Secure Visible Light Communication Technique Based on Asymmetric Data Encryption for 6G Communication Service

Abstract

Security in residential and business establishments has become an area of considerable importance. To provide enhanced security using conventional visible light (VL) communication, the characteristics of which allow for easy access by nearby intruders, a new VL communication technique is proposed in this paper. The novel VL communication system is based on a data encryption method using asymmetric encryption, and it is proposed for use in smart indoor services in the 6th generation communication environment. The asymmetric encryption capability is studied by comparison with the conventional technique, the optimum key length for the public or private encryption codes is determined under the criterion of the minimum estimation error. Moreover, the error performance is analyzed with various RSA encryption keys and data lengths to verify the performance of the proposed technique. A real experiment is performed to evaluate the proposed technique using an implemented test bed, and the success rates of the VL communication technique with and without RSA coding are evaluated by a real experiment with a test bed under an indoor laboratory VL channel. We believe it is evident that the VL communication technique based on asymmetric encryption yields superior error performance compared to that without encryption for optimal lengths of the encryption key and data bits.

“…Author suggest the use of WBPLSec protocol based VLC can be used transact secret shared key between authentic receiver and devices in an indoor environment. Lee [300] also targeted to improve the security of VLC communication system tailored for smart indoor services in 6G ear. Author proposed the use of asymmetric Rivest-Shamir-Adleman (RSA) encryption for securing data communication and for exchanging secret key.…”

“…Therefore, VLC is considered as a potential medium for handling 6G-based high-throughput applications. In [73], the authors suggested use of asymmetric encryption for optimum error rate in comparison to conventional symmetric encryption in 6G-enabled VLC-based indoor applications. 6G technology is being designed with the aim to achieve a 1Tbps throughput with less than 100us latency.…”

Water-Wave Effect on the Encryption and Deep-Learning-Based Recognition of a Speech Signal Transmitted Over a Wireless Optical Communication Channel

“…Lastly, it is interesting to investigate how an encrypted audio signal is affected by water-waves. It should be mentioned that there are many types of encryption schemes used for WOC and UWOC, such as chaotic maps [19], virtual optical holographic [43], temporal ghost imaging [44], and Rivest-Shamir-Adleman (RSA) [43] [45]. We encrypted the analog audio signal in MATLAB 2021a by using the asymmetric RSA scheme [46], [47] due to its known superior performance in WOC [45].…”
