# Review of Physical Layer Security in 5G Wireless Networks
## 3 Literature Review
The firmware implementation, which can be used on a range of IoT devices and is immune to side-channel attacks, is the most dependable architecture for the Grostl hash function. The hardware and software platforms used in this work include FPGAs, ARM Cortex-A processors, and ARM Cortex-M4 CPUs. Several lightweight hash algorithms are tested for performance on different platforms in the article. The authors of study [36] introduce a novel technique for fault diagnostics of the low-energy Midori cipher, as proposed in the work by [PERSON] et al. (2023) titled \"From Unbalanced to Perfect: Implementation of Low Energy Stream Ciphers.\" By analyzing the statistical output of the encryption, the technique identifies errors resulting from flaws in the Midori cipher. The suggested approach is evaluated using multiple Midori implementations, demonstrating a high level of accuracy in fault detection without significantly increasing overhead. The paper concludes that this promising method should be employed to enhance Midori's security. Additionally, the research presents a new implementation of a low-energy stream cipher specifically designed for the ARM Cortex-M4 CPU. The RECTANGLE cipher's fault diagnostics is paper [37]'s main topic. A compact block cipher developed for devices with limited resources is the RECTANGLE cipher. The bitslice architecture and substitution-permutation network (SPN) are the foundations of the cipher. The study suggests a brand-new hardware RECTANGLE implementation. The bitslice architecture is the foundation of the suggested implementation. A form of architecture known as bitslice divides the encryption into manageable pieces and implements each block concurrently. A range of hardware platforms have been used to assess the suggested implementation. The evaluation's findings demonstrate that the suggested implementation is effective and suitable for use on a range of devices with limited resources. The paper also suggests an innovative approach to RECTANGLE fault diagnosis. The approach is based on the finding that RECTANGLE flaws can lead to incorrect output from the cipher. The technique analyzes the output of the encryption statistically to find errors. The suggested approach has been examined on numerous RECTANGLE implementations. The evaluation's findings demonstrate that the method has a high degree of accuracy in fault detection. The technique is effective and does not significantly increase the cipher's overhead. The proposed method is a potential new approach for RECTANGLE fault diagnosis, the paper finds. The strategy should be utilized to increase RECTANGLE's security, according to the report.On this platform, the article suggests a brand-new hardware implementation of the RECTANGLE algorithm.
