name: DPPK
full_form: MCData Payload Protection Key
context: between two offline clients are protected using a PCK (e.g. the DPPK is the PCK). - MCData signalling payloads between a group of offline clients are protected using a GMK (e.g. the DPPK is the GMK). MCData data payloads are protected as follows: - MCData data payloads end-to-end protected between two online clients are protected using a PCK (e.g. the DPPK is the PCK). - MCData data payloads end-to-end protected between two offline clients are protected using a PCK (e.g. the DPPK is the PCK). - MCData data payloads end-to-end protected between a group of online clients are protected using a GMK distributed by a GMS (e.g. the DPPK is the GMK). - MCData data payloads end-to-end protected between a group of offline clients are protected using a GMK distributed by a GMS (e.g. the DPPK is the GMK). NOTE: The DPPK is not a new type of key, it describes how the MC system's existing key types are used to protect MCData. Consequently, there will be multiple DPPKs in the MC System depending on
description: The DPPK (MCData Payload Protection Key) is a parameter that describes how the MC system's existing key types are used to protect MCData payloads. It is not a new type of key but rather a way to utilize existing keys for protection.
explanation: Based on the context from 3GPP TS 33.880, section 7.5.5.3, DPPK is classified as a Parameter because it refers to a specific attribute or setting within the MC system that governs how data payloads are protected using existing key types.
