They may be used to create digital signature and construct key exchange protocols, too. A comprehensive end-to-end key agreement and authentication protocol based on Elliptic Curve Cryptosystem (ECC) may be adopted to satisfy the security requirements in virtual class application. This paper adapts an

The transmission of binary and text file using OFDM with its protocol as well as system parameters have been explained in detail. This technique has high transmission rates over wire line and wireless channels with protection from multipath fading which can turn out to be a predicted technique in fourth Generation (4G) mobile phones. It is an Ideal technique for bandwidth hogging applications like Video Conferencing, DAB, DVB, etc. Multi-user capacity possible using MC-CDMA. For the most part, Orthogonal Frequency Division Multiplexing (OFDM) is the standard being used throughout the world to achieve the high data rates necessary for data intensive applications that must now become routine. The bit error rate and the ISI in multipath environment in conventional techniques such as QAM are very high which can be reduced by implementing the OFDM technique Also, in the paper result of simulation, future work and conclusion has been provided.
