Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G mobile network communication systems are vulnerable to false base station attacks, particularly due to non-encrypted broadcasting of system information, and centralized encryption schemes face issues with key management, single-point failures, and reliance on core network-assisted verification.
Innovation Solution
A decentralized trusted access method using blockchain technology to ensure the authenticity and integrity of system information by implementing a network-wide consensus mechanism, enabling cellular users to verify the legitimacy of base stations during initial access without relying on core network-assisted verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized encryption schemes based on core network-assisted verification are used, then system information can be protected, but single-point failure risks and reliance on centralized trust arise
Solution Approach 1:
The patent segments the centralized trust structure into distributed blockchain nodes. Instead of relying on a single core network entity for verification, the system divides trust verification across multiple decentralized nodes in the blockchain network, eliminating single-point failure risks while maintaining system information security.
Solution Approach 2:
The patent introduces blockchain as an intermediary layer between users and base stations. This intermediary provides decentralized trust verification through consensus mechanisms, replacing the traditional core network-assisted verification model and eliminating reliance on centralized trust structures.
2Reliability
If digital signature-based encryption is used, then system information can be authenticated, but key management lacks unified trust transmission in decentralized networks
Solution Approach 1:
The patent makes the blockchain network serve multiple functions simultaneously: it acts as a distributed ledger for transaction recording, a trust verification mechanism through consensus algorithms, and a key management infrastructure. This universal platform provides unified trust transmission across decentralized networks, eliminating the need for separate key management systems while maintaining authentication reliability.
3Reliability
If certificate-based encryption is used, then user terminals can verify base station legitimacy, but root certificates cannot be updated or revoked timely
Solution Approach 1:
The patent transforms the static certificate verification model into a dynamic system. Instead of fixed root certificates that cannot be updated, the blockchain network continuously updates its state through new blocks, allowing real-time revocation and updating of trust relationships. The consensus mechanism dynamically adjusts which base stations are trusted based on current network state.
4Ease of operation
If identity-based encryption with third-party key management is used, then user keys can be managed centrally, but single point of failure risk arises when the third party fails
Solution Approach 1:
The patent segments the third-party key management function across multiple decentralized blockchain nodes. Instead of relying on a single third party, key management operations are distributed across the network, with each node maintaining copies of the ledger and participating in consensus. This segmentation eliminates single points of failure while maintaining ease of operation through automated smart contract-based key management.

AI summary
The present disclosure belongs to the field of communications and more particularly relates to a decentralized trusted access method for a cellular base station. The method includes: uploading registration information to a blockchain network to add the cellular base station as a member to the blockchain network; uploading a master information block to the blockchain network, receiving block identification information from the blockchain network; broadcasting the master information block and the block identification information to cellular users within the coverage area; receiving an access request from the cellular user, and in response to the access request, performing uplink synchronization with the cellular user issuing the access request based on a random access procedure.
