[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides a technical solution: a network security protection encryption device, including a terminal and a corresponding network security protection encryption system.

[0026] The terminal's main body 1 is the core physical support of the entire device, and its durable shell design is crucial. This shell is made of high-strength materials and can effectively resist various physical impacts from the outside, such as accidental collisions and falls. At the same time, it can also resist environmental interference, including temperature, humidity, dust, and electromagnetic interference. Under different environmental conditions, whether it is a hot and humid industrial environment or a dry and dusty office environment, the main shell can ensure the normal operation of the terminal's internal components.

[0027] The heat dissipation system inside the main body 1 is the key to ensure the long-term stable operation of the terminal. The heat dissipation system consists of an efficient heat dissipation fan and a heat dissipation channel. The heat dissipation fan adopts advanced intelligent speed regulation technology. It has a built-in temperature sensor that can sense the temperature changes inside the terminal in real time. When the temperature rises, the fan will automatically increase the speed to enhance the heat dissipation effect. For example, when the terminal performs high-intensity data encryption processing or runs large applications for a long time, the internal temperature will rise rapidly. At this time, the heat dissipation fan will quickly adjust the speed according to the temperature change to ensure that the heat can be dissipated in time. At the same time, the design of the heat dissipation fan also focuses on reducing noise. It uses a special blade structure and motor control technology, so that the noise generated during high-speed operation can also be controlled within an acceptable range and will not interfere with the user's work and living environment.

[0028] The design of the heat dissipation channel has been carefully considered, and its shape, size and material have been optimized. The inner wall of the channel is made of high thermal conductivity material, which can quickly transfer heat from the inside of the terminal to the vicinity of the cooling fan so that the fan can discharge the heat. The direction of the channel also conforms to the principle of hot air rising, which can effectively guide the flow of heat and improve the heat dissipation efficiency. This reasonable heat dissipation channel design cooperates with the cooling fan to provide a strong guarantee for the stability and reliability of the terminal during long-term operation.

[0029] The main body 1 and the control panel are made of environmentally friendly materials, which reflects the environmentally friendly design concept. When selecting materials, the durability and recyclability of the materials are fully considered. Environmentally friendly materials must not only meet the requirements of device performance and safety, but also meet the goals of sustainable development. For example, the main body shell may be made of recyclable high-strength plastic, which has sufficient strength and can be recycled and reused after the terminal ends its service life, reducing waste emissions to the environment. The control panel may use environmentally friendly electronic materials, which have less impact on the environment during production and use, and can also ensure the normal function of each component on the control panel.

[0030] The main control panel 2 is the main interface for the user to interact with the terminal, and is equipped with a variety of important components. The switch button 21 is the most basic operating element, which is used to control the startup and shutdown of the terminal. When the user presses the switch button 21, the power system of the terminal will start the corresponding circuit, start initializing each component, and put it into working state. When the terminal needs to be shut down, press the switch button 21 again, and the power system will shut down each component according to the predetermined program to ensure the safe storage of data and the normal shutdown of the system.

[0031] The fingerprint identifier 22 is a key component to improve the security of the terminal. It uses advanced fingerprint recognition technology and can quickly and accurately identify user fingerprints. During the recognition process, the fingerprint identifier 22 first collects the fingerprint image on the user's finger, and then extracts and compares the fingerprint image through an internal algorithm. Only authorized users whose fingerprint features match the fingerprint template pre-stored in the terminal can unlock the control panel and operate it through fingerprints. This fingerprint recognition technology has the characteristics of high recognition rate and low false recognition rate, and can work stably even when the fingers are dirty, wet or under different lighting conditions. For example, in some industrial environments, the operator's fingers may be oily, but the fingerprint identifier 22 can still accurately recognize the fingerprint, providing users with a convenient and safe operation experience.

[0032] The indicator light 23 plays an important role in providing information on the main control panel 2. It can display important information such as network security status and encryption progress in real time. For example, when the network security protection encryption system detects a potential security threat, the indicator light 23 will flash red to alert the user. When the data encryption module is encrypting data, the indicator light 23 will display different colors or flashing frequencies to indicate different stages of the encryption progress. The user can intuitively understand the working conditions of the terminal and the network security protection encryption system by observing the status of the indicator light 23.

[0033] There are also various function buttons on the main control panel 2, which are used to start or stop encryption, switch security modes, perform system settings, etc. For example, when a user needs to encrypt a file or folder, he can press the encryption function button, and the data encryption module will encrypt the corresponding data according to the user's instructions. If the user needs to enter a different security mode, such as advanced security mode or normal security mode, it can be achieved by switching the security mode button. The system setting button allows the user to set some basic parameters of the terminal, such as network connection settings, user authority settings, etc.

