A Novel Multilayered Encryption Model Featuring Dynamic Randomization and Adaptive Key Integration

The rapid advancements in technology have significantly increased the risk of attackers decrypting confidential data, posing serious security threats. Conventional encryption methods, while effective, may fall short in deterring sophisticated decryption attempts. This research introduces an innovative multilayered encryption/decryption method designed to enhance the security of existing encryption algorithms. The proposed technique employs a three-layered approach. In the first layer, the original text undergoes dynamic randomization using a unique Confidential Randomization Key to ensure unpredictability. The second layer applies a conventional encryption algorithm such as DES or AES to the randomized text. Finally, in the third layer, main features extracted from a confidential image are utilized as a private key to further encrypt the data. On the receiver's end, the decryption process reverses these steps to reconstruct the original text. By combining multiple layers of security, this approach enhances encryption robustness, making unauthorized decryption significantly more challenging, and offer a scalable solution adaptable to varying security requirements.
