[0002] With the rapid development of IoT technology and the popularization of 5G networks, the application of power IoT is becoming increasingly widespread. In power IoT, various sensors, measuring devices, and control systems can monitor the status of the power grid in real time, providing important support for power production and energy management. However, this network also brings some security threats, such as data leakage and malicious attacks. Network slicing technology utilizes virtual network slicing technology to provide customized network services for different applications, thereby improving network security and reliability. To solve these security problems, this invention proposes a power IoT security management system based on 5G network slicing, combined with 5G network slicing technology.

[0003] For example, Chinese Patent Publication No. CN112616124A discloses a power IoT security management method and system based on 5G network slicing. The method includes: a 5G operator performing identity and permission authentication based on authentication requests sent by distribution automation terminals; forming a security configuration file based on the authentication results, relevant parameters and security requirements of the determined slice type, and specific security services required in the distribution automation; arranging the security configuration file into the corresponding network slice; training the collected security data using an artificial neural network algorithm to construct a slice security model, obtaining a security control strategy; and adjusting and updating the security configuration file according to the security control strategy to achieve security management of the power IoT. This invention provides more intelligent identification of security threats in distribution automation slice networks, more diversified security deployment, and more secure and reliable 5G authentication.

[0004] The existing technology has the following problems: In power safety management, due to different user needs, there may be situations where the overall system bandwidth and network configuration are not compatible, which can easily lead to an increase in the data transmission time and cost of the overall system. In addition, the traditional power safety management system lacks flexibility and it is difficult to allocate resources and adjust the load in a timely manner, resulting in a waste of overall system resources. Summary of the Invention

[0005] The purpose of this invention is to provide a power Internet of Things security management system based on 5G network slicing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A power Internet of Things (IoT) security management system based on 5G network slicing includes a 5G network module, an IoT and security equipment module, a network slice manager module, a blockchain technology module, and a multi-party secure computation module.

[0008] The 5G network module is used to provide high-speed, low-latency, high-reliability and high-security communication support. The 5G network is the basic architecture of the system. In the 5G network, network slicing technology is the key to realizing the differentiation and personalization of IoT services.

[0009] The IoT and security device module is used to monitor the status of the power system in real time, collect and transmit large amounts of data, and transmit the data to other modules for analysis and processing.

[0010] The network slice manager module is used to manage and control the 5G network, providing differentiated and personalized network services for different IoT applications, and is a key component of the system.

[0011] The blockchain technology module is used to encrypt and share data, allowing multiple participants to share and update a distributed ledger, ensuring the security and integrity of the data;

[0012] The multi-party secure computation module is used to protect the privacy and confidentiality of data, allowing multiple participants to complete computation and analysis tasks without sharing the actual data.

[0013] A further improvement of the technical solution of the present invention is that the Internet of Things and security equipment module includes sensors, controllers, smart meters, firewalls, intrusion detection modules and prevention devices, protecting the network from malicious attacks and data leakage threats.

[0014] A further improvement of the technical solution of the present invention is that the network slice manager module includes a resource slicing unit, a slice bandwidth optimization unit, a slice latency control unit, and a slice security optimization unit;

[0015] The resource slicing unit is used to slice the 5G network into multiple independent logical networks according to the needs of IoT applications. Each slice is optimized according to its specific needs, provides specific security measures, and divides the network into different network virtualization layers. Each layer has its own independent network configuration, control and management.

[0016] A further improvement to the technical solution of this invention lies in that: the slice bandwidth optimization unit is used to manage the bandwidth performance, resource optimization allocation, and security measures of slices, and its calculation formula is as follows:

[0017] bi = (B * qi) / q;

[0018] Where B is the total bandwidth of the network, qi represents the specific quality requirements of the i-th slice and application, and q is the sum of the quality requirements of all slices and applications.

[0019] A further improvement to the technical solution of this invention lies in that: the slice delay control unit is used for the control and supervision of network slices, manifested as traffic delay control and load balancing, and its calculation formula is as follows:

[0020] di <= D / n;

[0021] Where D is the total network latency, n represents the total number of slices and applications participating in scheduling, and di is the maximum latency of the application.

[0022] A further improvement of the technical solution of the present invention is that: the slice security optimization unit is used for the security management and protection of network slices, uses encryption algorithms to encrypt and decrypt data, and implements access control operations according to the slice policy.

