“…Strobel et al [129] presented a new model to extract malicious codes from the embedded system using the CPU electromagnetic emanation to prevent side-channel attacks in WSN and SWSN. To ensure the physical layer security of WSN and SWSN, Bang et al [130] proposed a secure cryptographic-enabled modulation technique for these networks. In this model, the authors used a random constellation mapping rule for packet transmission in the network instead of a pre-defined mapping rule such as "Gray-coded mapping" to guarantee the integrity of information during transmission from source to destination.…”

“…The approaches have included several methods ranging from scrambling/interleaving the IFFT coefficients [16], [17], changing the FFT size in pseudorandom manner and even changing the cyclic prefix along with FFT size in physical layer. Secure obfuscating of the interleaver stage and obfuscating the constellation mapping stage of OFDM pipeline are proposed respectively in references [18], [19].…”

<span lang="EN-US">Fifth-generation (5G) massive machine-type communication (mMTC) is expected to support the cellular adaptation of internet of things (IoT) applications for massive connectivity. Due to the massive access nature, IoT is prone to high interception probability and the use of conventional cryptographic techniques in these scenarios is not practical considering the limited computational capabilities of the IoT devices and their power budget. This calls for a lightweight physical layer security scheme which will provide security without much computational overhead and/or strengthen the existing security measures. Here a shift based physical layer security approach is proposed which will provide a low complexity security without much changes in baseline orthogonal frequency division multiple access (OFDMA) architecture as per the low power requirements of IoT by systematically rearranging the subcarriers. While the scheme is compatible with most fast Fourier transform (FFT) based waveform contenders which are being proposed in 5G especially in mMTC and ultra-reliable low latency communication (URLLC), it can also add an additional layer of security at physical layer to enhanced mobile broadband (eMBB).</span>

<p>This paper proposes a novel physical layer one-time pad (OTP) encryption scheme for modulated signals based on the wireless channel. By imitating the OTP encryption for bit sequence, the sufficient conditions of perfect encryption for modulated signals are provided and proved. Then, we provide a detailed process of the scheme in the wireless system. Since the plaintext is the modulated signal rather than the bit sequence, we use high-level quantized channel estimation samples as secret keys and design encryption functions for QAM and PSK signals. The theoretical proof and Monte Carlo simulation results show that the proposed scheme can achieve perfect secrecy by designing the ciphertext signal independent of the plaintext signal. Furthermore, the simulation shows that the error probability of the proposed scheme is lower than that of the current mainstream physical layer encryption scheme because the quantization level is optimized according to the signal-to noise ratio.</p>
