摘要

Based on broadcast transmission, the future Fifth-Generation networks, 5G, suffer from a critical threat, which is the eavesdropping. This issue can be fixed with the cryptographic protocols. Nevertheless, this method is complex and challenging because of the active topology of wireless networks, which does not permit effective management of security keys. Recently, Physical Layer Security (PLS) method is applied as an alternative solution to mitigate the privacy problem, where the characteristic of the physical layer schemes, namely the modulation, Massive Multi-Input Multi-Output (m-MiMo) and channel coding are exploited to ensure privacy. The fountain code is one of these methods where the legitimate receiver must recover the message before eavesdropper did. However, this feature cannot be exploited in 5G networks in the presence of an intruder using the m-MiMo. Furthermore, the design of Artificial Noise (AN) needed in m-MiMo involves a computational complexity and excessive consumption of energy that complicate the secrecy management for fountain code. In this article, we propose a new method to avoid this problem by judiciously exploiting the features of both technologies. The new approach uses the Raptor code feature, as considerably as the m-MiMo parameters aided by AN signal while reducing the transmission power of the AN. The numerical results indicate that the new approach ensures the protection of legitimate users on the channel and minimizes energy expenditure, which potentially gets to this proposed method a greener and secure transmission.
