Abstract
The tremendous growth of LTE in wireless communication requires a fast, reliable system with the high-performance approach. In modern life, using OFDMA and SC- FDMA as the multiple access technique, the impact of long- term evolution (LTE) has increased. Lack of awareness of recent trends and technology makes a significant impact on the risk of security. This article is to establish a secure communication channel for audio transmitting and receiving devices. There are many algorithms available for encrypting the data. One of the encryption algorithm is a chaotic algorithm which is more secure, fast and reliable. This approach can be used for applications, where high data security is required such as military applications. This article proposes a robust authentication mechanism by using a chaotic audio encryption algorithm in the SC-FDMA system to improve data security. Transmission and reception of encrypted audio data over the SCFDMA system will be tested using MATLAB. The performance analysis is based on the SNR, PSNR, MSE, Entropy, Histogram and Bit Error Rate (BER) signals.
