name: GDK
full_form: Group Data Key
context: A group symmetric key GDK (Group Data Key) associated with the group is used for end to end protection of group SDS messages. GDK is distributed in advance by the GMS thanks to the group key distribution as described in clause 5.2.6 of 33.179 [3]. The identifier of the group key (GDK-ID) is provided in every SDS message sent to the group.
description: A Group Data Key (GDK) is a symmetric key used for end-to-end protection of group SDS messages. It is distributed by the GMS using group key distribution and identified by a GDK-ID.
explanation: The context explicitly describes GDK as a key associated with a group, used for protecting group SDS messages, which aligns with the definition of a Parameter in the telecommunications domain.
