Special Issue: Securing 5G and Beyond Networks with Physical Layer Security

Theme and Scope

Telecommunication networks are growing tremendously around the globe. To meet the increasing communication needs, 5G and beyond networks have evolved. The features of 5G and beyond networks provide immense opportunities to create intelligent and seamless fast communication services. Beyond their healthy potentials, they suffer from security issues as well. Providing resilient security services is given the highest priority while the design of these modern networks. Some of the security issues that are possible in 5G and beyond networks are eavesdropping, unauthorized access, and demolishing integrity. A few of the open security challenges in 5G and beyond networks are lightweight security, scalability, low latency, and reliability. Traditional techniques such as cryptography can be used to provide security services. But there are few issues in cryptographic methods. First, the crypto functions require complex signal processing. Second, the centralized key distribution leads to increased delay. Thus, the cryptographic methods cause communication overhead. Instead, the physical layer security utilizes the properties of the transmission channel and acquires security.

The prominent advantage of physical layer security in 5G and beyond networks is the avoidance of centralized key distribution. Thus, it avoids the additional latency caused by key usage and serves with less complexity. A few of the performance metrics that are used to evaluate the efficiency of physical layer security are perfect secrecy, weak secrecy, strong secrecy, secrecy capacity, secrecy outage probability, security gap, reliability threshold, and rate interval. To tackle eavesdropping, transmission signal heterogeneity can be exploited. Much of the physical layer security is based on random-coding arguments. This code construction is an emerging research topic. The most prominent codes that are constructed to achieve physical layer security are LDPC codes, polar codes, and lattice codes.

In the future, to improvise physical layer security of 5G and beyond networks, the researchers could give much attention to wiretap coding, feedback policies design, and channel state information. Open research opportunities still exist in physical layer security threats such as signal cancellation attacks, unmanned aerial vehicle communication, millimeter-wave communication, full-duplex technology, synthesis of 5G characteristics, and visible light channel. This issue on Securing 5G and Beyond Networks with Physical Layer Security, gives an insight into the advantages of physical layer security in 5G, Beyond Networks, and delivers the future research directions for scientists and academicians.
