Extended MIKEY Protocol Key Management

The patent extends the MIKEY protocol to provide multiple key-management operations (key transport, key deletion, key activation, key update) within a single protocol framework. By adding general extension payloads and KMM structures to the existing MIKEY protocol, it becomes universally applicable to both broadband and narrowband devices, eliminating the need for separate protocol implementations.

The patent segments the key-management functionality into distinct operable types (key transport, key deletion, key activation, key update) that can be independently selected and executed. Each operation type is represented as a separate KMM with specific payload structures, allowing the protocol to handle different key-management tasks through modular, segmented operations rather than a monolithic approach.

The extended MIKEY protocol serves as a universal key-management solution that works across both broadband and narrowband devices. By incorporating general extension payloads and standardized KMM structures, the protocol maintains compatibility with existing MIKEY implementations while adding support for narrowband-specific operations, enabling cross-protocol functionality without losing key-management capabilities.

The patent introduces an intermediary layer in the form of general extension payloads and KMM structures that mediate between broadband MIKEY and narrowband key-management requirements. This intermediary mechanism allows broadband devices to execute narrowband key-management operations by translating them into extended MIKEY messages, preventing loss of key-management functionality across different device types.

The patent manages protocol complexity by segmenting key-management operations into distinct operable types, each with its own payload structure and processing logic. By dividing the extended functionality into modular operation types (key transport, key deletion, key activation, key update), the protocol avoids becoming a monolithic complex structure while still providing comprehensive key-management capabilities.

The patent introduces dynamic elements to the MIKEY protocol through the use of operable type indicators and conditional payload structures. The protocol can dynamically adapt its behavior based on the required operation type, allowing broadband devices to perform additional key-management operations while maintaining a flexible, non-rigid protocol structure that doesn't impose unnecessary complexity.
