METHOD OF AUTHENTICATION, WITH ESTABLISHMENT OF A SAFE CHANNEL, BETWEEN A SUBSCRIBER AND AN ACCOUNTANT SERVICE PROVIDER THROUGH A TELECOMMUNICATION OPERATOR

摘要

The system includes an initial inscription process, followed by an exchange of authentication data The process provides authentication of a subscriber and establishment of a secure connection channel between a subscriber and a service provider. It includes an initial inscription process when the subscriber communicates with the service provider via the operator. The process includes an exchange of authentication data (DeviceID, R1; login, mdp) on line and off line. The encoded channel is eventually established at the start of each session, after mutual authentication, which also uses cryptographic functions. Finally an encoding key (Kses) is established without transmission of a secret element on the network(s).
