Secure Teaching Support System Using FTP Protocol

File Transfer Protocol (FTP) is the standard mechanism for copying a file from one host to another. Transferring file from one computer to another is one of the most common tasks expected for networking and internetworking environment. This thesis is intended to implement teaching support system for Computer Universities by using FTP.This system can assist the teachers in Computer Universities to cooperate over the network. It can deliver the ability to manage and access teaching materials. The teaching materials contains sample questions, sample answers, exam scope, lecture plan, postgraduates scope, other solutions and important information .While transferring files over network, it is needed to provide security for some important information. To provide the security, the system is implemented by using ElGamal Algorithm. The system uses a network operation system design to manage the entire network from a centralized point, (server).Sever has to transfer encrypted files over the network. On the receiving site, the encrypted files must be decrypted by the client to get the original data. Therefore the system can transfer files with the help of File Transfer Protocol and provides security using ElGamal algorithm
