在行動隨意網路上無線節點彼此間的相互溝通是藉由公開的媒介來達成。由於缺乏固定的網路基礎建設或任何集中式管理機制以及每個節點的無線訊號傳輸範圍是有限的，任兩個節點之間的溝通常常必須通過其他的節點來達成。換句話說，每個節點必須執行繞徑以達成資料傳遞，並且必須為其他節點轉送控制與資料封包。
不幸的是，於行動隨意網路上的任何節點都有可能是惡意的節點，他們會藉著攻擊此網路進而得到某些效果。首先像是惡意的節點會經由流量分析的攻擊而得到網路上通訊方的資訊。此外惡意的節點還會發動主動式攻擊，例如路徑需求封包氾濫攻擊和路徑回覆封包氾濫攻擊去消耗網路上的頻寬和每個節點的資源。由此可知，如何於行動隨意網路上抵擋主動式與被動式攻擊是非常重要的。
因此，我們提出一個安全匿名路由協定，來提供身分的私密性性、位置的私密性和路徑的匿名性在行動隨意網路上。除此之外，我們的方法還能夠抵擋路徑需求封包氾濫攻擊、路徑回覆封包氾濫攻擊和流量分析攻擊。我們還會藉著匿名性和安全性的分析來說明我們的方法能夠提供上述兩種性質在行動隨意網路上。
我們使用NS-2網路模擬軟體來模擬實作我們的方法，並且藉著實驗結果證明我們的方法能夠有效的達成我們的目標。
