After the briefly present the origin and features of internet protocol version 6 ( ipv6 ), the paper detailedly introduced the conception, characters, security technologies of vpn, and main tunnel protocols used to implement and deploy vpns. after analyzing and comparing these technologies of realizing vpns, we choosed ipsec. then, the paper analyzed in the ipsec structure, function, work mode, and its components such as authentication header ( ah ), encapsulating security payload ( esp ), internet key exchange ( ike ), encryption and authentication algorithms, security association, security policy, and how they cooperate with each other in order to secure ip packages
在簡要介紹ipv6協議的由來和優點之後，詳細闡述了虛擬專用網的概念、特點、安全技術及實現的關鍵隧道協議，通過對實現技術的分析比較，選用了安全性強大的ipsec隧道技術，接著深入研究了ipv6安全協議ipsec的體系結構、操作模式，詳細論述了ipsec協議簇的各個組成部分，如認證報頭ah協議、封裝安全載荷esp協議、密鑰管理ike協議、加密認證演算法、安全聯盟和安全策略等，以及這些組件之間如何協作，來共同實現對網路層ip數據包的安全保護。 -

This paper described the design and realization of a command and communication system database in the environment of vfp. it briefly introduced the mostly function, the system frame, the constitute & the information flow ; it introduced the key techniques used in the database design, such as user interface designing technique, application system toolbar designing technique, multi - media technique, data exchange technique, security and maintaining secrecy technique, etc. moreover it do more analysis, research & prospect for these technique & the developing way of the system
本篇描述了vfp環境下某指揮通信系統數據庫的設計和實現；簡要介紹了該數據庫系統的主要功能、體系結構、組成和信息流程；介紹了數據庫設計中的用戶界面設計技術、應用系統工具欄設計技術、多媒體技術、數據交換技術、安全保密措施等技術，並對這些技術以及系統的發展方向進行了進一步的分析、研究和展望。 -
A secure authentication and key exchange protocol is designed in this thesis, which could prevent man - in - the - middle attack, increasing the reliability of authentication and security of key exchange. the data encryption module is implemented by openssl including symmetry key algorithm, public key algorithm, hash function. the system ’ s function is tested finally, the data transmission rate using different encryption algorithm
研究並設計了一套基於數字證書和數字簽名技術的身份認證協議和密鑰交換協議，能夠有效地防止中間人的竊取和篡改，提高了身份認證的可靠性和密鑰交換的安全性;利用openssl標準庫函數實現系統的數據加密模塊，實現對稱加密、非對稱加密以及信息摘要的常用演算法。 -
First, the author makes some obvious improvements on algorithm implementation for protocol design, which has distinct advantages over the original fair document exchange protocol with aspects of security and applicability. secondly, the integrated protocol implementation is accomplished in detail based on java 2 platform ( take the document exchange protocol as an example ). thirdly, during the process of the protocol implementation, the paper also puts the emphases on considering the multiple achievements of message queues and relative comparison on working function, which provide the secure and stable mechanisms for the protocol applications
本文的貢獻有以下三個方面，首先，在初始的文件交換協議的基礎上，在安全性及適用性方面對該協議的演算法提出了較大幅度的改進和完善，提出了改進后的文件交換協議版本v1和v2 ；其次，本文作者提供了基於java2平臺上的具體完整的協議實現；然後，在協議實現的過程中，本文還重點考慮了消息隊列的多種實現方式及相關性能比較，為協議的應用提供安全穩定的實現機制。