[0023] A further improvement of the technical solution of the present invention is that: the multi-party secure computation module is used to realize data privacy protection. The calculation formula adopts a secret sharing method. The public key among the participants is pk, and the private key is sk. The private data of each participant is secretly shared to generate n shared secret values ​​s1, s2, ..., sn. The participants encrypt the shared secret values ​​using an encryption algorithm to generate encrypted values ​​c1, c2, ..., cn, and send these values ​​to the multi-party secure computation module. Inside the multi-party secure computation module, these encrypted values ​​are calculated, and the calculation result is sent to the participants.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, such as Figure 1 As shown, the present invention provides a power Internet of Things (IoT) security management system based on 5G network slicing, including a 5G network module, an IoT and security equipment module, a network slice manager module, a blockchain technology module, and a multi-party secure computation module;

[0033] 5G network modules are used to provide high-speed, low-latency, high-reliability, and high-security communication support;

[0034] The Internet of Things (IoT) and security equipment module is used to monitor the status of the power system in real time, collect and transmit large amounts of data, and transmit the data to other modules for analysis and processing. The IoT and security equipment module includes sensors, controllers, smart meters, firewalls, intrusion detection modules, and prevention devices to protect the network from malicious attacks and data leakage threats.

[0035] The Network Slice Manager module is used to manage and control 5G networks, providing differentiated and personalized network services for different IoT applications;

[0036] Blockchain technology modules are used to encrypt and share data, allowing multiple participants to share and update a distributed ledger;

[0037] The multi-party secure computation module is used to protect the privacy and confidentiality of data, allowing multiple participants to complete computation and analysis tasks without sharing the actual data.

[0038] Example 2, as Figure 1-2 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, the network slice manager module includes a resource slice unit, a slice bandwidth optimization unit, a slice latency control unit, and a slice security optimization unit;

[0039] The resource slicing unit is used to slice the 5G network into multiple independent logical networks according to the needs of IoT applications. Each slice is optimized according to its specific needs, provides specific security measures, and divides the network into different network virtualization layers. Each layer has its own independent network configuration, control and management.

[0040] The slice security optimization unit is used for the security management and protection of network slices. It uses encryption algorithms to encrypt and decrypt data and implements access control operations according to the slice policy.

[0041] Furthermore, the slice bandwidth optimization unit is used to manage the bandwidth performance, resource optimization allocation, and security measures of slices. Suppose the total network bandwidth is B, which needs to be allocated to n different slices and applications. Assuming the i-th slice and application requires a minimum bandwidth of bi, bandwidth allocation and optimization can be performed using the following formula:

[0042] bi = (B * qi) / q;

[0043] Where qi represents the specific quality requirements of the i-th slice and application, and q is the sum of the quality requirements of all slices and applications;

[0044] Furthermore, the slice latency control unit is used for the control and management of network slices, manifested in traffic latency control and load balancing. Let the total network latency be D, and the latency requirements of n different slices and applications need to be met. Assuming the maximum latency of the i-th slice and application is di, latency optimization can be performed using the following formula:

[0045] di <= D / n;

[0046] Where n represents the total number of slices and applications participating in the scheduling.

[0047] Example 3, as Figure 1-2 As shown, based on embodiments 1-2, the present invention provides a technical solution: Preferably, the multi-party secure computation module is used to realize data privacy protection. In the multi-party secure computation module, there are multiple participants, each of whom has their own private data. Assuming there are n participants, each possessing data x1, x2, ..., xn, the multi-party secure computation module needs to perform a certain calculation, but for the sake of privacy protection, it does not want the participants to transmit all of their private data. Therefore, the multi-party secure computation module needs to use a certain protocol to allow the participants to transmit only encrypted data without revealing their actual data.

[0048] Furthermore, the calculation formula of the multi-party secure computation module adopts a secret sharing method. Assuming that the public key among the participants is pk and the private key is sk, the multi-party secure computation module first secretly shares the private data of each participant, generating n shared secret values ​​s1, s2, ..., sn. Then, the participants encrypt the shared secret values ​​using an encryption algorithm, generating encrypted values ​​c1, c2, ..., cn, and send these values ​​to the multi-party secure computation module. Inside the multi-party secure computation module, these encrypted values ​​are calculated, and the calculation result is sent to the participants.

[0049] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
