A recursive based approach to key generation produces keys for encrypted communication. Simple mathematical operations are utilized with the inherent uncertainty of an interactive process between two endpoints to establish a common secret key. The uncertainty-based key cipher starts with some public information and some private information. The public information includes a vocabulary (alphabet) and keypad, and the private information can include an authentication code. The keypad is an abstraction that represents, for example, a set of buttons. These buttons will be used to translate a working key into a text that could be used to evaluate coincidences in a generated working key. Each keypad button can have more than one possible value. The number of options inside the button is the so called uncertainty level.
