Multi-Factor Key System with Finite-State Machine

The patent divides the key identification process into multiple independent factors. Instead of using a single long key, the system uses multiple shorter keys (first key, second key, third key) where each key is associated with specific characteristics or properties. The encryption process requires satisfying multiple independent conditions simultaneously, which provides equivalent or greater security without requiring proportionally longer individual keys, thus reducing computational resource requirements.

The patent introduces additional dimensions to the key space by incorporating multiple key pairs with different characteristics rather than simply increasing the bit length of a single key. The system encrypts using a combination of keys where each key has specific properties (e.g., first key with first property, second key with second property), creating a multi-dimensional key space that provides enhanced security without linearly increasing computational complexity.

The patent incorporates a verification mechanism where the recipient receives not only the encrypted message but also additional information (first language element, second language element, third language element) that serves as feedback about the key characteristics. The recipient uses this feedback to identify which key pair was used for encryption, creating a self-guiding key selection process that reduces management complexity while maintaining high security through multiple key pairs.

The patent introduces language elements as intermediary components that mediate between the multiple key pairs and the decryption process. These language elements (first language element, second language element, third language element) act as identifiers or keys to selecting the correct key pair from the multiple available pairs, simplifying the key management process while maintaining the security benefits of using multiple key pairs.
