<p>The method involves generating of random message keys just once to use within the transmission unit (1), coding of the message (11,12,13,14) by means of the message keys within the transmitter to the first coded quantity of data. Method also involves coding of the message keys with the public keys of the receiver unit (2) as well as a service generating device (3) for second coded quantity of data. The method then involves digital signing of the hash values of the first and second coded data set with in the transmitter, sending message from transmitter to receiver, examining of dual signature, sending of the sending message, examining of dual signature in service generating device. The method then involves decoding of second coded data set to third coded data set, sending of third message to receiver, decoding of third coded data set, sending of the fourth message, examining of dual signature received from service generating device and holding of written messages, key and the fourth quantity of data as a confirmation receipt in the transmitter.</p> |
