At present, with the rapid development of intelligent technology, people have higher and higher requirements for power quality. Edge computing, as an important tool for effectively processing power system data and simulating related processes, realizing machine learning functions, and performing mathematical modeling, is widely used in various fields. The integration of intelligent units and edge computing is a strong technology with a wide range of applications, involving multiple disciplines such as power systems, network communications, and computers. At the same time, in today's power system, in some cases, grid parameters and power consumption information cannot be monitored and read in real time, which seriously affects the operational safety of the entire grid to a large extent. Therefore, in order to better guarantee the quality of power supply and reduce energy consumption, research on grid parameter collection systems based on the integration of smart units and edge computing is carried out. This paper adopts experimental analysis method and data analysis method, which is intended to improve the stability and controllability of the grid parameter collection system by combining the advantages of intelligent units and edge algorithms. According to the experimental results, it can be seen from the experimental data that the output value of the power acquisition circuit is slightly higher than the calculated value, indicating that there is a measurement error, but the error is relatively small. In addition, if the power consumption of the test platform itself is removed, the two data sets will be closer, and it can be concluded that the power data acquisition and processing circuit has higher measurement accuracy. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

With the construction of state grid informatization, professional data such as operation inspection, marketing, and regulation have gradually shifted from offline to online. In recent years, cyberspace security incidents have occurred frequently, and national and group cybersecurity threats have emerged. As the next-generation communication system, quantum security has to satisfy the security requirements. Also, it is especially important to build the fusion application of energy network quantum private communication technology and conventional network, and to form a safe and reliable quantum-level communication technology solution suitable for the power grid. In this paper, from the perspective of the multi-terminal quantum key application, combined with a mature electricity consumption information collection system, a handheld meter reading solution based on quantum private communication technology is proposed to effectively integrate the two and achieve technological upgrading. First, from the technical theory and application fields, the current situation of quantum private communication technology and its feasibility of combining with classical facilities are introduced and analyzed. Then, the hardware security module and handheld meter reading terminal equipment are taken as typical examples to design and realize quantum key shared storage, business security process application model;finally, based on the overall environment of quantum key distribution, the architecture design of multi-terminal quantum key application verification is implemented to verify the quantum key business application process. © 2020 IEEE.

With the rapid development of information technology, the number of Internet of things devices is growing rapidly, and the need to ensure its information security is becoming more and more urgent. In this application context, as a lightweight hardware encryption primitive, physical unclonable functions come onto the stage. This paper proposes a software PUF design, OCP-PUF, based on the internal timing difference of the processor. This PUF is based on the difference of the delay path in the processor pipeline, takes a specific instruction group input as a challenge, and response based on the instruction error that occurs after the clock overclocking. This design does not need to configure any additional hardware resources, nor does it need to make any changes to the hardware of the device. So it can be easily deployed on existing devices, which fits the current application background of low power consumption and low resource occupation. In the work of this paper, its principle and incentive response mechanism are described in detail, and its implementation based on RISC-V instruction set architecture on FPGA platform is verified and analyzed. The results verify that its uniqueness and stability are similar to that of traditional PUF, but it reduces resource occupation.

In practice, different styles of side channel attacks can utilize the leakages of a crypto device to recover the used secret key, which can pose a serious threat on the physical security of a crypto device. Among different styles of side channel attacks, template attack can be information theoretically the strongest attack style. However, numerical problems can seriously influence the key-recovery efficiency of template attack in practice, which can make template attack useless in practice. In light of this, the variance analysis based distinguisher is proposed for template attack. Compared with the classical template attack, variance analysis based template attack can reduce the computational complexity of template attack from $O(d^analysis)$ to $O(d)$ , where $d$ denotes the number of interesting points. Besides, numerical problems do not exist anymore. Therefore, a large number of interesting points can be chosen to enlarge the leakage exploitation and accordingly optimize the key-recovery efficiency of template attack. The key-recovery efficiency of variance analysis based template attack is evaluated in both simulated and real scenarios, and the evaluation results show that compared with the classical template attack, variance analysis based template attack can maintain a high key-recovery efficiency while significantly decrease the number of traces that should be used in the profiling phase of template attack.

This thesis presents a method that a position measurement method for moving targets is proposed based on the positioning method based on the time difference of arrival(TDOA) which is based on the research on the positioning problem of station inspection operators and equipment in complex working conditions. The probability error method is introduced to optimize the traditional positioning method that realizes the target node positioning by optimizing the distance difference between the target node to be located in the network domain environment and different base stations, which can effectively improve the positioning accuracy of staff and equipment in the station. Through experiments in a complex power frequency electric field environment, the test results show that the results calculated by the optimization method are better than the existing traditional positioning methods, and can effectively improve the positioning accuracy under the condition of line-of-sight, and realize the substation space Mobile target positioning to ensure the safety of operators.

power companies, the data collected by smart meters on electricity consumption is of vital interest. In 2019, Wang had a dispute with Ping Dingshan. They came into disagreement regarding the amount of electricity consumed, which was a difference of 1334 kWh. It was not settled until 2021. To avoid the above problem, smart meters could upload power information to the blockchain. In this paper, we improved the authentication protocol key proposed by Zhang and proposed a new scheme for uploading the power information from smart electricity meters, which ensures the integrity, confidentiality and authentication of the power information. At the same time, the proposed scheme is unbalanced for the computing capability of both communication parties, and can effectively reduce the burden of the server.

With the development of society, intelligent terminal equipment is used more and more widely. The use of intelligent terminals to locate children's position, to ensure that children are in a safe and controllable range, is more favored by parents. But now the smart watch needs to install the mobile phone card, which depends on the mobile phone traffic to locate, and the cost is relatively high. This paper proposes a Bluetooth low energy warning method to solve this problem. The distance between the two devices is calculated by the signal strength indication value received by the intelligent terminal, and then compare the preset received signal strength indication value with the received signal strength indication value, as well as the preset distance value and the calculated distance value of the two devices. When the received signal strength indication value is less than the preset value or the distance between the devices exceeds any of the preset values, the wireless device and the intelligent terminal will send an alarm at the same time to remind the two sides wearing the intelligent terminal and the Bluetooth device that the distance between the two sides has exceeded the safety value. The Bluetooth low energy warning method proposed in this paper has the characteristics of low cost and low energy consumption. © Published under licence by IOP Publishing Ltd.
