Shanghai Wanxiang Blockchain Applies for Patent on "Trustworthy Data Witnessing Method and System based on Three-Party TLS"

Financial World, November 15, 2024 - According to information released by the State Intellectual Property Office, Shanghai Wanxiang Blockchain Co., Ltd. has filed an application for a patent titled "Trustworthy Data Witnessing Method and System based on Three-Party TLS", with publication number CN118944870A, filed in July 2024.

This patent addresses the security and reliability issues in existing data witnessing technologies. The patent abstract states that the invention utilizes the Three-Party TLS protocol to achieve enhanced integrity and trustworthiness of the data witnessing process through a secure handshake between the witnessing service end, the user end, and the trusted data source end.

Specifically, the method includes the following steps:

1. Handshake Stage: The witnessing service end and the user end exchange public keys with the trusted data source end, respectively, and use their private keys to calculate session key fragments.

2. Encrypted Request: The witnessing service end and the user end collaboratively compute the encryption of the user's plain text request information using their respective session key fragments and send the encrypted request to the trusted data source end.

3. Decrypted Response: The user end receives the encrypted response from the trusted data source end and collaboratively computes the decryption of the encrypted response with the witnessing service end to obtain the plain text information of the response.

4. Proof Generation: The witnessing service end uses the original encrypted response and relevant session data as proof, and signs the proof using its private key to form a valid proof of the plain text response.

The method proposed in this patent effectively enhances the security and reliability of the data witnessing process by introducing the Three-Party TLS protocol and employing key fragmentation and secure collaborative computation technologies. The patent is expected to be widely applied in blockchain, IoT, cloud computing and other fields, providing more secure and reliable data witnessing services for users.

This patent showcases the technological innovation of Shanghai Wanxiang Blockchain in the field of data security and offers a new direction for promoting the development of blockchain technology applications. In the future, as blockchain technology continues to evolve, data witnessing technology will also continue to evolve, providing strong support for building a more secure and reliable digital economic system.
