Method and system for encrypted data transmission

摘要

The method involves generating authentication data (A) and an electronic key (S), where the electronic key of the authentication data is assigned stored. Data (D) is coded by a coding module of a central module (10) and by a part of the electronic key. One communication terminal (mPh) selects another communication terminals (hC,mC,oC).The coded data (vD) are transmitted by the transmission module of the central module based on the identification of the selected another communication terminal to the other communication terminal. A part of the electronic key is transmitted to the communication terminal on the basis of a transmission of authentication data between three communication terminals and an authentication module of the central module. The coded data is decoded by a decoding module of the other communication terminal and by a part of the electronic key. An independent claim is also included for selectable data transmission system.
