Inspur Communication Applies for Patent on "Key Management Method Based on Distributed Blockchain," Enhancing Information Security

On March 22, 2025, Financial World reported that the State Intellectual Property Office of China showed that Inspur Communication Information System (Tianjin) Co., Ltd. (hereinafter referred to as "Inspur Communication Tianjin") submitted a patent application for a "Key Management Method Based on Distributed Blockchain," with publication number CN119652658A and application date in January 2025. This patent application focuses on the field of information security technology, aiming to provide a more secure and efficient key management solution.

The patent abstract details the method's steps: first, the system generates a block containing key information; then, the system manages the key based on the key block, which includes three sub-steps: Step 21, querying the user's public key. Through the nodes in the blockchain network, the system traverses backward from the latest block, eventually feeding back the latest valid key to the node requesting the public key. Step 22, updating the key. This method supports key update operations to adapt to ever-changing security needs. Step 23, revoking the key. When the user's key needs to be destroyed, the system receives a key destruction request and, after the core node verifies the user's identity and authorization, destroys the key and its related information, ensuring secure key revocation.

Compared with traditional key management methods, this distributed blockchain-based key management method has significant advantages. Traditional key management methods typically rely on centralized servers, making them vulnerable to single points of failure and security attacks. The decentralized nature of blockchain technology effectively enhances the security of key management. The distributed ledger ensures the transparency and immutability of key information; any changes to the key are recorded on the blockchain, improving the auditability of key management.

Furthermore, the distributed nature of this method enhances the system's fault tolerance and availability. Even if some nodes fail, the system can still operate normally, ensuring the continuity of key management services. This high availability is crucial for critical business operations requiring continuous security protection.

The generation and management of key blocks mentioned in the patent reflect the ingenuity of the method's design. By storing key information on the blockchain, it effectively prevents the loss or leakage of key information. At the same time, the blockchain's encryption features ensure the security of key information. The clear division of steps also facilitates system development and maintenance. The public key query mechanism in Step 21, through blockchain traversal, ensures the accuracy and timeliness of the query. Steps 22 and 23 provide key update and revocation functions, respectively, meeting the dynamic needs of key management. This modular design also facilitates future expansion and improvement.
