Encryption scheme using Mealy Machine

This novel encryption scheme leverages a Mealy machine for dynamic encryption. To significantly enhance data security, it enforces strong key requirements (with mixed uppercase letters, digits, and special characters). The encryption process involves pre-processing data, creating a character mapping matrix, integrating a Mealy machine based on the matrix sum for additional complexity, generating and validating a strong key, and manipulating the data with the key matrix and Mealy machine outputs. Decryption follows a similar approach to recover the original data, making the system efficient for both encryption and decryption. This work paves the way for a secure and versatile encryption solution.
