CENTRALIZED KEY MANAGEMENT IN EMBMS

Document Type and Number:

WIPO Patent Application WO/2013/164803

Kind Code:

A1

Abstract:

A split architecture eMBMS with distributed BMSCs providing the same eMBMS service allows for a centralized key service where each BMSC is able to derive a set of MTKs from the MSK using the MTK-IDs as the differentiating input. This avoids the need to send MTKs to the BMSCs.
