Advanced Threat Protection for File Storage
P. Neelakantan, Gangappa Malige · 2024
Cloud storage is widely used in various industries, but concerns about data security persist. Traditional techniques like cryptography and steganography have limitations and cannot provide sufficient security on their own. To address this issue, we propose a unique security system that combines multiple cryptographic algorithms and steganography. By using fast and secure symmetric key algorithms, such as AES and DES, along with the benefits of the asymmetric key algorithm RSA, we develop an efficient method to encrypt and decrypt data. This approach takes advantage of the strengths of each algorithm to create a strong encryption system that protects data from unauthorized access. Furthermore, incorporating splitting and merging techniques adds an extra layer of security. The LSB steganography technique is used to securely store essential key information. Implementing this comprehensive approach in the cloud environment not only enhances server security but also builds user confidence, as encrypted data is stored on a single cloud server. Overall, this sophisticated security mechanism offers enhanced data protection, making cloud storage a more reliable and secure option for various applications in different industries.
