In this paper, the concept of network security and security structures of OSI and Internet is introduced, and various threats confronting the computer network are also discussed. Several kinds of network information security technologies, including firewall technology, virtual private network, intrusion detection system, data encryption technology, identity authentication and security protocol etc. are also examined. The security of internal network is the biggest problem in the construction of each network. The solution to this problem lies in setting up a firewall. The theory of a firewall and the approach to its actualization is studied. Intrusion detection system, an important part of the computer network security system, has gained extensive attention. IDS monitors the computer and network traffic for intrusion and suspicious activities. It not only detects the intrusion from the extranet hacker, but also the intranet users. The emergence of virtual private network paves the way for realizing secure connection of LAN quickly and at a relatively low cost. The concept, function, key techniques, including the tunnel technology, and the ways to realize VPN are expounded in this paper. Also introduced is the data encrypt network technology, which is called the soul of computer network security, such as digital digest, digital signature, digital certificate, digital encrypt arithmetic and so on. At the same time, the principle and the process of implementing network security by digital certificate and digital signature, the basic principle and characters of security protocols, and finally, three of the security protocols, concerning the security problems in network, IPsec, SLL and SET are analyzed in detail Computer network system should be a system of dynamic defence, both dynamic and static, passive as well as active, and even offensive, combined with management and technology.

本文系统地介绍了网络安全的概念、OSI及Internet的安全体系结构，并讨论了计算机网络面临的各种安全威胁；内部网络的安全问题是每个建网单位面临的最大问题，可以认为防火墙技术是解决网络安全的一个主要手段，本文研究了防火墙的原理及其实现手段；作为一种主动的防御措施，入侵检测系统作为网络系统安全的重要组成部分，得到了广泛的重视，TDS对计算机和网络资源上的恶意使用行为进行识别和响应，不仅检测来自外部的入侵行为，也监督内部用户的未授权活动；虚拟专用网技术的出现，为实现网络间的连接提供了快速安全但又相对便宜的手段，本文较深入的探讨了实现VPN的隧道技术，并对VPN的概念、功能、实现途径、基本构成、关键技术及发展前景等问题进行了全面论述；数据加密技术是网络安全核心技术之一，本文从数据加密算法、数字摘要、数字签名及数字证书等几方面简要介绍了数据加密技术，并分析用数字证书和数字签名实现网络安全的原理和过程；对安全协议的基本原理、主要特点进行了较为深入的研究，并就网络的安全性问题剖析了三种安全协议：IPsec协议、SLL协议和SET协议。

Through the comparative analysis between the functions of the government"s'role in establishing a social security system in Britain, the US, Germany, Japan and other countries and Chinese government"s absence from their duties in establishing rural social security, we know, under the socialist market economic conditions, the government should bear the basic responsibilities in establishing the rural social security system, just to build a basic framework of the rural social security system adapted to the level of economic development, to establish a rural social security management system, to bear national financial responsibility in establishing the rural social security and promote mufti—dimensionally raising funds, to establish a rural social security monitoring mechanism, to establish a rural social security law system, to create external environment of the rural social security system, and so on.

在英、美、德、日等国构建社会保障制度中政府职能的角色定位与我国农村社会保障政府缺位的比较分析中，我们得出，在社会主义市场经济条件下，构建农村社会保障体系中政府应承担的基本职责，即构建和经济发展水平相适应的农村社会保障制度的基本框架，建立健全农村社会保障管理体制，承担国家对农村社会保障的财政责任并推动多渠道筹集资金，建立健全农村社会保障的监管机制，推动农村社会保障的法律体系建设，创造农村社会保障制度建设的外部环境等等。在当前的条件下，我国政府应着手采取现实可行的具体措施来履行其职能、推进我国农村社会保障体系的建设。

But our country's present social security system actually has the hindrance function to the occupation mobility, the main performances are as follows: Two units social security system, the unequal tax revenue system in the social security, social security singleness in view of the impoverished social class, hardly carried and transferred characteristics of social security system , ignoring benefits protection of mobile staffs, lack of social security legislation , slow development of service system of social security ,lack of policies and measures on promoting regional motilities insocial security system.

