A method for accessing a first secure communication session, referred to as a first session, in progress between participating communication terminals, referred to as participating terminals, by a requesting communication terminal, referred to as a requesting terminal. The access method includes: triggering an entry into the first session in progress of the requesting terminal on receipt of an acceptance from one of the participating terminals following a transmission of an access request message sent by the requesting terminal to at least one participating terminal of the first session.
