Abstract
This paper presents a conceptual framework for a multi-layer cipher system that combines rotational substitution, alphanumeric transformation, situational signaling, reverse encoding, and adaptive key management. The proposed system originates from an exploratory study aimed at understanding how multiple simple encoding mechanisms can be combined to produce a more structured communication security framework. The framework consists of four principal components: (1) letter encryption and decryption using rotational keys, (2) numerical encryption with adaptive representations, (3) situational cipher symbols for communicating predefined conditions, and (4) key scheduling and rotation strategies including alternate key families and secret constants. The study does not claim cryptographic equivalence with modern standards such as AES or RSA. Instead, it proposes an experimental architecture for secure communication research and educational investigation. The framework is intended to stimulate discussion, criticism, and further analysis by researchers interested in classical and hybrid cryptographic approaches.
