Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data transmission between applications in Near-RT RIC is implemented without security mechanisms, then system complexity is reduced and ease of operation is improved, but data security and reliability deteriorate

Engineering Contradiction:
Improvedata securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an encryption and decryption application as an intermediary component within the Near-RT RIC system. This mediator application handles key generation, data encryption, and decryption operations, isolating the security complexity from the core data transmission logic. By placing security functions in a dedicated intermediary layer, the system achieves reliable data protection while maintaining operational simplicity for application developers.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary key generation and encryption operations before data transmission occurs. The encryption application pre-generates encryption keys and establishes security parameters in advance, so that when data needs to be transmitted, the security framework is already in place. This preliminary preparation reduces the complexity of real-time security management during data transmission operations.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If encryption and decryption operations are implemented for all data transmissions, then data security is improved, but processing time and system resource consumption increase

Engineering Contradiction:
Improvedata securityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent generates encryption keys in advance through the encryption application before actual data transmission occurs. By pre-establishing security parameters and keys, the system minimizes the time required for security operations during critical data transmission moments, thus reducing the overall processing time penalty while maintaining strong security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The encryption and decryption application operates autonomously to manage its own key generation, storage, and rotation without requiring manual intervention or complex external security infrastructure. This self-service capability streamlines the security process and reduces the time overhead associated with security management, as the system handles security operations efficiently without additional external coordination delays.

Inventive Principle:
Principle #25Self-service
