differential & linear cryptanalysis of heys cipher

A neural network-based encryption system built with TensorFlow and Keras. It securely transforms plaintext into ciphertext and back, providing strong protection against cryptanalysis and adversarial attacks. Scalable for real-time communication and cloud storage.
