SYSTEM, TERMINAL, METHOD, AND SOFTWARE FOR COMMUNICATING MESSAGES

摘要

A system for secure communication of a message from a first terminal to a second terminal being operatively coupled by means of a communication network comprising an authenticating station for obtaining a random seed and for obtaining a masked seed by applying a masking function to the seed by encrypting the message using the masked seed for transmitting the seed and the encrypted message to the authenticating station; the authenticating station comprising further means for obtaining a further random seed for receiving the seed and the encrypted message for recovering the further masked seed by applying the masking function to the seed by decrypting the encrypted message using the recovered masked seed and by applying a masking function to the further seed by encrypting the recovered message using the further masked seed for transmitting the further seed and the further encrypted message to the second terminal; the second terminal comprising receiving means for receiving the further seed and the further encrypted message for recovering the further masked seed by applying the masking function to the further seed by decrypting the further encrypted message using the recovered further masked seed.
