Efficiency in the field of communication is of utmost importance. The efficiency in data transfer is obtained by encrypting the data primarily for security by using the Rivest Shamir Adleman (RSA) encryption algorithm. The RSA encryption provides the data with security by utilizing separate keys for the process of encryption and decryption. Post encryption, the result is encoded using the Reed Solomon (RS) encoding scheme. The added advantage of this encoding scheme is its error detection and correction scheme in addition to the productive bandwidth usage. The data is encoded from the source and will be modulated using Quadrature Amplitude Modulation (QAM) scheme. The modulated data can then be transmitted. The use of modulation improves the reception quality and ensures no signal mixing occurs. In the receiving end, the received signal is demodulated, decoded. The errors are detected and corrected in case if present. In this paper errors are introduced by the user to demonstrate the error detecting and correcting capabilities. The decoded data is then decrypted to obtain the original data. The entire set up is simulated on the MATLAB software.
