The embodiment of the present application provides a data synchronization verification method, system, computing device and storage medium. In the embodiment of the present application, within a predetermined time, the operating frame rate of the client installed in the terminal is greater than the operating frame rate of the server within a preset range, receives the first frame data packet, executes the first operation instruction, and obtains the first operation result; stores the correspondence between the first operation result and the first frame packet identifier to the corresponding cache queue; sends the first operation result to the corresponding multiple terminals through a frame message packet, and the frame message packet carries a second frame packet identifier corresponding to the first frame packet identifier. Thereby, after receiving the frame message packet, the terminal returns the second operation instruction and the frame packet identifier corresponding to the operation result before the second operation instruction through the second frame data packet to verify the second operation instruction. Thereby, the operation result can be verified more accurately for state synchronization.

This invention discloses an end-to-end verification method, system, and product for video streams based on Schnorr signatures. The sending end first encodes the audio and video streams into a continuous sequence. For each encoded transmission packet, a point in the group is calculated using random numbers as the random commitment point for the frame signature, where is the generator of the selected elliptic curve group, and the group order is a prime number. Then, a signature scalar is calculated according to the Schnorr signature algorithm. Next, the original video frame data, the random point, and the signature scalar are combined into an authentication data packet, which is pushed to the server and client in real time via a network protocol. Finally, the client performs instant authentication and cache management, while the server performs frame-by-frame verification and aggregated storage. This invention utilizes the linear aggregation characteristics of Schnorr signatures to achieve efficient authentication and traceability of real-time video streams and historical stored data while significantly reducing storage space requirements, ensuring the integrity and evidentiary value of the video data.

The invention discloses a non-interactive instant identity authentication and secure data transmission method, which comprises the following steps of: generating global parameters through a trust mechanism, distributing the global parameters to an edge terminal, an authentication center and an edge computing server, and performing edge terminal authentication by adopting a non-interactive identity authentication technology. And the edge terminal generates and sends an instant authentication certificate in the authentication process to realize secure connection with the edge computing server. The security of communication is ensured by adopting a hash function and a public key cryptography technology, and an illegal terminal is prevented from accessing the system through a non-member certification and revocation list mechanism. The edge terminal and the server are encrypted through a temporary symmetric key, so that the confidentiality and integrity of data transmission are ensured. The method has the advantages of efficient identity authentication, reliable data transmission security and optimized calculation and bandwidth utilization, is suitable for edge calculation scenes with limited resources, and has good security, efficiency and expandability.
