Abstract

Embodiments of the present disclosure disclose a data authentication method, a data authentication apparatus, and a data authentication system. An embodiment of the data authentication method comprises: in response to receiving an authentication request submitted to authentication nodes in an authentication system for authenticating that a vehicle passes self-driving scene testing, verifying the authentication request, the authentication request containing simulation data regarding self-driving testing of the vehicle in a simulated driving scene and authentication award information; in the case of passing the verifying, generating an award record for an authentication node that completes verification first based on the authentication award information, and writing a verification result and the award record into a distributed data block chain corresponding to the authentication system. The embodiment realizes authentication to the driverless vehicle simulation testing data, which may ensure reliability of the authentication result while reducing the time and cost consumed for the authentication.

the verifying the deciphered simulation data comprises:

recording the deciphered simulation data, and monitoring whether a recording result issued from other authentication node(s) has been received before the recording is successful;

if the recording is successful before receiving the recording result issued from the other authentication node(s), broadcasting the recording result to one or more other authentication node(s) such that the one or more other authentication node(s) receiving the recording result checks the recording result according to a preset check rule;

if the recording is unsuccessful before receiving the recording result issued from the other authentication node(s), checking the received recording result according to the preset check rule; and

in response to a number of authentication nodes where the checking passes satisfying a first preset condition, determining that the deciphered simulation data passes the verifying, and generating a verification result based on the recording result recorded for the deciphered simulation data.

4. The method according to claim 3 , wherein the recording the deciphered simulation data comprises:

combining the simulation log and data already stored in the data block chain to form a record list, and executing an authentication operation below: performing a Hash operation based on a random number and the record list, and determining whether a Hash operation result satisfies a preset target value;

if so, determining that the simulation log is successfully recorded, and generating a respective recording result containing the random number and the simulation data; and

if not, changing the random number, and performing the authentication operation.

5. The method according to claim 2 , wherein the simulation data includes a binary simulation file; and wherein
