Abstract: The security of wireless communications using solar energy is computed in this article. The source S recovers energy from sun to forward data to the destination D. The eavesdropper will receive the data and tries to decode it. The strictly positive secrecy capacity (SPSC) and the secrecy outage probability (SOP) are computed when the source recovers energy from sun. We study the evolution of SOP and SPSC with respect to the hour t when the source recovers energy from sun. The SOP decreases and the SPSC increases at t = 11 versus t = 9, 7 AM as the recovered energy is very large. The security enhances as the harvesting time 0 < χ < 1 increases. The security enhances as S is close to D. The security of wireless communications using solar energy was not yet derived. We also enhance the security by adding simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STARRIS) between S and D. The use of STAR-RIS enhances the secrecy outage probability by 10 and 30 dB when 8 and 12 reflectors are used.

Keywords: solar energy; security; STARRIS; strictly positive secrecy capacity; SPSC; secrecy outage probability; SOP.
