Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The terms "comprises" and "comprising," and any variations thereof, in the present description and claims and drawings are intended to cover a non-exclusive inclusion, such as a list of steps or elements.
The technical solution of the present invention is further described in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1, a charging method for an electric vehicle charging pile device includes: acquiring charging information, wherein the charging information comprises a fixed character interference string FixStr, an IDCustId of an enterprise to which equipment belongs, an IDDevId of charging pile equipment, a HuId of an automobile owner, effective time ExpTime of a two-dimensional code, charging hours, a ChargeHour and an equipment secret key TermKey, and the equipment secret key is stored in a cloud end and an equipment end at the same time;
generating a cloud deduction code according to the charging information;
generating a two-dimensional code deduction bill according to the charging information and the cloud deduction code, wherein the two-dimensional code deduction bill does not contain the equipment key TermKey;
the cloud deduction code is sent to a vehicle owner through a cloud end, the vehicle owner shows the cloud deduction code, and charging pile equipment of the battery vehicle reads the cloud deduction code to obtain read charging information;
combining the read charging information with the equipment key TermKey and the fixed character interference string FixStr, and obtaining a local deduction code according to an abstract algorithm the same as that of the cloud;
and the terminal compares the cloud deduction code with the local deduction code, if the comparison is passed, the charging device is started, otherwise, the verification is not passed, and the charging is refused.
As shown in fig. 2, generating the cloud deduction code according to the charging information specifically includes:
in order, splicing
FixStr + CustId + DevId + HuId + ExpTime + ChargeHour to obtain a long character string LongStr;
extracting fingerprint information from all data by adopting a data abstract algorithm to realize the functions of data signature and data integrity verification, and requiring irreversibility;
after more than 10000 times of blasting tests are carried out on the two-dimensional code deduction data on site, the best two data summarization algorithms are selected, namely Md5 and SHA 1.
And adopting a data summarization algorithm to the long character string LongStr to obtain a summarized value HashStr.
Since the algorithm for generating the abstract consumes cpu, the data abstract is selected once according to the actual performance of the terminal equipment, LongStr + TermKey is spliced, and the safety of the algorithm is slightly reduced when the abstract is implemented once on the whole data.
In practical application, primary or secondary data summarization is selected according to the performance of equipment.
Splicing the HashStr + TermKey again, and obtaining a second abstract value by adopting a data abstract algorithm, wherein the second abstract value is the cloud deduction code PayCode.
The core point of the invention lies in an off-line verification mechanism of the two-dimension code, namely, the cloud end generates a data summary for the business plaintext data and the secret key data by using an irreversible data summary algorithm, the equipment terminal also generates a data summary by using the same algorithm, and then the cloud end summary and the terminal summary are compared to realize the off-line verification mechanism.
The above verification mechanism needs other mechanisms to help to ensure the security of the whole authentication to the maximum, and includes the following mechanisms or methods, as shown in fig. 3:
a terminal key filling and updating mechanism:
the length of the secret key is 32 bits long, the first 16 bits and the second 16 bits are generated by different people and input into the cloud terminal and the entrance guard terminal equipment at the same time, and after the input of 2 people is completed, the manual filling of the initial secret key is completed.
And (4) placing the terminal equipment in a network environment, and starting a secret key updating mechanism.
The cloud randomly generates a 32-bit temporary secret key, 3DES encryption is carried out on the temporary secret key by using an initial secret key to generate a ciphertext and a check code, the ciphertext and the check code are sent to an equipment end in a certain communication mode, such as Bluetooth, after the equipment end successfully verifies the initial secret key, the ciphertext of the temporary secret key is decrypted, then the initial secret key is replaced by the temporary secret key, and the secret key updating of the equipment end is completed; and after the cloud end receives a response that the equipment-side secret key is successfully updated, the cloud end immediately starts the temporary secret key, and the cloud end finishes the secret key updating.
Since the updating process is not manually participated, the risk of the key being leaked is extremely low.
To further increase security, it is stipulated from regulatory aspects that keys must be updated regularly.
The clock synchronization mechanism of the equipment terminal comprises the following steps:
in order to reduce potential risk loss, the validity period of the two-dimensional code by the equipment needs to be judged, and the two-dimensional code is recommended not to exceed 24 hours, namely, if the deduction bill is not used, the deduction bill is invalidated after 24 hours.
The equipment needs to verify the validity period of the two-dimensional code, the clock and the cloud end of the equipment end need to be ensured to be synchronous, and the time error cannot exceed 5 minutes.
It may be administratively specified that the clock synchronization is done once per month for the devices.
The clock synchronization request is initiated by a mobile phone with a correct clock and is sent to the equipment end through a certain communication mode (such as Bluetooth), and the equipment end updates the local clock.
Mechanism to prevent one code from multiple use:
in order to prevent the same two-dimensional code from being used for multiple times in the validity period, a Paycode queue is established locally by the equipment terminal.
The length of the queue is determined according to the maximum charging times in the validity period of the two-dimensional code, for example, the validity period of the two-dimensional code is set to 24 hours, the maximum charging times in 24 hours is 1000 times, and the length of the queue can be set to 2000.
And inserting the PayCode into the head of the local queue after the two-dimension code verification is successful each time.
Before verification, the PayCode queue is searched, if the same code exists, the code is regarded as a code with multiple purposes, and the verification fails.
Post check mechanism:
the reconciliation mechanism is not necessary and depends on the risk management requirements of each enterprise.
In order to finally reduce the possible risks in security technology or key management, the charging records of the equipment and the two-dimensional code bill generated by the cloud end can be checked at irregular intervals.
Each device can store a certain number of charging records, the maximum number of records is determined by referring to the device performance and the actual charging records, and the device is suggested to be designed to store 5 ten thousand records.
The manager can connect the device through a communication mode (such as Bluetooth) by adopting the mobile phone at irregular intervals, and the charging record is imported from the device and stored in the mobile phone offline.
And the two-dimensional code deduction bills uploaded to the cloud end and the cloud end system by the mobile phone are checked one by one in a networking environment.
And for the failed verification, immediately updating the equipment key, checking the problem and finding a bug, and reducing the loss to the minimum.
Has the advantages that: the dependence on the network environment is greatly reduced, so that the terminal equipment can also verify whether the deduction is carried out or not in the non-network environment.
The charging efficiency is improved, offline payment is compared with online payment, the payment speed is greatly improved, and the charging efficiency is improved.
Reduce equipment cost, terminal equipment need increase bluetooth module and two-dimensional code and sweep the sign indicating number module, but need not to dispose network module, insert coins module, IC buckle money module, generally speaking, reduces hardware cost.
The network operation cost is reduced, and the network operation expense is not required to be considered for an operator.
The coin-freed charging device has the advantages that the coin-freed charging is not needed, and the labor cost for recycling the coins is not needed, so that the operation and maintenance cost of the whole system is reduced.
The above embodiments are provided to further explain the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
