In the situation, this paper brought up the risk analysis and evaluation method on the basis of intelligent control and network communication technology for Network Communication System. The risk analysis and evaluation of Network Communication System firstly discussed the character of network communication and its risk. At the following we estimate a risk evaluation model according the distribution of the systems risk by time and space. Otherwise, we combined Fuzzy Comprehensive Evaluation with Analytic Hierarchy Process, and set up the multi-grade fuzzy comprehensive evaluation model for Network Communication System.

该方案主要通过讨论网络通信系统及其风险的特性，根据风险的时间和空间分布规律，以"风险"为整个网络通信系统安全模型的评估和分析对象，确立网络通信系统风险分布的量化评估模型，同时，就不同区域和不同时段的风险通过引入层次分析的一般方法来确定它们的权重系数，最后，通过模糊综合评判法则对系统中模糊不确定性因素进行数学化的抽象，建立一个反映其本质特征和动态过程的理想化的数学评估模型。

This situation, especially for circuital resource administration, has brought about big challenge. We need to build a set of management system to satisfy the need of communication resource management, which is high-effect.

It with wired compares mainly has the cost to be low, carries conveniently, omits the wired wiring the worry; Specially is suitable to grasping the equipment the correspondence, the battery power supply equipment, the vehicles monitoring, the remote control, the telemetering, the small wireless network, wireless copies the table, the system, the plot messenger call, the industry data acquisition system, the wireless label, the status recognition, must contacts the RF smart card, the small wireless data terminal, the safe fire protection is systematic, wireless domain and so on in external guidance system, biological signal gathering, hydrometeorology monitoring, robot control, digital audio frequency, numeral image transmission the low power loss, the microminiaturization is the current wireless correspondence product then takes along the product in particular the urgent need and the key question.

它与有线相比主要有成本低，携带方便，省去有线布线的烦恼；特别适用于手持设备的通信、电池供电设备、车辆监控、遥控、遥测、小型无线网络、无线抄表、门禁系统、小区传呼、工业数据采集系统、无线标签、身份识别、非接触RF智能卡、小型无线数据终端、安全防火系统、无线遥控系统、生物信号采集、水文气象监控、机器人控制、数字音频、数字图像传输等领域中。低功耗、微型化是当前无线通信产品尤其是便携产品的迫切要求和关键问题。无线通信的另一个关键问题是数据传输的可靠性，这取决于诸多因素，如频率选择、同频干扰、传输距离、天线选择等，这些在设计无线通信系统时都要认真考虑和比较。

The results show that DFH is not a LPI communication manner, and its security relies on the transition function.

分析结果表明：相关跳频通信并不是一种杭截获的无线通信方式，其通信安全是建立在转移函数机制上的。

It analyzed the remote communication means between client and server, the function of data marshal and unmarshal and the data security while communicating.

分析了远程通信中涉及的数据处理功能，包括数据的编码解码、数据的安全以及通信时的通信负载处理。

With the increasingly development of Network Technology, the data must be enciphered to protect from being intercepted or modified. So, the security of Computer Data Communication became a focus of our society, which leads to the development of encryption and deciphering technique of Computer Data Communication Security.

随着网络技术的不断发展，为了保护数据在传递过程中不被别人窃听或修改，我们必须对数据进行加密，从而计算机数据通信的安全问题也就成为当今网络社会的焦点，也自然导致了加密、解密等一系列关于计算机数据通信安全技术的产生和发展。

Based on an entangled pair of qubit, it allows asymptotically secure key distribution and quasi-secure direct communication. Its absolute security has been proved.

基于量子纠缠特性，乒乓协议允许绝对安全地进行明文直接通信和渐进地进行密钥安全分发，是一种绝对安全的即时通信协议。

TCP is a connection-oriented protocol, and to provide users with reliable, full-duplex stream of bytes, is confirmed, Flow control, multiplexers and synchronization function to better information security protection applies to data transmission, It can solve life, commercial, military and many other fields in network communications security issues.

TCP是一种面向连接的通信协议，为用户提供可靠的、全双工的字节流服务，具有确认、流控制、多路复用和同步功能，对信息安全有较好的保护，适用于数据传输，它可以解决生活、商业、军事等多个领域的网络通信安全问题。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
