2、明了非范式協(xié)議如何逐步向各級別范式轉(zhuǎn)換的過程,總結(jié)歸納了協(xié)議規(guī)范化的基本步驟。利用協(xié)議范式,不僅有助于判定安全協(xié)議抗攻擊的級別,還可以分析和改造已有協(xié)議,使其達(dá)到一定的范式級別,從而提高其抗攻擊能力。關(guān)鍵詞:安全協(xié)議;抗攻擊;時序模式;攻擊層次;狀態(tài)與信念綁定;協(xié)議范式西南交通大學(xué)博士研究生學(xué)位論文第m頁AbstractWiththepopularizationofInternctandthedevelopmentofvariousapplicationslikeelectronicbusinessonInternet
