Abstract: This paper introduces new techniques for improving the security level of the wireless optical systems. In this way, we are going to use modulation schemes based on spread spectrum theory. These techniques had been developed for military applications in order to obtain reliable and secure communications, so they seem to be a good candidate for our systems. Spread spectrum systems perform a data encryption in the modulation process, and they are able to work in presence of high level interference and intentional jamming signals. On the other hand, these schemes can be also applied to optical barriers and perimeter control systems, because the spread spectrum signal improves the robustness and invulnerability of the security barriers.
