Abstract
A system is disclosed for securely communicating between a user device and a target device, which includes a user input receiving user inputs and a user device memory for storing at least one fixed dataset having a plurality of data bits and an inherent entropy. At least one predetermined harvest process is stored in ser device memory, which is operable within a main harvest process to distill the dataset to a predetermined bit length to define a private key of the user at a predetermined key length. A processor operates to execute the main harvest process to receive a unique user Personal Information Number (PIN) acquired by the user and having a plurality of digits associated therewith, and wherein the at least one predetermined harvest process is dependent on the user PIN and the value of at least one of the digits therein, such that the at least one predetermined harvest process is parameterized by the value of the at least one of the digits and operates differently for each value of the at least one of the digits. The processor applies the at least one predetermined harvest process to the dataset to distill the dataset down to the predetermined key length to define the private…