[0034] The terminal panel 3 is used to connect related external devices. It may include various types of interfaces, such as a USB interface, an Ethernet interface, an HDMI interface, etc. The USB interface can be used to connect external storage devices, such as a USB flash drive, a mobile hard disk, etc., to facilitate data transmission and storage for users. The Ethernet interface is used to connect to the network, so that the terminal can communicate with other devices over the network to achieve data sharing and interaction. The HDMI interface can be used to connect to an external display. When the user needs to display the content of the terminal on a larger screen, the video signal of the terminal can be output to the external display through the HDMI interface.

[0035] The network security protection encryption system includes a data encryption module, an intrusion detection module, an access control module, a security audit module and an emergency response module.

[0036] The data encryption module uses advanced encryption algorithms to perform high-intensity encryption on the data transmitted by the terminal. Whether it is stored locally or transmitted over the network, the data can be reliably protected to prevent illegal theft or tampering.

[0037] This module can automatically identify different types of data and select the appropriate encryption level according to its importance and sensitivity. For some ordinary text files, a relatively low encryption level may be used to improve encryption speed and system performance. For some files containing sensitive information, such as corporate financial data, personal ID numbers, etc., a higher encryption level will be used. For example, for the financial statement data of an enterprise, the data encryption module may use a multi-layer encryption algorithm to first encrypt the data symmetrically and then encrypt it asymmetrically to ensure the security of the data.

[0038] It supports multiple encryption algorithms, including symmetric encryption algorithms and asymmetric encryption algorithms. Users can choose the appropriate encryption algorithm according to actual needs.

[0039] Symmetric encryption algorithms have the characteristics of fast encryption speed and high efficiency, and are suitable for encrypting large amounts of data. For example, when encrypting a large database of an enterprise, the use of symmetric encryption algorithms can complete the encryption task in a shorter time. Symmetric encryption algorithms use the same key for encryption and decryption, so the key security must be ensured during use.

[0040] Asymmetric encryption algorithms have higher security and are suitable for key exchange and digital signature scenarios. In asymmetric encryption algorithms, a pair of keys, namely a public key and a private key, are used. The public key can be made public and used to encrypt data, while the private key is kept by the user and used to decrypt data. For example, when conducting online transactions, merchants can use the customer's public key to encrypt transaction information. After receiving the encrypted information, the customer uses his own private key to decrypt it, which ensures the security of the transaction information.

[0041] The data encryption module can automatically switch between different encryption algorithms to meet different security requirements. For example, when the system detects that the amount of data being processed is large and the security requirements are not particularly high, it may automatically switch to a symmetric encryption algorithm. When the processed data contains very sensitive information, it will automatically switch to an asymmetric encryption algorithm, or use a combination of multiple encryption algorithms for encryption.

[0042] The intrusion detection module constantly monitors abnormal behaviors and potential intrusions in the network. By analyzing network traffic and system log information, it can promptly detect malicious attacks, illegal access and other behaviors and issue an alarm.

[0043] This module will monitor network traffic in real time and analyze network traffic flow direction, flow size, protocol type and other characteristics. For example, if a certain IP address suddenly sends a large number of abnormal data packets, or the flow of data packets does not conform to the normal network communication mode, the intrusion detection module will regard it as a potential intrusion behavior. At the same time, the analysis of system log information is also very important. The system log records various operations and events of the terminal and network system. The intrusion detection module will find out whether there are abnormal operation records, such as unauthorized user login attempts, illegal modification of system files, etc.

[0044] With intelligent learning function, it can continuously adapt to new security threats and improve the accuracy and timeliness of detection. As the network environment continues to change and new security threats emerge, the intrusion detection module can automatically learn new attack patterns and behavioral characteristics, and adjust the detection strategy to adapt to the new security situation. For example, when a new network virus appears, the intrusion detection module will learn how to identify the virus by analyzing the virus's propagation mode and behavioral characteristics, and then adjust its own detection strategy so that it can detect similar viruses faster and more accurately in the future.

[0045] With self-learning and self-adaptation capabilities, as the network environment continues to change and new security threats emerge, the intrusion detection module can automatically learn new attack patterns and behavior characteristics, and adjust the detection strategy to adapt to the new security situation. The module can also work with other security devices to jointly build a more complete network security protection system. For example, when the intrusion detection module detects potential intrusion behavior, it can work with the firewall to notify the firewall to block the relevant IP addresses to prevent malicious attacks from spreading further.

[0046] Access Control Module Strictly limit access rights to terminals and network resources. Only authorized users or devices can access, effectively preventing unauthorized access and abuse.

