Design of Secure File Transfer over Internet

Abstract: Due to the recent innovations in the internet and the network applications and the wide spread of internet and networks, it is now completely possible to conduct electronic commerce on the internet or through the local area networks, and the wide spread of computer and communication network promoted many users to transfer files and sensitive information through the network, this sensitive data requires special deal. This work presents a security system that can provides privacy and integrity for exchanging sensitive information through the internet or the communication networks, based on the use of recently developed encryption algorithms, such as AES, IDEA and RSA. The aim of the work is to develop a simple file transfer system that can obtain privacy, integrity and authentication for the file transfer process. The proposed system uses symmetric cryptography system. File transfer must provide end-to-end visibility, security and compliance management.
