A method for generating a one way transmission and keyless decoding of information, comprising: generating keyless coded information at a sender, said keyless coded information comprising an index, a challenge, and a response from a predefined challenge and response table stored in a computer memory at said sender, said keyless coded information comprising a complete self-authenticating message that when received by an authorized receiver does not require a response from said receiver to said sender; receiving said keyless coded information at said authorized receiver, said predefined challenge and response table also stored in a computer memory at said authorized receiver; comparing, with a processor at said authorized receiver, said challenge and said response at said index in said predefined challenge and response table; upon determining that said challenge and said response are correct, determining a first decoded answer; and upon determining that either said challenge or said response, or both are incorrect, determining a second decoded answer.
