1. A pairing management method between a security module and a user unit, the latter having bi-directional communication means with an operating centre, characterised in that it consists in:

  • detecting by the user unit if the connected security module is paired with it, if it is so, using a unique pairing key specific to the couple user unit/security module to encrypt the exchanged data, if it is not so, requesting the operating centre the authorisation to pair with this security module, this request being accompanied by the identifications of the user unit and the security module, verifying by the operating centre the conformity of this pairing request and transmitting the result to the user unit, if the authorisation is given, establishing a pairing key unique to the couple user unit/security module to encrypt the exchanged data.
