File Transfer Protocol Manager

Computer Science and Engineering

File Transferring Protocol(FTP) has been extensively used for many years. Despite, there occur some vulnerability in the protocol. For Example, the passwords, files, and other confidential data are transmitted in unencrypted form that is in plaintext. Albeit some new FTPs like FTPS (File Transfer Protocol Services) have been recommended and are been used to overthrown the known vulnerabilities, there are many flaws, such as lack of tractability in use, unable to meet unequivocal security requirements. Given these fact, the FTP and its prerequisite requirements are studied rooted and a new 'SCSN'(Secure Client Server Network) system. A modern SCSN system is recommended upon combination of dynamic password, face recognition, thumb recognition technology as well as hash function and symmetric key algorithms and etc. to obtain its high efficiency and security. The security level selection mechanisms ratify to meet each and its own security requirements. The resource access control mechanism is used to prevent server from unauthorized access attacks. Analysis shows that compared with previous and existing FTP systems, the new system makes not only data transmission but also system in use user friendly, more tactile and efficient.
