有相應的訪問權限，使網絡資源得到最大程度的應用。
關鍵詞：智能電網；可信接入；可信網絡；無線終端

Abstract: With wide application of the wireless communication technology in smart grid, to ensure the safety when wireless terminal accessing the smart grid is very important. The paper presents
architecture of wireless terminal accessing
trusted network oriented smart grid, then gives the work flow and analysis of this architecture. The results show that by increasing authentication of terminal to access point, the model prevents damage to wireless terminal because of access point forged. The model also further extends trusted connection to trusted network and then presents multi-level trusted network which makes different credibility devices have the appropriate access rights and makes network resources have maximum degree of application.
Keywords: Smart Grid, Trusted connection, Trusted Network, Wireless Terminal
