由于電子商務廣泛采用公開密鑰技術，職能部門有必要對公鑰加以管理。本文簡要介紹了基于PKI的密鑰托管技術及密鑰托管代理的概念，分析了密鑰托管的步驟，以及政府部門在密鑰托管代理的幫助下強制訪問信息的過程。 關鍵詞：密鑰托管 證書授權認證 公開密鑰 公鑰基礎設施 托管證書 網絡的安全問題得到人們的日益重視。網絡面臨的威脅五花八門：內部竊密和破壞，截收，非法訪問，破壞信息的完整性，冒充，破壞系統的可用性，重演，抵賴等。于是公鑰基礎設施（Public Key Infrastructure，PKI）應運而生。PKI是電子商務和其它信息系統的安全基礎，用來建立不同實體間的"信任"關系。它的基礎是加密技術，核心是證書服務。用戶使用由證書授權認證中心（Certificate Authority，CA）簽發的數字證書，結合加密技術，可以保證通信內
