Abstract
In this study, the chaos–hologram technique was used to encrypt information as one of the applications of holograms using MATLAB software. The results showed that the information to be encrypted using the computer-generated hologram technique can be easily de-encrypted using the computer-generated hologram reconstruction process. Therefore, this technology is not able to guarantee the confidentiality of information transmission from the sending unit to the receiving unit. When the computer-generated hologram technology is coupled with the chaotic Lorenz system by performing many arithmetic operations such as addition, multiplication, and division of two matrices of Fourier transforms of the information to be encrypted and the chaotic Lorenz system attractor, it is observed that there is a variation in the disappearance of the properties of the information to be encrypted and this depends on the type of computational process used. The results showed complete encryption of the information and the disappearance of its features using the mathematical division process.
