The road side unit receives the identity information sent by the first vehicle terminal, generates a first vehicle terminal private key and a first vehicle terminal public key, sends the first vehicle terminal private key to the first vehicle terminal, and sends the first vehicle terminal public key to other nodes of the block chain according to requirements.
After the first vehicle terminal generates the vehicle sharing information, a HASH (HASH) value of the vehicle sharing information is obtained through HASH operation, then the vehicle sharing information is signed by using a private key of the first vehicle terminal, a vehicle sharing signature is generated, and the vehicle signature sharing information is constructed according to the vehicle sharing signature. The vehicle signature shared information includes vehicle shared information and a vehicle shared signature. And the first vehicle terminal sends the vehicle signature sharing information to the road side unit.
The road side unit receives the vehicle signature sharing information and generates road side sharing information according to the vehicle signature sharing information. Specifically, the road side unit receives the vehicle signature shared information, acquires a road side unit identifier, and generates road side shared information according to the road side unit identifier and the vehicle shared information.

The platform number threshold may be preset according to the sum of the number of other platforms. In one embodiment, the preset threshold value of the number of the platforms is 51% of the sum of the number of the other platforms, the number of the other platforms with consistent results is counted, and if the counted number exceeds 51% of the sum of the number of the other platforms, the platform sharing information is marked as platform sharing information passing the verification; if the counted number does not exceed 51% of the sum of the number of other platforms, the platform sharing information is marked as the platform sharing information which is not verified. The verification refers to a majority consensus algorithm verification of the platform.
In one embodiment, the first platform and the other platforms together construct a shared information recording block, which is a data structure containing data information such as platform sharing information, recording time, and block location. When any platform sharing information is marked as verified platform sharing information, the first platform obtains the recording right of the sharing information recording block, the first platform writes the platform sharing information marked as verified into the sharing information recording block, and the writing time is the recording time. The shared information blocks are linked into a shared information block chain according to the sequence of the recording time. And the first platform and the other platforms are nodes of the block chain.
