The discussion on the enumeration question of the integer solution for the indeterminate equation 關于不定方程整數解計數問題的討論
In this paper , we investigate some properties of positive integer solutions of indeterminate equations ( the equations is abbreviated ) , moreover , we describe the resects of all positive integer solutions on factor analysis solutions of indeterminate equations 摘要引入了不定方程正整數解的有關性質的引理和定理,并在此基礎上給出了求解該不定方程的所有正整數解的因數分析解法。
Integer solution of government networks security aiming at hidden trouble of network security is studied thoroughly in this paper , such as host computer of government network may be attacked by illegal in break , sensitivity data may be revealed or modified , information of intranet to internet may be wiretapped or tampered , etc . firstly , the security of government network , consisting of security analysis of risk , requirement , strategy and target of government are analyzed 本文針對電子政務系統網絡中的主機可能會受到非法入侵者的攻擊,網絡中的敏感數據有可能泄露或被修改,從內部網向公網傳送的信息可能被他人竊聽或篡改、系統工作效率可能受到嚴重影響等安全隱患,對電子政務系統網絡安全整體解決方案進行了深入研究。
Secondly , the integer solution of government network security , which is classified as physical security , access controlling , communication secret , data protection , security audition , virus protection , security backup and security management , etc are analyzed . lastly , an integer solution of a unit ’ s network security sichuan through the analysis of risk and acquirement as an applying instance are briefly designed in the paper . the integer solution of government network security , which is analyzed in the paper , is essentiality to the aspect of security , integrality , usability , controlling , auditing of network system , also can be used to help building e - government in other cities 首先對電子政務系統網絡的安全進行了分析,其中包括網絡的安全風險分析、安全需求分析、安全目標分析,以及電子政務的安全策略分析;然后,從物理安全、訪問控制、通信加密、數據保護、安全審計、病毒防護、安全備份和安全管理等方面對電子政務網絡安全解決方案進行了分類研究;最后,作為一個研究應用工程實例,通過對綿陽市電子政務信息網絡的風險分析及安全需求分析,對其網絡安全的整體解決方案進行了詳細設計。
