First, information security issues in the Internet of Things era
At present, the Internet of Things has been widely used in people's production and life, such as security monitoring and QR code scanning. It is no exaggeration to say that the future will be an era of Internet of Things. Because the core foundation of the Internet of Things is the Internet, the Internet of Things will also face the security problem that classified information is attacked by hackers in its development, so a major obstacle to the rapid development of the Internet of Things is information security.
First, the information security problems existing in the application layer of the Internet of Things. The application layer of the Internet of Things is the top layer of the three-tier structure. From the analysis of the three-layer structure of the Internet of Things, the network layer and the perception layer are relatively mature in technology, while the application layer still has some problems in attention and technical achievements. Because "data" and "application" are the core functions of the application layer, the application layer system of the Internet of Things needs to analyze, process and sort out the data, and finally combine the sorted data with various applications. For example, the application of the Internet of Things in the medical field is through the processing and sorting of medical data, and then combined with the platform system for application. As the ultimate receiver of data, the application layer of the Internet of Things has an unshirkable responsibility for information security.
The second is the information security of the Internet of Things in the network layer. The network layer of the Internet of Things is the middle layer of the three-tier structure, and its main function is "transportation", so it can also be called the transportation layer. From the analysis of the three-layer structure of the Internet of Things, the network layer plays the role of a link, connecting the perception layer and the application layer of the Internet of Things. Because the network layer needs to obtain the information of the perception layer and then transmit it to the application layer safely, the Internet of Things also has the information security problem of the network layer. Because the basic core of the Internet of Things is the Internet, and the Internet has the characteristics of unstable environment, the Internet of Things can easily become the target for criminals to steal information at the transmission level.
The third is the information security of the Internet of Things in the perception layer. In the three-tier structure of the Internet of Things, the perception layer is at the bottom and is the easiest to be broken. Because the main function of the perception layer is to obtain data information.
Second, measures to deal with information security in the Internet of Things era
First, the Internet of Things should take measures at the application level to deal with information security issues and strengthen the security management of data applications. This is mainly divided into several aspects: (1) Design access rights for data, because different customer groups design different access rights. This can effectively limit the user's application operation and ensure the information security of the same customer group; (2) Strengthen the management of data authentication system, such as key technologies, which must strengthen the authentication system to prevent criminals from invading and stealing user information; (3) Intensify the crackdown on cyber criminals. In this regard, it is necessary to intensify the crackdown on criminals who steal information, improve relevant laws and regulations in law, and ensure that there are laws to follow and laws to be followed;
(4) Integrate the management between different networks. Because different networks have different technical management, it is easy to provide attack space for criminals, so I hope to establish a data center that can be managed centrally in the future.
The second is the measures taken by the Internet of Things to deal with the information security problems in the network layer, and the node problems need to be solved. This is mainly divided into several aspects: (1) the encryption system is processed on the peer node, and then the information is transmitted, which can effectively concentrate the information and protect the security of the information in the transmission process; (2) The encryption system is processed at the end-to-end node, and different encryption conditions can be adopted for different user information, thus protecting the security of user information more flexibly and effectively; (3) Accelerate cross-network authentication. Only by reducing the transmission time can the attack space of criminals be effectively compressed, thus protecting the transmission security of user information.
Third, the Internet of Things should take measures to deal with information security issues at the perception level. What needs to be done is to improve the identification technology, directly and effectively protect the security of rfid, and eliminate the security risks at the perception level. Fingerprint identification, for example, is to label the user's identity. In addition, it is necessary to improve the technical operation of sensors, further study the security routing and user security information, and strengthen the protection of user privacy information.
The future world is a developing world of Internet of Things. However, there are still many problems in the development of Internet of Things in China, especially the leakage of user privacy information. It is necessary to gradually solve the problems existing in the information security of the Internet of Things. Only by solving the problem of information security, protecting users' information security, protecting people's economic and property security and protecting national security can the Internet of Things develop rapidly and usher in the information age in China.
