留学生assignment代写精选范文：“Information and Communication Security Technology”，这篇论文讨论了信息通讯安全技术。如今智能手机的普及，使得信息通讯安全技术越来越被重视了。当用户的手机连接上网络时，很有可能手机里的信息就会被窃取，所以我们非常需要加强信息安全技术。要做到这些，就必须要加强网络安全管理，还有让手机拥有一个安全的工作环境。

Information and Communications Security is an issue of concern to everyone, especially after the advent of smart phones, the mobile phone consumer market share in constant growth, but the mobile phone network needs, people's means of payment is processed through the network, when network traffic unsafe, the user of all kinds of information will be intercepted copy, which measures if the property contains a password or ID card number, etc., will be a threat to the user's property. Therefore, development of communication technology is a double-edged sword, on the one hand it provides a convenient mankind, on the other hand adding more challenge for communications security maintenance. Discuss this article on security issues ICT, as well as to explore more detailed vulnerabilities for communications equipment.

Whether smartphone or PC, it needs to connect to the network is to make exchange of information, and both use the same network, but the network connection information there may be stolen lines, but these can only communications equipment added great convenience to our lives, so in order to more safely use only equipment, it is necessary to strengthen information security technology.

Of communication technology has developed rapidly, and now has come to a completely inseparable from the realm of communications equipment, according to statistics, China's smartphone sales on million, with communications the rapid development of network equipment up of many public places are equipped with free communication network, but the security of these networks should not have to protect, vulnerable to viruses of the network, the network may contain rogue software, so you constantly download software is not used, while the use of other means of intercepting them important information to analyze the bank card password, serve the purpose of illegal transactions. And because our host device using mostly pirated operating system, itself, security is low, so more vulnerable to viruses.

Because the network has a virtual and concealment, the police hunt for cybercriminals time, because of the traces of the invasion of bad judgment, so little useful information left to police, criminals more difficult, so exacerbated the network of criminals the rampant. So the network communication security is facing a difficult regulatory issues, which is the core of these problems is the secure communication network is low, you want to protect the security of communications necessary to establish a strict firewall security and communications technology standards.

From a macro point of view, secure communication technology can affect the stability and economic development of society, if there is no secure communication technologies that China's social development will face huge obstacles, cannot achieve real-time intelligence and some of the work, restricted the efficiency of economic development. From the microscopic point of view, communication security involves not only personal property issues, personal privacy will also be a greater impact, harassing phone calls, text messages and other emerging fraud in today's society, so they need a secure communications network management system, to defend the individual's right to privacy and personal property.

The hardware security issues 2.1 communications equipment of information technology has been able to rapid development, relying on the popularity of communications equipment to a certain extent, the rapid development of PC and smart phones to drive the development of information technology, but the information development of security technology has been relatively slow, especially now that communications equipment continues to develop small, the consequences of the information is stored simplification, although on the one hand to speed up the data read and write speeds, facilitate people's daily use but after a lot of storage device data is deleted, the file is actually not really been deleted, but is marked as the area can be covered, so you can very easily recover the data, and therefore the security of data communications equipment is an important the problem should be resolved as soon as possible this deficiency, but this requires the communication equipment update, the previous equipment was difficult to achieve feature protects data from being restored.

Communications equipment software system is an important factor affecting communication device information and communications security, in order to facilitate the subsequent management of the communications device software, in the beginning the development of the software, technical staff specially set up a secure channel. However, there is a safe passage, although there is a reasonable place, but also became the drawbacks of communications equipment is located. Many computer hackers or viruses are invading your computer through this channel and steal information, security of information and communication equipment communication thus been greatly threatened. Some software takes into account this, and given the repair function of the software, either automatically fix or repair manual can to some extent enhance the security of the communication device operating environment, but updates and information technology development speed is very quickly as possible, once the updating of information technology, it will make the old technology obsolete.

Advent of the Internet is linked with an infinite number of small-scale local area network, and effective collection of different network structures and data transmission path for each LAN. Based on this, TCP protocol was born. Proposed TCP protocol enables transmission between different network architecture and data communication with a common language, but this proposed protocol for all user groups, did not set a certain usage rights, so its safety is still being questioned.

For secure communications, the most direct way is for user authentication and identification, before the user-related information, the information is encrypted and set permissions, users only get to use the information the right to access information data, the government should introduce appropriate policies to constrain permissions. Insider set in the communication device identification system, the user only correct answer to the question of communications equipment, in order to prove their identity, the right to use communications equipment further information. As a result, some hackers, intruders information will not be like it used to be easy to steal information, and reduces the possibility of information leakage, so that the creation of user authentication and identification system is science-based, is a hundred Lee rather than harmful.

To be taken literally, malicious intrusion timely detection technology refers to the communication device when subjected to external intrusion suffered a virus, it can rely on its own to prevent the system to be accurate forecasting and effective solution. The structure and the technical properties of their own communication equipment requirements made higher, the transmission system node is a permanent position detecting device, the aim is to ensure real-time detection, accuracy and effectiveness.

To achieve information communication is decided rational allocation information and uplink transmission resources and the like by the coordinated control between the network-internal protocol. Thus, the destruction of its internal protocol is equivalent to destroying the integrity of the entire communications network running, again mainly for the simultaneous transmission of data transmission protocol of the original intercepted modify or correct information before the data of the identity of legitimate users Wait. No matter what kind of attack on the internal network protocols have seriously hampered the transmission of scientific data and information on people's production and life has caused tremendous threat. Internal Protocol network operation mode technique is constructed by the information transmission process reliability identification and verification, in order to achieve supervision for recombinant agreement to ensure the accuracy of the user information acquired, to optimize the operating environment information, from the more guarantee the security of information communication to a large extent.

Communications technology security is an issue we are concerned, so depending on the nature of the problem will be divided into two aspects, one is prone to the appropriate network problem, another problem appeared on the device. So when the two-pronged approach to improve the communication system security, on the one hand to strengthen the management of network security, anti-virus and firewall management increase in public network, update the device software on the other hand, the device is in a safer working environment, reducing the data to be restored possibilities, while enhancing network security protocol, to build a secure network protocol mode of operation.
