Resumen:

The area of optical color picture encryption has recently emerged as one of the most talked-about subjects in the pitch of data security. Although it has been suggested that certain techniques used to encrypt color images, the majority of these techniques have traditionally been based on symmetric cryptographic modules. This paper present an alternate method for encrypting color images, which involves the utilization of an optical asymmetric cryptosystem. In this approach, we make use of a random modulus decomposition strategy in the gyrator domain, in addition to multiple wavelength and indexed picture methods. This allows to achieve optimal results. In order to establish fundamental characteristics for encryption keys, such as gyrator domain and decomposition masks P1 and P2. These fundamental parameters include, but are not limited to, random phase codes that are utilized by the optical cryptosystem. In addition, we have used this tool concurrently for the purposes of picture compression and encryption in order to achieve our goals. A performance analysis of the system has also been carried out, during which its sensitivity to a number of encryption factors, such as gyrator transform order and robustness, was evaluated. In addition, we have investigated the safety of the optical asymmetric cryptosystem while it is being used to decrypt information. In conclusion, we give numerical findings that verify the viability and efficiency of the optical cryptosystem for the encryption of color images.
