    摘要: The present invention relates to a management messages transmission method by a management center intended to a plurality of multimedia units. Each unit has a security module (SC) comprising at least one global encryption key used in relation with an encryption module. This method is characterized in that it consists of dividing the totality of the security modules allowing access to encrypted data originating from a determined provider into at least two groups (GR1, GR2), a first group of security modules having a first configuration of the security elements and a second group of security modules having a second configuration of the security elements, the first configuration being different from the second configuration.
