中文摘要 | 因為GSM網路業者間答訂的漫遊協議,所以即使我們到其他幅旅遊時仍然可以使用原本的手機門號,但是檢視現行GSM系統的鑑別機制,我們可以發存在MS與VLR間無法相互鑑別、增加HLR與VLR間傳遞鑑別資訊頻寬負擔及VLR額外儲存負擔等三項缺點,針對上述的現行GSM鑑別缺失,雖已有學皷提出相關研究的改進方法,但是圾僅限於決上述的部份問題或是需要改變現行GSM架構。本論文在不改變現行GSM系統架構下,將提出一個有效率且能夠同時解決上述三項缺點的GSM相互鑑別機制。 |
英文摘要 | Since many GSM network operators have roaming agreements with foreign operators, users can often continue to use their mobile phones when they travel to other countries. There are several drawbacks found in existing authentication protocols of GSM, such as the fact the VLR cannot be authenticated, unbalanced communication bandwidth consumption between VLR and HLR, and storage overhead in VLR. Recently, many authentication protocols have been proposed to solve those drawbacks of the existing GSM authentication protocols, but they cannot alleviate all drawbacks without altering the GSM architecture. In this paper, we propose a novel mutual authentication protocol to solve all of the above problems without changing the existing GSM architecture. |
