Research Of File Transfer System Based On Security Isolation Architecture And SSL Protocol

In the information age,electronic document has become the main way of information storage,but it is easy to be stolen and tampered in the process of transmission.This can easily lead to the leakage of data.To solve this problem,this paper mainly studies GAP and SSL protocol.GAP can effectively protect the security of database with physical equipment,but the cost is high and flexibility is poor.SSL protocol can use key encryption technology to ensure the confidentiality of the data,but may be unable to know the key is damaged and decrypt invalid files,resulting in a waste of time.In order to combine the advantages and improve the disadvantages of the GAP and SSL protocol,this paper proposes a file transfer system based on security isolation architecture and SSL protocol.First of all,to ensure the security of database,a security isolation architecture is designed to isolate the client and server by software form and file is detected whether carrying virus or not.This not only saves costs,but also improves flexibility.Secondly,combining PKI technology with two-dimensional code technology,the user information is encrypted and transmitted.Besides,the identity of communicators are verified effectively.Database files are protected from the unknown identities.Then,the symmetric key integrity verification module is added based on the SSL protocol to ensure file transmission security and verify key integrity.This reduces the time cost of decrypting the scrambled file.Finally,the lossless compression algorithm and file block transfer technology are used to realize the fast file transmission.In this paper,the idea of GAP is realized in the form of software.This can effectively protect the security of database and improve the flexibility of application.Then,the SSL protocol is improved by adding key integrity verification module.This can not only guarantee the secure transmission of data but also verify the integrity of the key.Finally,the file transfer system based on security isolation architecture and SSL protocol is developed and implemented by using JAVA language,which is based on Eclipse8.0 as the development platform,SSH as basic framework and MySQL as database.The experimental results show that the file transfer system can guarantee the file transfer speed and the security of the database effectively.
