Design And Implementation Of Net Safety Deposit Box System

Internet has already gone into our daily life with the science becoming greater. Network already has been more important in people's daily life with the development of the broadband network and Universal of the Internet.So it is a very important subject that how to ensure the Internet stability's and security's operation effectively. And it is also a problem that makes the network administrator headache. Now many kinds of virus are rampant and attack endless. With the administration loophole and anthropogenic damaged, it is afraid to imagine that what it would be while these computers are Hackers penetrated, malicious damaged, obstruction. Hackers stolen bank card ID and password and important personal information that bring panic for the network users. Net Safety Deposit Box is the security software for the problem.Net Safety Deposit Box expands the application of the Internet and provides security, free, convenient information access space. This can also reduces the trouble for the user who is carrying thick notebook computers and increases a new preservation of personal data channels. Whether you are in or out, in the office or in the hotel, at home or in the wild, if you can connect to the internet by using the Internet tools anywhere, you will open the Net Safety Deposit Box through input the ID and password. You can get the information or save the information. In an increasingly competitive society, more comfortable is more competitiveness. Net Safety Deposit Box can help you catch the business opportunities and create a glorious future. Now Net Safety Deposit Box is only the starting stage in China.QiHu360 Net Safety Deposit Box, RuiXing Net Safety Deposit Box, HeZhong Net Safety Deposit Box, Geer Net Safety Deposit Box are the famous in China. This article analysis and understands the Net Safety Deposit Box which are at home and abroad function. Then designed and developed to achieve Net Safety Deposit Box, independently. Net Safety Deposit Box system's function is including registered users, verified the identity of users, user information management, encrypted data transmission, data storage.The entire system uses B/S design method and the J2EE standard MVC architecture design. Server part uses JavaBean to operate the database and data transmission uses Servlet. Web show uses JSP. Browser part uses Apple to designThis system's technical features is based on password EKE protocol. It is more secure and convenient than the general system.MVC structure is based on Model-View-Control design patterns. This pattern integrates JSP and Servlet and is good for the big structure web application.Key Agreement is a sending information security method without exchanging key. It relies on public-key and private-key. The key isn't used to encrypt but use for creating shared key. The shared key is used for creating session key.Symmetric Key Encryption is also called Secret/Dedicated key encryption. People must use the same symmetric key encrypt the express and decrypt express each other.Asymmetric Key Encryption is also called public key encryption. It means that each one only has a pair of key that are public-key and private-key. The public-key is open and private-key is secret. Using public-key encrypt and only using private-key decrypt. The one who sending the data uses the other's public-key encrypt the message and receiver uses his private-key decrypt. The public key encryption technology that solved the key published and management problem is the core of the business code. The parties that communicate data may safety confirm the ID and public-key by using the public key encryption technology. Asymmetric key solved the problem that establish agreement key before sending message.EKE Protocol is encryption key exchange protocol. It makes communication both sides use sharing key to exchange key's information in the unsafe network environment. It can also prevent key guessed offline attacks.The entire system is divided into Server part and Browser part according to technology. Following introduce the system function and structure.The Server is primarily responsible for generating the exchanged key, responsing to the user's request, processing information, administrating database.The Browser is primarily responsible for generating the shared key, generating the asymmetric Key, displaying information.Chapter One introduced the Net Safety Deposit Box significance, application and development trend. The application is QiHu360 Net Safety Deposit Box, RuiXing Net Safety Deposit Box, HeZhong Net Safety Deposit Box, Geer Net Safety Deposit Box. Chapter Tow introduced technology and concept. Included network security, key technology, EKE Protocol, MVC Structure. Chapter Three introduced Net Safety Deposit Box system's architecture, network logic, function, processing and security, runtime environment. Chapter Four introduced Server design and implementation, included Server architecture, Server structure, Server implementation, Server processing. Chapter Five introduced Browser design and implementation. Included Browser architecture, Browser implementation, Browser processing. Chapter Six introduced database's design and implementation. Included table structure and table relations。Now Net Safety Deposit Box is at the initial stage, but it will have very promising future. In the network security world, everyone all care privacy network security, so it must be more and more user like to use the Net Safety Deposit Box with the function increasing. Once user authorized the Net Safety Deposit Box, most network application software will connect to Internet by using Net Safety Deposit Box. So this service market future is incalculable.
