Secure Consumption Data Module Authorization via Segmented Keys

The patent segments the authorization system by providing different keys (first key, second key, third key) for different software authorizations (first, second, third authorizations). Each key is associated with specific operational permissions, allowing fine-grained security control without requiring a single complex authorization mechanism. This segmentation resolves the contradiction by making the security system modular and manageable through distinct key-authoriation pairs.

The patent implements dynamic key selection based on the required authorization level. The consumption data module selectively uses different keys depending on the operation being performed - using stronger encryption and more keys only when necessary (e.g., for metrological property protection) and simpler mechanisms for routine operations. This dynamic approach maintains data security while minimizing energy consumption by avoiding unnecessary cryptographic overhead for all operations.

The patent segments maintenance tasks by authorization level. Each key and authorization pair can be independently managed, updated, or revoked without affecting other parts of the system. For example, the first key and first authorization can be maintained separately from the second key and second authorization, allowing targeted maintenance actions. This segmentation reduces overall maintenance intensity by enabling modular updates rather than requiring system-wide maintenance for any single key management change.

The patent applies the principle of local quality by granting write permissions locally and selectively through specific authorizations rather than universally. The second key and second authorization provide write permissions for changing metrological properties, but this capability is localized to authorized entities only. Different parts of the system have different permission levels - some components have read-only access while others have controlled write access. This localized permission structure enables operational flexibility where needed while maintaining security by restricting write capabilities to specific, authorized contexts.
