Abstract

The digital age relies heavily on file sharing, which has become more important with the increasing use of digital data and the Internet. Along with this increasing importance come major and widespread security issues, especially for files containing sensitive or vital data, such as those related to commercial, military, or healthcare sectors. The most common and effective way to protect the security and privacy of shared files containing sensitive information is still encryption. With the development of high-efficiency devices and massive processing capabilities, traditional encryption methods are increasingly under pressure from modern computer security threats, particularly quantum computing. This study aims to raise resistance against these security concerns by proposing a dynamic encryption system based on DNA (Deoxyribonucleic Acid) encryption. DNA bases are selected to encrypt data dynamically and based on the key in the proposed system. Then, another level is added using (Ribonucleic Acid) RNA, which includes 256 * 256 different bases that are also selected dynamically. This makes this algorithm more effective in dealing with modern security attacks, including those from quantum computers. The results demonstrate the system’s ability to encrypt and decrypt various types of files while providing a strong defense against conventional attacks. Furthermore, because the system is dynamic, it provides enhanced protection against attacks by contemporary quantum computers due to the wide range of encryption rules. This makes it almost impossible to guess or test every potential vulnerability. The suggested cryptosystem also produces reduced file sizes and is more time-efficient. The performance findings show that processing times for various file types closely converge, with an average throughput between 38,000 and 47,000 bytes per second.
