Abstract: In this paper, we propose a security approach in the physical layer based on Turbo code and the changeable secret key to enhance the reliability and security of the multiple-input multiple-output (MIMO) wireless communication systems. The secret key created from complex impulse response (CIR) between authorised users is simultaneously used to manage the Turbo code's interleaving and puncturing blocks. The proposed scheme is implemented in the MIMO systems via Rayleigh fading. The results from system simulations and security evaluations demonstrate that the proposed scheme provides greater efficiency for MIMO systems compared to that of the standard Turbo code. Moreover, it successfully provides good concealment and prevents attacks on digitally encrypted images. Therefore, this proposed method is ideal for use in actual MIMO systems. By using the proposed method, the system can jointly perform data security and error correction functions without altering the transceiver's physical design.

Keywords: session key; turbo code; interleaving block; puncturing block; image encryption; MIMO.
