Abstract The ping-pong protocol offers confidential transmission of classic information without a prior key agreement. It is believed that it is quasi secure in lossless quantum channels. Serious doubts related to the analysis paradigm which has been used so far are presented in the study. The security of the protocol is reconsidered.
