Secure File Transfer Using USB

Universal Serial Bus (USB) devices are high transmission speed external devices. USB is the speediest external device available today. The access to USB is very simple, convenient and fast compared to other external devices such as CD, DVD, Floppy drive etc. Thus USB have become most popular interface standard for hardware connection. But from security point of view, USB devices lacks security as no user is restricted to access USB device. If we restrict the use of USB devices, then the data access through external devices would be as chaotic as before. Thus a system which would provide fast access as well as security is required. In this paper, we propose a system which deals with mutual authentication and key agreement in order to provide security for access through USB devices
