Abstract

This project is to provide the secure file transfer encryption Java Application. This project consists of two application which is one application for server and another one application is for client. Client can send file to desire sender by uploading the file to the server. The file can want to be sent is the encrypted file that been encrypted by various of encryption method that been choose by the user itself. RSA has been chosen for key exchange and encryption of secret key if the encryption method that user choose is the symmetric encryption techniques. Nowadays, the transaction of transferring file has become widely use in daily working life in the organisation such as government agencies, and non – government organisation. These organisations using the file transfer and chatting between their staff every day. The most concern is how best the protection of their confidentiality of the sensitive data that transfer across the network. The problem is the secrecy and confidentiality of the sensitive information in organisation not well preserve. In additional, the integrity of the data in organisation not protected. Finally, the authentication of the message and file transfer in organisation not well authentic. The objective of this to develop the secure platform for user to encrypt and decrypt their files and message. Furthermore, to preserve the integrity of the file that transmitted in organisation. Another objective of this project is to provide the authentication method for organisation to authenticate the user, file and message. This project methodology is the Object-oriented approach. The methodology can be used because it provides the conceptual structure that assist to deal with the modelling the information system including development of its sub-system. The significant contributions for this project is the highly secure file transfer encryption platform for user to transfer and communicate with another user.
