Shandong Research and Development Financial Technology Research Institute Applies for Patent on "Attribute- and Reputation-Based IoT Access Control" to Enhance Security and Fairness

On January 22, 2025, the State Intellectual Property Office of China (SIPO) disclosed that Shandong Research and Development Financial Technology Research Institute Co., Ltd. submitted a patent application titled "A Method for IoT Access Control Based on Attributes and Reputation Using Smart Contracts," with publication number CN119276548A and application date in September 2024. This patent aims to revolutionize IoT access control by combining smart contracts, attributes, and reputation mechanisms, thereby improving security, fairness, and efficiency. The core of this innovative technology lies in leveraging blockchain technology and smart contracts to achieve granular and traceable access management of IoT resources.

Detailed Explanation of the Patent Technology: A Method for IoT Access Control Based on Attributes and Reputation

The patent application discloses a novel IoT access control method, the core process of which can be summarized in the following steps:

Step 1: IoT Information Registration

First, IoT devices and users need to register on the blockchain, recording relevant information. This step ensures the authenticity of all participating parties and the reliability of information, laying the foundation for subsequent access control. Registered information will be securely stored on the blockchain, forming an immutable record, achieving data transparency and traceability.

Step 2: Information Recording and Return

After completing the registration, the blockchain system feeds back the registered information to the IoT device and permanently records the relevant information on the blockchain. This step ensures the consistency and integrity of the information, avoiding the risk of information loss or tampering. The decentralized nature of blockchain technology guarantees the reliability and security of information, effectively avoiding single points of failure and data centralization risks.

Step 3: Smart Contract Condition Judgment

Users can interact with the blockchain and use smart contracts to determine whether their access requests meet the preset conditions. Smart contracts, as automatically executed program codes, automatically verify user access permissions based on predefined rules. This greatly improves the efficiency and automation of access control, reducing the risks and delays caused by manual intervention.

Step 4: Blockchain Information and Reputation Value Update

Based on the judgment results of the smart contract, the blockchain will automatically update the user's information and reputation value on the chain. If the user's access request is legitimate, their reputation value may be improved; otherwise, they may be penalized, such as a reduction in reputation value or restricted access permissions. This dynamic reputation assessment mechanism encourages users to comply with the rules and maintain the security and stability of the IoT system.

Step 5: Verification of the Reasonableness and Correctness of Access Control

Before each access request, the system rigorously verifies the user's access permissions to ensure the reasonableness and correctness of access. The smart contract automatically compares the user's attributes, reputation value, and access requests, ensuring that only eligible users can access the corresponding resources. This effectively prevents unauthorized access and data breaches.

Step 6: Permission Update and Full Traceability of Resources

By dynamically updating the user's reputation value attributes, the system can flexibly adjust the user's access control permissions. This dynamic adjustment mechanism can adapt to the ever-changing IoT environment, ensuring that the access control strategy remains effective. At the same time, the entire access process is recorded on the blockchain, achieving full traceability of resource access, facilitating traceability and auditing.

Advantages and Significance of the Patent Technology

This IoT access control method based on smart contracts, attributes, and reputation has significant advantages over traditional access control methods:

• Full Traceability: Utilizing blockchain technology, it achieves full traceability of IoT resource access, facilitating traceability and auditing, and improving transparency and accountability.

• Decentralized: Employing distributed ledger technology, it avoids single points of failure, enhancing system robustness and reliability.

• Granular Control: Attribute- and reputation-based permission management allows for granular control of IoT resources, meeting the different needs of different users.

• Reduced Communication Overhead: The automated execution of smart contracts reduces manual intervention, lowering communication overhead and improving system efficiency.

• Enhanced Security and Fairness: By incorporating reputation mechanisms, it effectively improves the security and fairness of IoT access control, preventing malicious attacks and resource abuse.
