A Physical-Layer Secure Coding Scheme for Indoor Visible Light Communication Based on Polar Codes
2018
IEEE Photonics Journal
Preserved Fulltext
In this paper, a secure coding scheme based on polar codes is proposed to simultaneously achieve physical-layer security and transmission reliability for indoor VLC systems under Wyner's wiretap model. ...
Since VLC channel is an open wireless channel, physical-layer security is desirable in order to hide secret information from unauthorized receivers, without reliance on upper-layer cryptographic techniques ...
In addition, Mukherjee et al. proposed a two-stage beamforming design to examine secret key agreement for MISO VLC systems [3] . ...
