Abstract (en)

[origin: FR2841070A1] The method includes the steps of reception of a code entered by a user on an interface device (4a-c), transmission of a first read request from the interface device to a first server device (3), in which are stored the respective personal cryptographic data for a number of users encoded by using a respective authentic code for the user. The next step includes reception of the encoded personal cryptographic data for the user in the interface device, decoding the personal cryptographic data by the entered code when the entered code corresponds to the authentic code for the user, and finally use of the personal cryptographic data to secure an exchange of contents data between the interface device and one second server device (2a-b) and erasure of the entered code and the personal cryptographic data from the interface device.
