This is the presentation in a course named ECT , the paper is about technique like AAA ,RADIUS ,smart card ,jave card

1. Smart Card Based Protocol for Secure and Controlled Access Of Mobile Host in IPv6 Compatible Foreign Network 954203020 郭啟揚 954203039 鄭志瑋 954203057 蔡繼正

7. Smart Card(4/4)

11. RADIUS(1/2)

13. Diameter(1/4)

18. IP Source Address Filtering User identity IP Share key Share key

20. IPsec(3/5)

21. IPsec(4/5)

25. User registration protocol(3/4) LSA IPsec TSK TSK TSK

26. Local challenge VN_ID Care of address AUTH=HMAC-MD5(LC,user_id,VN_ID,SAmh) User Name AVP:user_id Extract LC , user_id , AUTH,VN_ID, MH_Ipaddr EAP AVP:AUTH Care of IP:MH_Ipaddr AAA Registration Request Challenge AVP:LC AUTH==HMAC-MD5(LC,user_id,VN_ID,SAmh ) HC,AUTHNET,Randtsk AUTHNET=HMAC-MD5(HC,user_id,VN_ID,SAmh) TSK=3DES(Randtsk,SAmh) ARA (Randtsk,HC,TSK,VN_ID,user_id,Authnet) EAP format AUTH=HMAC-MD5(HC,user_id,VN_ID,SAmh) AUTH==AUTHNET EAP format

27. Implementation detail Extensible Authentication Protocol AAA Registration Request

28. Comment(1/2) 3 6+3=9 訊息數 其他 技術 本名 縮寫 Mobile Authentication Protocol Internet key Exchange IPsec +IPv6+ Smart card PKI+IKE Temporary share key Two phase MAP IKE

29. Comment(2/2) 低 高 成本 不易 容易 key 竊取 易 難 建置 key 定時更新 Key 不能失去 Key 安全性 本名 縮寫 Mobile Authentication Protocol Public key infrastructure 高 低 MAP PKI

30. 所以 MAP 將會是未來的趨勢 你認為呢？ Thank you for attention Q&A
