电子信息安全技术研究
Electronic and Information Engineering is the information industry and the important foundation for one of the pillars. It circuits and systems, signal and information processing, microwave and electromagnetic field theory, to study various information, such as voice, text, images, radar, remote sensing and other information processing, exchange and wireless, cable, fiber optic cable and other transmission, Based on this study and development of electronic and information systems. Professional training with the electronic technology and information systems knowledge base, be engaged in all kinds of electronic equipment and information systems research, design, manufacture, application and development of high-level engineering talent. May engage in signal processing, transmission, switching and detection technology research and teaching work, electronic equipment and systems development, production and application, electronic technology, computer technology and the application and development of microwave technology, application and development.
电子信息工程是信息产业的重要基础和支柱之一。它以电路与系统、信号与信息处理、电磁场与微波等理论为基础，研究各种信息如语音、文字、图像、雷达、遥感信息等的处理、交换及无线、电缆、光缆等的传输，在此基础上研究和发展各种电子与信息系统。本专业培养具备电子技术和信息系统的基础知识，能从事各类电子设备和信息系统的研究、设计、制造、应用和开发的高等工程技术人才。可从事信号的处理、传输、交换及检测技术的研究与教学工作，电子设备与系统的研制、生产与应用，电子技术及计算机技术应用与开发，微波技术的研究、应用及开发工作。
The enterprise management information system in many business documents in circulation, there is the importance of documents, and some even related to the future development of enterprises, if the information is competition in general network transmission opponent or illegal eavesdropping, tampering or leak, forgery,
development, would be a serious threat to enterprises so, research the security of the electronic information technology small and medium-sized enterprise has important significance.
在企业的管理信息系统中有众多的企业文件在流转，其中肯定有重要性文件，有的甚至涉及到企业的发展前途，如果这些信息在通用过网络传送时被竞争对手或不法分子窃听、泄密、篡改或伪造，将会严重威胁企业的发展，所以，中小企业电子信息安全技术的研究具有重要意义。
In the era of network information, the process of enterprise information development, information has become the key to the success of the enterprise, also an important way to improve management level. The enterprise business activities now, basically use the electronic commerce form, operation, transportation and sales are all applied to information technology. Such as through the network to collect some information about the quality of raw materials, prices, production and other information to establish a materials information system, purchasing of raw materials has a significant role in the information system. Through the analysis of the data, can be obtained with the procurement proposal and strategies, achieve enterprise electronic information technology level. The survey, eighty-two percent of small and medium-sized enterprises of the site should also in the propaganda enterprise image, product and service information, this stage to collect customer information, and e-commerce transactions related to the application of less than 1/4, indicating that the enterprise has not been fully developed and the use of commercial information channels. The information age has come to small and medium-sized enterprises, enterprises should speed up the construction of informatization.
在这个网络信息时代，企业的信息化进程不断发展，信息成了企业成败的关键，也是管理水平提高的重要途径。如今企业的商务活动，基本上都采用电子商务的形式进行，企业的生产运作、运输和销售各个方面都运用到了信息化技术。如通过网络收集一些关于原材料的质量，价格，出产地等信息来建立一个原材料信息系统，这个信息系统对原材料的采购有
很大的作用。通过对数据的分析，可以得到跟多的采购建议和对策，实现企业电子信息化水准。有关调查显示，百分之八十二的中小企业对网站的应还处于宣传企业形象，发布产品和服务信息，收集客户资料这一阶段，而电子商务这样关系到交易的应用还不到四分之一，这说明企业还未充分开发和利用商业渠道信息。中小企业信息化时代已经到来，企业应该加快信息化的建设。
Encryption technology can make the data transmission more safety and integrity, encryption technology is divided into symmetric and asymmetric encryption two. The symmetric encryption usually by sequence cipher or group secret to achieve, including plain text, key, encryption and decryption algorithm and the five basic components. Asymmetric encryption and symmetric encryption is different, asymmetric encryption requires a public key and a private key of two keys, a public key and a private key must match, using public key encryption, only the corresponding private key can decrypt. Using the private key encryption, and only use the corresponding public key can decrypt.
加密技术能够使数据的传送更为安全和完整，加密技术分为对称和非对称加密两种。其中对称加密通常通过序列密码或者分组机密来实现，包括明文、密钥、加密算法以及解密算法等五个基本组成成分。非对称加密与对称加密有所不同，非对称加密需要公开密钥和私有密钥两个密钥，公开密钥和私有密钥必须配对使用，用公开密钥进行的加密，只有其对应的私有密匙才能解密。用私有密钥进行的加密，也只有用其相应的公开密钥才能解密。
Electronic information encryption technology to transfer to secure role. In the transmission of electronic information, the encryption key or the algorithm of the encrypted information sent by the sender, if in the process of transmission is the theft of information, he can only get ciphertext ciphertext, it is impossible to understand. Accept that can use the decryption key to ciphertext decryption, back into plaintext.
加密技术对传送的电子信息能够起到保密的作用。在发送电子信息时，发送人用加密密
钥或算法对所发的信息加密后将其发出，如果在传输过程中有人窃取信息，他只能得到密文，密文是无法理解的。接受着可以利用解密密钥将密文解密，恢复成明文。
With the development of network technology, some spam, viruses and Trojan online hacker of network security has caused great threat. Enterprise information so that the network was similarly threatened the security of electronic information, enterprises are difficult to be guaranteed. In view of the network is not safe to this condition, a measure of protection to initially take is the firewall. In our personal computer in the firewall also played a big role, it can prevent the intrusion of non computer hackers, information tampering.
随着网络技术的发展，一些邮件炸弹，病毒木马和网上黑客等对网络的安全也造成了很大的威胁。企业的信息化使其网络也遭到同样的威胁，企业电子信息的安全也难以得到保证。针对网络不安全这种状况，最初采取的一种保护措施就是防火墙。在我们的个人电脑中防火墙也起到了很大的作用，它可以阻止非黑客的入侵，电脑信息的篡改等。
Message authentication and authentication are two forms of authentication, message authentication is mainly used to ensure the integrity and non-repudiation of message authentication, the user through to identify true and false information and whether the third party to modify or forge. Identity authentication and identification of the identity of the user, including the identification and validation of two steps. Clear and distinguished visitor status is identified, confirmed the user identity is verified. Users accessing some non public resources must pass authentication. For example, check the system access to universities, must go through the test number and password to access. Some of the resources of university library to the campus network can access, non campus network can not enter, unless paid for a qualified access identity.
消息认证和身份认证是认证技术的两种形式，消息认证主要用于确保信息的完整性和抗否认性，用户通过消息认证来确认信息的真假和是否被第三方修改或伪造。身份认证使用与
