Abstract

The present invention relates to a process and a system for data transmission. Authentication data and an electronic key are generated, whereby the electronic key is stored as assigned to the authentication data. At least part of the electronic key is transmitted by means of an authentication module of the central module to a communications terminal. Asynchronously to that, data are encrypted into encrypted data by means of an encryption module and by means of at least part of the electronic key. The encrypted data are transmitted between a central module and a communications terminal. The encrypted data are decrypted by means of a decryption module and by means of at least part of the electronic key.

Claims20

Dependent claims

A method for data transmission implemented by a central communications device, the method comprising:

storing, by the central communications device, a type of data, an electronic key associated with the type of data, a user defined time, and authentication data;
determining, by an availability module in the central communications device, accessibility of a communications terminal associated with a user profile;
based on the determining and the user defined time, encrypting by the central communications device data with the electronic key associated with the type of data;
transmitting, by the central communications device, encrypted data to the communications terminal;
receiving, by the central communications device, the authentication data from the communications terminal;
and
based on the received authentication data, transmitting by the central communications device the electronic key associated with the type of data to the communications terminal.
