1Reliability

If traditional wired authentication methods are used for hardware component verification, then connection reliability is improved, but device complexity and installation difficulty increase

Engineering Contradiction:

Improveconnection reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical wired connection system with an electromagnetic field-based NFC system. The baseboard management controller and hardware components communicate through near field communication using electromagnetic fields, eliminating the need for physical cable connections while maintaining authentication reliability. This substitution reduces device complexity by removing wired connection infrastructure.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If wired authentication connections are implemented, then authentication stability is improved, but ease of operation deteriorates due to physical connection requirements

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The NFC-based authentication system replaces mechanical cable connections with contactless electromagnetic communication. The baseboard management controller wirelessly authenticates hardware components through NFC signals, eliminating the need for physical plugging and unplugging of cables. This improves ease of operation while maintaining authentication stability through cryptographic verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If remote verification of hardware components is enabled, then security against component substitution attacks is improved, but device complexity increases due to additional verification infrastructure

Engineering Contradiction:

Improvesecurity against component substitutionVSAvoidverification infrastructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The hardware components contain embedded NFC modules with cryptographic authentication credentials that enable self-verification. When the baseboard management controller initiates authentication, the hardware component autonomously responds with cryptographic proofs of its identity. This self-service mechanism allows remote verification without requiring complex external verification infrastructure, as each component carries its own authentication credentials.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The NFC module serves multiple functions: it acts as both a communication interface and a cryptographic authentication credential storage. The same NFC hardware that enables wireless communication also stores the cryptographic keys and certificates needed for authentication. This multi-functionality reduces the need for separate verification infrastructure, simplifying the overall system while maintaining security.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Productivity

If on-demand authentication is implemented, then productivity is improved by enabling rapid component verification, but use of energy increases due to continuous authentication capabilities

Engineering Contradiction:

Improvecomponent verification speedVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The authentication system operates periodically or on-demand rather than continuously. The baseboard management controller initiates NFC authentication only when hardware components are installed, removed, or when security verification is required. The NFC modules remain in low-power states between authentication events, consuming minimal energy. This periodic operation enables rapid verification when needed while minimizing overall energy consumption.

Inventive Principle:

Principle #19Periodic action
