H(e)NB Secure Data Transmission via IPsec and TLS Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insecure data transmission between Home Node-B (HNB) and Home Node-B Management System (HMS) or Home evolved Node-B (HeNB) and HeNB Management System (HeMS) poses threats due to lack of verification of configuration data and software updates, leading to potential deceptive software updates and attacks.
Innovation Solution
Implementing a secure data transmission method using IPsec and TLS tunnels to verify the integrity and confidentiality of data between HNB/HNB and HMS or HeNB/HeMS, discarding or retaining data if verification fails, and reporting errors to relevant network elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is transmitted between HNB and HMS or HeNB and HeMS via broadband IP backhaul, then connectivity and accessibility are improved, but security and reliability deteriorate due to lack of verification
Solution Approach 1:
The patent applies preliminary action by establishing secure channels and verification mechanisms before data transmission occurs. The system performs mutual authentication between HNB and HMS/HeNB-HeMS before allowing data exchange, and verifies data integrity before processing, thereby preventing security breaches while maintaining connectivity.
Solution Approach 2:
The patent introduces an intermediary security verification mechanism between the HNB/H(e)NB and HMS/HeMS. This intermediary layer includes authentication modules and data verification components that mediate all data transmissions, ensuring security without disrupting the existing broadband IP backhaul connectivity.
2Ease of operation
If configuration data and software updates are downloaded without authentication, then ease of operation is improved, but harmful factors increase due to deceptive updates and attacks
Solution Approach 1:
The patent implements preliminary authentication and integrity verification before allowing configuration data and software updates to be downloaded and installed. The system verifies digital signatures and authentication tokens prior to data reception, preventing deceptive software updates while maintaining simple download operations.
Solution Approach 2:
The patent converts the potential harm of unverified data downloads into a benefit by implementing automatic verification mechanisms that detect and block malicious data while allowing legitimate updates to pass through seamlessly, thus protecting against attacks without complicating the update process.
3Reliability
If data verification is implemented, then security is improved, but device complexity increases due to additional verification mechanisms
Solution Approach 1:
The patent applies universality by designing verification mechanisms that serve multiple functions: authentication, integrity checking, and security verification are integrated into existing HNB and HMS/HeNB-HeMS components. The same verification framework handles different data types (configuration data, software updates, signaling messages), reducing overall system complexity despite enhanced security.

AI summary
A method for secure data transmission, and the method includes: after a Home (evolved) Node-B (H(e)NB) establishes a connection with a H(e)NB Management System (H(e)MS), data is transmitted between the H(e)NB and the H(e)MS via a secure path; when the H(e)NB or the H(e)MS receives data, verify the integrity and/or the confidentiality of said received data, and if the verification fails, retain or discard said received data. The present invention also provides user network equipment and a user network equipment management system for secure data transmission. The present invention removes various threats caused by the insecure data transmission and a variety of inconveniences caused by improperly handling downloaded data of the H(e)NB in practical applications.
