The keys to holographic data security

Presents three encrypted holographic memory systems. These systems are secure because the total number of mathematical possibilities of the multidimensional keys, which consist of two-dimensional phase masks, their three-dimensional positions, and wavelengths of light, is extremely large. The experimental results are very encouraging. We expect the encrypted memory system to play an important role in ultrafast secure communication systems using the spatial-temporal converters with ultrahigh speed of more than Tb/s.