但是，我国现行的社会保障制度却对职业流动有着一定的阻碍作用，主要表现为：二元的社会保障体系的存在，社会保障体系的便携性、可转移性较差，忽视流动职工的利益保护，社会保障立法的缺失，社会保障服务体系发展缓慢，社会保障中税收体系的不平等，针对贫困阶层的社会保障单一，社会保障体系缺少促进区域流动的政策与措施等方面。

First, the rural social security system should be developed in accordance with the national conditions, including economic and social development status quo, people's views and security traditions. Next, the thesis puts forward the guiding thought and general principles for the establishment of the system based on the national conditions, and clearly sets forth the idea of establishing the transitional rural social security system. Then, the thesis makes explanation and analysis respectively on the existing security types, hoping to find the proper components of the rural social security system that is suited to the conditions of the country. At last, the thesis puts forward the objective mode and transitional mode of the establishment of the system at the macro level. The objective mode is the development direction of the transitional mode, and the transitional mode is a necessary stage of the objective mode. Only when establishing the vigorous transitional mode that is suited to the national conditions and achieving development, can the objective mode be possibly realized in the self-evolution of the transitional mode.

首先，我国农村社会保障制度建设应当立足于我国的基本国情，包括经济社会发展现状、人们的观念、保障传统等方面；其次，在基本国情的基础上提出了建立我国农村社会保障制度的指导思想和一般原则，明确提出了建立过渡型农村社会保障制度的构想；而后，本文对农村社会保障现存的几种保障方式一一做出了说明和分析，以期为构建适合我国国情的农村社会保障制度模式找到合适的构成要素；最后，本文从较为宏观的层次提出了我国农村社会保障制度建设的目标模式和过渡模式，目标模式是过渡模式的发展方向，而过渡模式是目标模式建设的必经阶段，只有在建立适合国情具有活力的过渡模式并取得发展的基础上，目标模式才有可能在过渡模式本身的自我升级过程中逐步实现。

In order to analyze the reason for a flawed Iraqi identity, this article delaminates the internal identity of Iraq to two levels——national and sub-national, further distinguishes familial identity, religional identity and ethnic identity on the sub-national level, and studies the relations between national and sub-national identities with looking back at the momentous events in Iraqi history, consequently finds the different influences that various of sub-national identities react on the formation of Iraqi national identity and how the discriminative internal policy intensified sub-national identities, and then builds a theoretical framework with two dimensions from upwards and downwards to explain the reason for unshaped Iraqi national identity.

为了分析伊拉克国家认同没有形成的原因，文章将伊拉克内部认同在国家和次国家两个层次上进行划分，并进一步区分了次国家认同中的家族部落、宗教派系、族群这三个认同类型，然后以国家认同和次国家认同的关系为切入点，研究了伊拉克历史上的几个重大事件，发现了各次国家认同对国家认同的形成具有不同程度的影响，其中族群认同对国家认同形成的破坏作用最大；与此同时，伊拉克前政府歧视性的内部政策强化了各次国家认同，是造成伊拉克国家认同没有形成的另一个原因，从而从上、下两个维度解释伊拉克国家认同未形成原因的理论架构。

This thesis deeply researches the J2EE security strategy on the application tier of enterprise system. The security strategy predigests the information security model and meets the security requirements expediently. But there are some disadvantages when the security requirements become more complex. The expositive security on the Web-Tier can not offer more information for authentication; there is no authentication for EJB-Tier to use, make the EJB-Tier depend on the Web-Tier; J2EE uses database or application server to manage the role information. Use database to manage the role information will increase the complex of enterprise application, and the way of application server will reduce the ability of migrate other J2EE platform. To solve these problems, the thesis designs an improved security strategy model.

本文从企业级系统应用层安全的角度出发，深入研究J2EE多层体系结构的安全策略模型。J2EE提供的安全策略简化了系统的信息安全模型，能够很方便地满足基于J2EE的分布式应用系统的安全需求，但是在面对更加复杂的安全需求时，J2EE安全策略在验证授权和角色管理中还存在不足之处：其在Web层的声明式验证机制无法为用户提供更多验证信息，可扩展性较差；在EJB层缺少业务逻辑层可供采用的验证机制，而是借助于Web层的验证机制，其耦合程度较高有悖于业务逻辑分离于表现逻辑的原则；在角色管理方面，J2EE采用数据库或者应用服务器来管理角色信息，其中，数据库管理角色的方式增加了应用开发的复杂度，应用服务器管理角色降低了系统的可移植性，两者都具有片面性。

Currently it still exists many problems in Social Security System, such as incomplete legal institutions of social security, incapacious scope of security coverage, insufficient social security funds, disordered department functions and third sector's laggard development in social security system even though we have achieved obvious fruits in the reform of Social Security System, relatively increased the scale and level of social security too.
