The growing demand for access to high-capacity wireless communication systems opens up the need for the alternative and complementary technology of optical wireless communications including ultraviolet (UV). In modern wireless communications networks the users and data security, which is extremely important in order to ensure users’ data protection and confidentiality, has become a hot topic. In this paper, we investigate security in a UV communications system by adopting two well-known coding schemes of low-density parity-check (LDPC) and polar codes (PCs). We show that the UV system with coding offers enhanced security performance compared to the un-coded system with the PCs offering a higher security level and a longer transmission span compared to the LDPC.
