With the advent of novel Internet technologies it is clearly expected that most of them will have practical applications such as the recent Internet called Internet of Space Things. When this new technologies are running it is strongly expected the creation of private networks among satellites in order to optimize security when sensitive information is either uploading or downloading. In this paper a concrete idea to implement the information of solar photons to increase the quality of encryption processes is presented. Thus when photons energy are measured in space, this information enters as input at a BB84 quantum mechanics encryption scheme to maximize the security at the transference of information. Simulations are presented and discussed.
