An electric vehicle charger fee payment method using virtual currency according to an embodiment of the present invention is a payment method for paying an electric vehicle charging fee through a power transaction between a prosumer and the electric car charger user based on a block chain,
Conducting a power transaction between a prosumer and an individual electric vehicle charger user based on the block chain (S110); Providing the surplus power to a nearby electric vehicle charger (S120); It is characterized by including a step of generating real-time power generation and transaction data by interconnecting power systems based on a block chain (S130) and a step of monitoring packets for a platform safe from hacking (S140).
The virtual currency payment method for electric vehicle charging charges of the present invention is characterized in that insufficient power of electric vehicle charging station chargers can be supplied through KEPCO.
In particular, it is characterized by including domain blocking, packet monitoring, and CPU monitoring for a platform that is safe from hacking and can be guaranteed by a third party.
The domain blocking method is characterized by storing a separate IP and domain name in a hosts file; The packet monitoring method is characterized in that it includes mining server connection detection, mining server connection detection, mining result transmission detection, and stratum protocol detection.
The CPU monitoring method checks the CPU usage rate for each running process; If the CPU usage rate of the specific process exceeds the reference value, intensively monitors the CPU usage rate of the specific process for 1 minute; If the high CPU usage rate continues during the monitoring time, the entire memory of the specific process is dumped, and whether a string related to mining exists in the memory is checked in the dump, and the specific process is terminated when the string is confirmed. .
The prosumer 19 uses the generated power and provides the remaining power to an electric charging station, and the consumer 11 can charge the supplied power through the electric charging station. At this time, the electric charging station may be supplied to the user 11 through the prosumer 19, but insufficient power may be supplied through the KEPCO.
Blockchain technology enables electricity trading using distributed energy. In particular, solar energy generates a lot of surplus energy because the amount of power generation fluctuates greatly depending on the amount of solar radiation, which leads to an increase in the cost of expanding the capacity of the power system when it is consumed at a distance.

Therefore, the surplus energy is sold to nearby electric charging stations linked to the system, and the transaction system and the existing power system are interconnected using the central block chain to create real-time power generation and transaction data, automatically and safely conduct transactions, and record records. The function of leaving is possible with blockchain. This is because it makes it easy to record and store information of producers and consumers according to energy production, and to identify and track the flow of electricity use. By paying with cryptocurrency using blockchain technology, it is possible to trade between energy producers such as solar and nearby electric charging stations.

According to the present invention, the electric vehicle charging amount and charging fee can be identified, the charging fee to be paid can be automatically paid in virtual currency through an app installed on the portable terminal, and the charging fee can be paid in virtual currency.

As a method of defending against ransomware that hacks virtual currency traded in the present invention, domain blocking, packet monitoring, CPU monitoring, and process command line inspection are used. How to block a domain is as follows. The malicious code makes a DNS query to connect to the mining server. If the mining server IP cannot be obtained from the DNS server, the connection to the server is not made, so a domain blacklist is designated and blocked so that this process does not go through. If you save a separate IP and domain name in the hosts file, you can connect to the separately designated IP by referring to the hosts file without going through the DNS query process to obtain the website IP to access.

Packet monitoring is a method of monitoring network packets to detect the behavior of ransomware communicating with the server. This blocks the process that sent the packet when data matching a specific string detection rule is detected in the packet. The detection rules are as follows.

[1] /^\{\".*\"method\".*\"agent\".*\"xmr

[2] /^\{\".*\"method\".*\"agent\".*miner

[3] /^\{\".*\"method\".*\"submit\".*\"nonce\"

[4] /^\{\".*\"method\".*\"mining\.

Above, [1] indicates mining server connection detection, [2] mining server connection detection, [3] mining result transmission detection, and [4] stratum protocol detection.

The rule detects “{” and “method” strings at the beginning of the packet. Rules in [1] and [2] detect “agent” and “xmr” or “miner” strings indicating the type of program when connecting to the mining server. When the malicious code sends the result to the server, “submit” and “nonce” strings are used, so apply [3] Rule to detect it. [4] Rule is “mining.” to detect “mining.authorize”, “mining.submit”, etc. detect string When a packet is detected by the detection rule, the process using the port from which the packet was sent is found and terminated.

<Example 2>
The detection and blocking flow of the CPU monitoring method is shown in FIG. 6 .
The detection and blocking method of the CPU monitoring method includes the steps of checking the entire process list (S210); Selecting a process and checking CPU usage (S220); Thereafter, if the high CPU usage rate (S230) does not correspond (No), proceed to the last process (S290) and terminate, and if the high CPU usage rate (S230) corresponds to (Yes), monitoring the corresponding process for a certain period of time (S240); If "No" in the step of determining whether the CPU usage rate continues (S250), the process proceeds to the last process (S290) and ends. If it is "yes" by determining whether the CPU usage rate continues (S250), performing a memory test (S260); Determining detection of a mining string (S270); If "No", it proceeds to the last process (S290) and ends.
In the step of determining the mining string detection (S270), if "Yes", the process ends (S280) and proceeds to the last process (S290) to end.

delete

That is, first, the CPU utilization rate of all running processes is checked. If the CPU usage rate of a specific process exceeds the standard value, the CPU usage of the process is intensively monitored for 1 minute. If high CPU usage continues during the monitoring time, dump the entire memory of the process and check if the string related to mining exists in the memory. When the string is verified, the process is terminated.

Here's how to check the process command line: In the method of executing ransomware through a new process, since all running processes have execution command line information, malicious processes are detected by checking mining-related strings included in the execution command line. Therefore, it inspects all running processes, obtains a list of all processes, and checks the execution command line for each process. If the string to be detected is identified, the process is terminated to block access. An example of a mining malware execution command line is:

[malware.exe -o stratum+tcp://xmr.pool.minergate.com:45700 -u test@gmail.com-p x --donate-level=1 -t 2 -k --av=1 -- cpu-affinity 60 --config=config.json]

The file name of the mining malware executed through the above example is “malware.exe” and the address of the mining server to be connected is “stratum+tcp://xmr.pool.minergate.com:45700”. “cpu-affinity” is an option that prevents malware from occupying more than a specified number of CPU usage. The detected process is immediately terminated to block mining activity.

The present invention is not limited to the above presented drawings, and may be embodied in other aspects. In addition, unless otherwise defined, the terms used in the specification of the present invention have meanings commonly understood by those of ordinary skill in the art to which the present invention belongs, and the subject matter of the present invention is described in the description and accompanying drawings of the present invention.
