“…The encryption in a layered communication model such as TCP/IP can be performed at different levels of the communication, such as in layers 2 or 3 with MACsec or IPsec standards, respectively. Although encryption in physical layer (layer 1) is less usual than in other layers some proposals have been made, for example related with photonic [26]- [29] or radio [30], [31] technologies or with the physical layer protocols [20], [21], [32].…”

In some encryption systems it is necessary to preserve the format and length of the encrypted data. This kind of encryption is called FPE (Format Preserving Encryption). Currently, only two AES (Advanced Encryption Standard) modes of operation recommended by the NIST (National Institute of Standards and Technology) are able to implement FPE algorithms, FF1 and FF3. These modes work in an electronic codebook fashion and can be configured to encrypt databases with an arbitrary format and length. However, there are no stream cipher proposals able to implement FPE encryption for high data rate information flows. The main novelty of this work is a new block cipher operation mode proposal to implement an FPE algorithm in a stream cipher fashion. It has been called CTR-MOD and it is based on a standard block cipher working in CTR (Counter) mode and a modulo operation. The confidentiality of this mode is analyzed in terms of its IND-CPA (Indistinguishability under Chosen Plaintext Attack) advantage of any adversary attacking it. Moreover, the encryption scheme has been implemented on an FPGA (Field Programmable Gate Array) and has been integrated in a Gigabit Ethernet interface to test an encrypted optical link with a real high data rate traffic flow. INDEX TERMS FPE (format preserving encryption), stream cipher, FPGA (field programmable gate array), Ethernet.

“…Also, considering that the AN transmitted by receiver and the signal transmitted by transmitter are through independent channels, the ZF operations of AN won't affect the precoding matrix V and decoding matrix U. Thus, after IA is performed, the transmission rate of receiver k can be expressed as (21) When the CSI between receiver and eavesdropper is unknown at the eavesdropper, the most appropriate way of the receiver is to send Gaussian white noise with the same band of transmitting signal. Thus, the received signals at the eavesdropper can be rewritten as…”

In this paper, a new security and green communication scheme is proposed to the Interference-Alignment (IA) based networks. To achieve a secured communication, full-duplex receivers are utilized to transmit artificial noise (AN). Both the signals and the ANs are used to harvest energy to realize green communication. For these reasons, the feasible conditions of this scheme are analyzed first. Secondly, the average transmission rate, the secrecy performance and the harvested energy are investigated. Thirdly, an optimization scheme of simultaneous wireless information and power transfer (SWIPT) is given to optimize the information transmission and the energy harvesting efficiency. Meanwhile, an improved IA iteration algorithm is designed to eliminate both the AN and the interference. Furthermore, relay cooperation is considered and its system performance is analyzed. The simulations show that the target average transmission rate is not affected by AN, while the secrecy performance can be greatly improved. The energy harvesting efficiency is also better than the traditional schemes. As expected, the average transmission rate further is improved with the relay cooperation. Index Terms-Artificial noise (AN), eavesdropping, interference alignment (IA), relay, secrecy, simultaneous wireless information and power transfer (SWIPT) I. INTRODUCTION HE broadcast characteristics of the wireless communication networks (WCNs) determine that it is an open communication environment. The sharing of its information medium leads to intricate electromagnetic radiation problems. Of these, multiuser interference, wireless transmission secrecy and radio signal enabled wireless power transfer are intensively discussed in these WCNs [1]-[3].  Interference exists widely in multiuser WCNs, and this affects multiplexing rate of time slots, frequencies, and code space, which severely limits the reusability of channel resources and reduces the spectrum of networks.

“…Security solutions for 5G networks at physical layer are probably the most reported technologies. Although, as previously said, most works are analyzing the security threats, challenges and opportunities [ 44 , 45 , 46 ]; some specific technologies have been reported. In particular, technologies based on different channel estimators to prevent spoofing attacks in the wireless media have been described [ 47 ].…”

Future 5G networks are characterized by three basic ideas: enhanced mobile broadband communications, massive machine-type communications, and ultra-low-latency communications. Any of these requirements needs, to be fulfilled, the implementation of high-efficiency technologies at all levels. This includes some of the costliest mechanisms in terms of computational time and bitrate: information protection solutions. Typical techniques in this area employ complex algorithms and large protocol headers, which strongly reduces the effective baud rate and latency of future 5G networks and communications. This is especially relevant in the access network, which in 5G networks will follow a cloud-based architecture, where thousands of different devices must communicate, before aggregating all those streams to be sent to the backbone. Then, new and more efficient mechanisms are needed in the cloud radio access networks (C-RAN) for future 5G systems. Therefore, in this paper it is proposed a novel information protection scheme for C-RAN architectures based on resonant phenomena in optical fibers communicating the fronthaul and backhaul in 5G networks. Resonant structures and physical nonlinearities generate a chaotic signal which may encrypt and hide at physical level every communication stream in a very efficient manner. To evaluate the proposed mechanism, an experimental validation based on simulation techniques is also described and results discussed.