[0047] Use a role-based access control strategy to assign appropriate access rights to users based on their roles and responsibilities in the organization. For example, in an enterprise, senior executives may have full access to all network resources, including viewing and modifying the core data of the enterprise. Ordinary employees may only have access to some network resources related to their work, such as viewing their work files and using some basic office software. This access control strategy can manage user access to network resources more finely and improve the accuracy and efficiency of access control.

[0048] At the same time, the access control module also supports dynamic authorization and permission revocation, and can adjust the user's access rights in a timely manner when the user's role or responsibilities change. For example, if an ordinary employee is promoted to a department head, the access control module will promptly assign him more access rights based on his new role and responsibilities, including viewing and managing the work files of other employees in the department. Conversely, if a department head is demoted to an ordinary employee, his access rights will be revoked accordingly, and only the access rights that match the role of an ordinary employee will be retained.

[0049] The security audit module comprehensively records and reviews network activities, including user operations, network access, and data transmission information, so as to facilitate tracing and analysis when security incidents occur.

[0050] By analyzing the audit records, potential security vulnerabilities and risks can be discovered, providing a basis for further strengthening network security protection. For example, if the audit records show that a user has failed to log in to the system multiple times in a short period of time, and then successfully logged in, this may indicate the risk of password cracking. Or if the audit records show that a certain IP address frequently accesses some sensitive network resources, but the IP address does not have the corresponding access rights, this may indicate the risk of illegal access.

[0051] It has real-time monitoring and early warning functions. In addition to recording and reviewing network activities, it can also monitor the security status of the network in real time and issue early warnings in time when abnormal situations are found. The early warning information can be notified to the administrator in a variety of ways, such as email, SMS, etc. For example, when the security audit module detects that a user is performing abnormal network operations, such as deleting a large number of important files, it will immediately issue an early warning message to the administrator, who can take timely measures to deal with it and prevent further deterioration of the security incident.

[0052] Emergency Response Module When a security incident occurs, it will be activated quickly and appropriate emergency measures will be taken, such as cutting off the attacked network connection, starting the backup system, notifying the administrator, etc.

[0053] Including backup and recovery system, when a security incident occurs, the backup and recovery system can be quickly started to restore the affected data and system to the previous safe state. The backup and recovery system adopts a combination of regular backup and real-time backup to ensure data integrity and availability.

[0054] Regular backup is to back up data and systems at predetermined time intervals. For example, you can set up a backup of important data and systems every night. In this way, when a security incident occurs, if it occurs after the backup time, you can use the most recent regular backup data for recovery.

[0055] Real-time backup is to back up data immediately when it changes. For example, for some important databases, when new data is inserted or modified, the real-time backup system will immediately back up the changed data. In this way, when a security incident occurs, if it occurs between two regular backups, the real-time backup data can be used for recovery to ensure data integrity and availability.

[0056] At the same time, the backup environment system also has a rapid recovery function, which can restore the system to normal operation in the shortest time and reduce the impact of security incidents on the business. For example, if the company's financial system is attacked, the emergency response module will quickly cut off the attacked network connection, start the backup system, and use the most recent backup data to restore the financial system to its previous safe state, and get the financial system back up and running in the shortest time possible, avoiding long-term impact on the company's financial business.

[0057] Remote management capabilities The network security protection encryption system also has a remote management function. The administrator can remotely manage and monitor the terminal and the network security protection encryption system through the network.

[0058] Remote management functions include remote configuration, remote upgrade, and remote troubleshooting, making it convenient for administrators to uniformly manage and maintain network security protection encryption devices.

[0059] Remote configuration means that the administrator can remotely set various parameters of the terminal and network security protection encryption system through the network. For example, the administrator can remotely set the encryption algorithm of the data encryption module and the access permission setting of the access control module.

[0060] Remote upgrade means that the administrator can remotely upgrade the software of the terminal and network security protection encryption system through the network. When there is a new security patch or function update, the administrator can remotely start the upgrade program to ensure that the terminal and network security protection encryption system always maintain the latest security performance and functions.

[0061] Remote troubleshooting means that administrators can remotely check and solve problems that occur in terminals and network security protection encryption systems through the network. For example, if there is a network connection problem on the terminal, the administrator can use the remote management function to view the terminal's network settings, check the network interface status, etc., and then take appropriate measures to solve it.

[0062] The remote management function uses secure encryption technology to ensure the security and reliability of the management process. For example, during remote configuration, remote upgrade, and remote troubleshooting, all data transmission is encrypted using encryption algorithms to prevent data from being stolen or tampered with during transmission. At the same time, the remote management function will also verify the identity of the administrator, and only authorized administrators can perform remote management operations, ensuring the security and reliability of the management process.
