Abstract
A method of keyless encryption of messages allows secure transmission of data where data security is not available for some technical or legal reason. The method of data transfer uses a challenge response in which a correct response to a challenge is used to transmit the value “1”, while a deliberately false response is made to transmit the value “0”. Any message can be transmitted as a binary string using successive applications of this method.
