Entropy Wall for Symmetric Cryptographic Key Generation Through Frame Processing

The entropy wall concept plays a vital role in ensuring the high degree of randomness and unpredictability necessary for robust cryptographic systems. Natural sources of entropy, such as the dynamic and non-reproducible properties of physical phenomena, provide a superior foundation for generating cryptographic keys. By leveraging such sources, one can effectively defend against potential vulnerabilities and emerging threats, including those posed by artificial intelligence and quantum computing. This paper introduces a method for generating encryption keys for AES 128 bits algorithm by utilizing entropy barriers from real-world sources, specifically video frames of juice being continuously shaken. By exploiting the inherent randomness of these video frames, the proposed approach aims to enhance cryptographic security by producing keys that provide an additional layer of protection to conventional encryption algorithms. The analysis includes an evaluation with the performance based on different key sizes and entropy evaluation.
