Investigating the Impact of Secure Image Transmission over MIMO-OFDM System
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 4
Abstract
Abstract: The paper implements secure MIMO-OFDM systems to achieve the data confidentiality using the following three different cryptographic techniques, namely, AES block cipher, RC4 stream cipher and the proposed Partial Selective Encryption (PSE). These implemented systems have been investigated using PC withprocessor corei7, 6G RAM and running on Windows 10 as operating system. The investigation involves the measure of the impact of security and quality on the transmission of encrypted images between parties in the MIMO-OFDM wireless domain. The simulation results show the system performs well, the security of the system has been enhanced, and the good point is the enhancement of the Bit Error Rate (BER) by (1.5-1.9) dB. The results also show the secrecy of the transmitted image is achieved from the randomness and cross-correlation results between the original and the transmitted images. Furthermore, the results show that the AES and PSE perform better in terms of BER and privacy whereas the RC4 gives better results in terms of delay and Peak Signal to Noise Ratio (PSNR) compared to AES whereas the PSE gives a compromise results
