Abstract
It is important to pay attention to develop our security systems, due to the increase in cyberattacks and the development of their methods and the work to develop quantum computers capable of penetrating the solution of complex equations of encryption algorithms. The need to develop protection methods has emerged in line with the development of hackers to ensure the security and safety of users' data. In this research, work was done on the modern Li-Fi technology based on comparing the values with Kim's model and a distance of more than 13 km was reached in the fresh air. This technology provides security and privacy inside rooms because it sends signals through light, so the signal cannot be modified from the outside. However, the threat remains through the transmission medium. Therefore, a hybrid algorithm was created from chacha20 with a key size of 256 and RSA with a key size of 2048, which guarantees us a high level of security, making it immune to threats. The chacha20 algorithm provides encryption speed and security, while the RSA algorithm increases the level of security of the algorithm, as the total time taken to encrypt data from the sender and decrypt it from the receiver was 0.036 seconds. This ensures high and fast performance for this hybrid algorithm.
