“…OFDM, which has a high spectral efficiency and easy implementation, is used as a self-encryption via the constellation rotation principal. It has been incorporated into different protocols including IEEE 802.11 a/g/n, IEEE 802.16 WiMAX, the frequency domain [ 29 , 30 , 31 ], data scrambling in the time domain [ 32 ], rotation of the modulation symbols [ 33 ], and noise-enhanced constellation rotation [ 34 , 35 ] for many of these reasons. Research has looked at using PLE, such as constellation scrambling, to increase the security level of OFDM.…”

In this paper, a new physical layer authenticated encryption (PLAE) scheme based on the multi-parameter fractional Fourier transform–Orthogonal frequency division multiplexing (MP-FrFT-OFDM) is suggested for secure image transmission over the IoT network. In addition, a new robust multi-cascaded chaotic modular fractional sine map (MCC-MF sine map) is designed and analyzed. Also, a new dynamic chaotic biometric signature (DCBS) generator based on combining the biometric signature and the proposed MCC-MF sine map random chaotic sequence output is also designed. The final output of the proposed DCBS generator is used as a dynamic secret key for the MPFrFT OFDM system in which the encryption process is applied in the frequency domain. The proposed DCBS secret key generator generates a very large key space of 22200. The proposed DCBS secret keys generator can achieve the confidentiality and authentication properties. Statistical analysis, differential analysis and a key sensitivity test are performed to estimate the security strengths of the proposed DCBS-MP-FrFT-OFDM cryptosystem over the IoT network. The experimental results show that the proposed DCBS-MP-FrFT-OFDM cryptosystem is robust against common signal processing attacks and provides a high security level for image encryption application.
