Detailed Description
The following examples will enable those skilled in the art to more fully understand the present invention and are not intended to limit the same in any way.
Considering the characteristics of space-time factors, dynamic distribution and the like of driving vehicles, the problems of difficult authentication and retrieval delay exist in the storage of charge and discharge information of the same vehicle; and the mutual correlation authentication processing is lacking among each piece of data, so that the safety problem of data deletion or falsification can occur under the conditions of network delay or artificial damage and the like, and the accuracy and the credibility of the charge and discharge information are further reduced. Therefore, the invention designs the block chain for the V2G charge and discharge information.
Vehicle charge and discharge information blockchain design
As shown in fig. 1, the block chain mainly comprises a message header of the license plate in a database, a last charge and discharge information hash value, a current charge and discharge information hash value, a random number ciphertext and a timestamp ciphertext, wherein the message header comprises a current charge and discharge information identification code of the license plate, sequential codes and the license plate, the sequential codes are the numbers of a server generating a block for the current charge and discharge of the license plate, and the license plate number is added for quick retrieval and confirmation; the hash value corresponding to the charge and discharge information of the front and back times is used for determining the association relation of the vehicle storage information, so as to identify lost or tampered data; to ensure uniqueness of the blockchain, the random ciphertext includes a random number and a timestamp.
Vehicle charge and discharge information authentication design
In order to ensure the accuracy of matching of the vehicle charging and discharging information and the vehicle information in the blockchain and prevent artificial malicious theft of discharging benefits, the vehicle charging and discharging information needs to be authenticated when the vehicle is connected to a power grid every time, and the accuracy of the blockchain information is ensured.
Because the vehicle charging and discharging are in two behavior modes, the electric power grid transmits electric energy to the electric automobile during charging, and the electric automobile transmits electric energy to the electric power grid during discharging. Each automobile has different charging and discharging times in a V2G mode, the charging and discharging times of each time are bound with the automobile information and updated in real time, the reliability and the safety of the charging and discharging information can be ensured, and the occurrence of charging and discharging behaviors by embezzling the automobile information of a user is avoided.
The system authentication design mainly comprises vehicle information authentication and charge and discharge frequency authentication, and the specific discrimination flow is as follows:
the first step: the power monitoring equipment acquires vehicle information and charge and discharge times and uploads the vehicle information and the charge and discharge times to a server node;
and a second step of: the server node which receives the vehicle information and the charge and discharge frequency information for the first time searches for authentication in the whole network;
and a third step of: other nodes in the whole network analyze the database information according to the authentication requirement and match the vehicle information and the charge and discharge frequency information;
1) And (3) matching the vehicle information, and mainly verifying whether license plates, vehicle types, battery models and the like are matched with the vehicle registration information. If both are matched, the information is true; otherwise, it is false.
2) And (3) matching the charge and discharge times, and mainly verifying whether the charge times and the discharge times are consistent with the historical monitoring data. If the numbers are consistent, the times are true; otherwise, it is false.
Fourth step: the respective authentication nodes feed back the matching result to the head node, and the head node analyzes the true and false feedback result of the information, if the two types (vehicle information and charge and discharge times) of information are judged to be all true, the information is judged to be true, and the generation of the block chain information is executed; otherwise, judging that the charge and discharge information of the vehicle is in doubt, starting warning and powering off.
Note that: the default total number of vehicle charging and discharging times is stored in a vehicle end and can be read by the charging and discharging monitoring equipment.
For example, when a vehicle with a license plate A is charged for d times and is charged and discharged for c+1th or d+1th times, the charging and discharging equipment acquires vehicle information and frequency information and uploads the vehicle information and the frequency information to the whole network; searching stored data of A by other nodes in the network, wherein the frequency information is obtained by simple addition operation of an identification code in a block chain message header, and then performing matching authentication; at least one node considers the vehicle A information to be true, and judges that the information passes authentication when the information is fed back to the head node, and applies for passing; if all other node authentication information is false, judging that the information authentication is suspicious when the information authentication information is fed back to the head node, starting a warning and powering off.
The vehicle charge and discharge information blockchain design comprises the following steps:

The block mainly comprises six parts of information such as a message head, a vehicle information ciphertext, a random ciphertext, a last block hash value, a present block hash value, a next block hash value and the like.
Seventh step: the first node takes a vehicle license plate as a retrieval object, the block chain information of the license plate is retrieved at each node of the whole network, each node transmits the length and identification code sequence information of the block chain to which the license plate belongs in the node together with the node number to the first node, and the first node compares and judges feedback information of each node and selects longest chain information with accurate sequence;
if the length of the longest chain is 0, the information is the starting point of the block chain of the charging and discharging information of the vehicle, so that whether the serial number of the block is 1 is verified, and if the serial number of the block is 1, the first node is a chain generation node; if not, a warning is sent out;
if the length of the longest chain is not 0, the information is a non-starting point of the block chain of the charging and discharging information of the vehicle, so that whether the serial number of the block is N is verified, and if the serial number of the block is N, the next step is executed; if not, giving a warning;
eighth step: the head node sends the block information generated in the seventh step to a chain and generates a node;
