Abstract: Two parties will engage in encrypted data communicating over a non secure channel. The encryption require a common session or consecutively updated key, not known by anybody else, and established without prior secrets. One of the parties, the initial sender, creates a table of multiple equations. Each equation contains parameters, known only by him, variables set to different values for different equations, and a solution. Each equation is true. He sends the information to the initial receiver who uses the original equations to form multiple new ones, thereby obfuscating their origin. The initial receiver keeps the solution side secret and return only the variable parts of his new equations. The initial sender receives the new equations and uses his hidden parameters to calculate the solutions. The solutions will now be known by the two communicating parties, but not easily available for an unauthorized interceptor of the communication.
