Securing Data Transfer using Parallel Encryption Based on Different Metadata

In the digital age, the security of multimedia data on disk drives is increasingly vital, as data volumes grow rapidly and security threats evolve. Current cryptographic methods, such as RSA-2048, though widely used, present significant limitations. RSA-2048 is computationally intensive, resulting in slow encryption and decryption speeds, which can be impractical for large volumes of multimedia data. Additionally, the RSA-2048 algorithm has vulnerabilities that may allow tampering, posing a threat to data integrity and confidentiality. These shortcomings, combined with the lack of flexibility and constant manual input required from users, make it less suitable for modern applications demanding high efficiency and robust security. The proposed system aims to solve these issues by introducing the XChaCha20 algorithm, a more advanced cryptographic approach. XChaCha20 is known for its high speed, lightweight nature, and ability to handle large-scale data encryption more efficiently. By leveraging parallel encryption and decryption processes, this algorithm significantly reduces the time needed for securing data, making it more suitable for real-time applications. In addition to improving speed, XChaCha20 provides stronger encryption, reducing the risk of tampering and enhancing data confidentiality. Its design allows for better scalability and performance, especially when dealing with the increasing demands of multimedia storage. Overall, the XChaCha20-based system provides a more secure, efficient, and user-friendly alternative to RSA-2048, meeting the demands of modern data security challenges while reducing the computational burden
