Abstract
A method (M) for controlling access to a production system (SIP) of a computer system not connected to an information system (SIC), includes: A) an initial phase of enrolling a user via a terminal (1) in the production system (SIP), which includes: a) providing a private encrypted key (Cph) associated with each account of the user in the production system (SIP); b) the terminal transmitting the encrypted private key (Cph) to the information system and the system (SIC) registering the encrypted private key; B) for each request to access the production system, a phase of authentication by the production system, which includes: the terminal of the user recovering a challenge (QRCb) generated by the production system, that only the encrypted key stored in the information system makes it possible to solve, the key only being capable of being obtained after the terminal has been authenticated by the information system.
