China Mobile Research Institute Files Patent for Blockchain Key Update, Potentially Boosting Mobile Communication Security

Financial World, August 28, 2024 - According to Tianyancha's intellectual property information, China Mobile Communications Corporation Research Institute and China Mobile Communications Group Co., Ltd. have filed a patent for a "Blockchain Key Update Method, Blockchain Node and Readable Storage Medium," with publication number CN202310188583.4, filed in February 2023.

This patent aims to address the security risks and low efficiency of existing blockchain key update methods. It proposes a new key update method that effectively enhances the security and efficiency of blockchain networks. The patent abstract reveals the following steps involved in this method:

1. Generating Values: Generate three values: the first value, the second value, and the third value. The third value is derived from the first function and the second value, while the second value is derived from the second function and the first value.

2. Sending the First Transaction Request: Send a transaction request containing the first transaction and signature. The first transaction includes the third value and the original public key, and the signature is generated using the original private key.

3. Generating New Keys: Generate new public and private keys.

4. Encrypting New Keys: Encrypt the new public key and the second value using the new private key, resulting in ciphertext.

5. Sending the Second Transaction Request: Send a transaction request containing the second transaction and signature. The second transaction includes the identifier of the first transaction, the original public key, and the ciphertext, and the signature is generated using the original private key.

6. Sending the Third Transaction Request: Send a transaction request containing the third transaction and signature. The third transaction includes the identifier of the second transaction, the new public key, and the first value, and the signature is generated using the new private key.

This patent decomposes the key update process into multiple transaction requests and employs complex mathematical operations and encryption techniques to ensure the security and efficiency of the update process. Additionally, the method introduces a readable storage medium for storing and managing relevant information during the key update process, further enhancing security.

This patent application demonstrates China Mobile's proactive exploration of blockchain technology applications in the telecommunications field and its commitment to enhancing the security of mobile communication networks. As this patented technology further develops and gains traction, it will significantly impact the mobile communication security sector, providing users with more secure and reliable communication services.

Potential Application Scenarios for this Patented Technology:

• 5G Network Security: This technology can be utilized to update user keys within 5G networks and protect sensitive data, enhancing 5G network security.

• Internet of Things (IoT) Security: The technology can be applied to key updates for IoT devices, effectively improving their security and privacy protection.

• Mobile Payment Security: This technology can be used to update keys on mobile payment platforms, enhancing mobile payment security and preventing financial losses for users.

Summary:

This blockchain key update patent filed by China Mobile Research Institute signifies its active exploration and innovation in blockchain technology, underscoring its emphasis on mobile communication security. The application of this patented technology will effectively enhance the security and efficiency of mobile communication networks, providing users with more secure and reliable communication services. With the advancement and widespread adoption of blockchain technology, this technology is poised to play a vital role in various fields, driving significant progress in the mobile communication industry.
