Question: In the context of Service Enabler Architecture Layer for Verticals (SEAL), what is the basis for the functional model of key management as per the 3GPP specifications?
Option 1: It is based on a dedicated vertical-specific architecture.
Option 2: It follows a proprietary encryption standard.
Option 3: It is derived from an external, non-telecom security framework.
Option 4: It is based on the generic functional model specified for overall SEAL architecture.
Explanation: The key management functional model in SEAL is grounded in a broader, unified architectural approach (the generic functional model), ensuring consistency and integration across different aspects of the SEAL architecture, facilitating streamlined security and operational efficiency for vertical applications within the telecom domain.
