The invention relates to a method for secure communications in a telecommunications network, said network comprising a group of servers S(where i=1, 2, . . . , p, and p is a strictly positive integer), referred to as Authorization Servers. For a transaction between an entity A and an entity B of said network, this method comprises the following steps: a) entity A sends to one of the Authorization Servers San authorization request in which the entity A identifies and authenticates itself as the holder of an identifier ID; b) the entity A declares to said Authorization Server Sits intention to communicate with the entity B and the Authorization Server Sdetermines an individual secret key Kwhich it shares with this entity B; c) the Authorization Server Sgenerates a session key Kand sends said session key Kto the entity A; d) the Authorization Server Sgenerates a transaction identifier IDTR; e) the authorization server Ssupplies the entity B with elements comprising at least said transaction identifier IDTR; f) using this transaction identifier IDTR, the entity B checks the validity of the transaction, and g) the entity B generates the session key K. 1.
