Abstract: A method for initiating a secure session using a smartphone as a physical token to provide strong authentication. The phone is used through a public and independent real-time notification service. The notifications are exchanged in an encrypted manner so that their content is only accessible to the mobile phone and the authentication server.

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.

Abstract: A method for changing the status, locked or unlocked, of a target machine including a security service and a session management module includes receiving, by the security service, a query corresponding to a request to change the status of the target machine, the query including at least one piece of identification information from a user of a source machine; from the security service, verifying if access rights to the target machine related to the user of the source machine allow a change in the status of the target machine by the user; if so, sending, from the security service, a status change message to the session management module of the target machine and proceeding to the status change made by the session management module.

Abstract: A method for propagating session management events between a plurality of machines forming a machine cluster includes generating, with a session management user interface, a session management event on a first machine of the machine cluster; detecting, with an installment of the interface, the generated event; sending, from the installment to a first security service related to the first machine, a set of specific information that is related to the detected event; determining, with the first security service, a set of target machines; sending the specific information from the first security service to target security services that are related to the target machines; and processing the specific information at each target security service of the target machines so as to execute, on each target machine that has received the specific information, the session management event generated on the first machine.
