“…Because satellite communication has many advantages, such as long communication distance, small restrictions and flexible signal configuration, it is widely used in communication broadcasting, secure communication, positioning, navigation and other fields [1][2][3][4][5][6]. However, since the essence of satellite communication is wireless communication, the main problem is that communication signals are easily exposed to illegal interceptors in the process of wireless transmission, and the rapid improvement of computer data processing capabilities now means that the anti-interception ability of communication signals has improved.…”

Security has always been an important aspect of wireless communications. Aiming at further improve the security of wireless communication and how to prevent eavesdropping, this paper proposes a constellation encryption design based on chaotic sequence and the RSA algorithm. The core idea of this method is to effectively combine both chaotic sequences and RSA, and then to generate large number of encrypted sequences with high security. The specific method is to first use the asymmetric RSA algorithm to transmit the system parameters, then to use the initial value sensitivity of the chaotic sequence to generate the secret sequence, and finally to use the secret sequence to encrypt the original sequence. Simulations show that the proposed algorithm further improves the security of satellite communications without increasing the complexity of the original system.

“…5 Besides, a PLS-based multi-antenna satellite communication resource optimization method was studied for various receivers with different speed and transmission rate requirements. 6 In particular, when collusion reception mode was adopted by multiple legitimate receivers and eavesdroppers, the influence of channel estimation error on the security performance of satellite-terrestrial downlink communication was studied. 7 In addition, the authors in Reference 8 solved the information security problem in the scenario where the eavesdropper is closed to the legitimate receiver with near-ground jammers transmitting artificial noise (AN) signals.…”

The satellite-terrestrial downlink transmissions with larger coverage areas face more severe security challenges than terrestrial cellular communications due to the limitation of the satellite's power and the complexity of the channel. In this paper, the system model consists of one satellite, one legitimate user and multiple randomly distributed eavesdroppers while taking into account practical hardware impairments (HIs) at all transceivers involved. The Shadowed-Rician fading model is adopted since it is a perfect fit for the satellite-terrestrial channel.Besides, the full-duplex (FD) operation is introduced in the destination where the receiver acquires the information signal and simultaneously emits the artificial noise (AN) to interfere with the nearby eavesdroppers. The maximal ratio combination scheme is applied to the destination to improve security. To facilitate evaluation of the effect of various parameters on the security performance, the closed-form expressions of secrecy outage probability and ergodic secrecy capacity for the system are derived under the stochastic geometry framework.Finally, the simulation results show that the AN plays a pivotal role in improving the security performance, while the HIs can greatly deteriorate the performance, especially in the high transmit power regime. In addition, compared with the traditional half-duplex receiver, the FD receiver have better security performance and can significantly alleviate the performance deterioration caused by HIs.

In low-earth-orbit (LEO) satellite-to-ground communication, the size of satellite antennae is limited and the satellite motion trajectory is predictable, which makes the channel state information (CSI) of the satellite-to-ground channel easy to leak and impossible to use to generate a physical layer key. To solve these problems, we propose a key generation method based on multi-satellite cooperation and random perturbation. On the one hand, we use multi-satellite cooperation to form a constellation that services users, in order to increase the equivalent aperture of satellite antennae and reduce the correlation between the legal channel and the wiretap channel. On the other hand, according to the endogenous characteristics of satellite motion, a random perturbation factor is proposed, which reflects the randomness of the actual channel and ensures that the CSI of the legal channel is not leaked due to the predictability of satellite motion trajectory. Simulation results show that the proposed method can effectively reduce the leakage of the legal channel’s CSI, which makes the method of physical layer key generation safe and feasible in the LEO satellite-to-ground communication scene.
