Introduction of the DTU Transmission encryption method

With the rapid development of network information, the network affects all aspects of people, but the security problems that come with it become more and more prominent, so people's privacy requirements of network activities are more and more high. So the data encryption technology is born, the use of data encryption technology, to ensure that people in the network activities of data transmission security, while ensuring their own data and information confidentiality requirements.

Data encryption refers to the conversion of plaintext into ciphertext through cryptographic algorithms and encryption keys, while decryption is the process of reverting ciphertext to plaintext by decrypting the algorithm and decryption key. Data encryption is still a reliable method for computer communication to protect information, and it can be used to encrypt information, realize information concealment, and thus play a security role in protecting information.

Currently in the market Dtu/rtu data transmission is clear text transmission, security is guaranteed by TCP/IP, security level is low. How to ensure the security of DTU/RTU data during transmission? Now most of the way is to use the APN/VPDN private network services provided by operators to ensure the security of DTU/RTU data in the transmission process, the use of such devices are in the operator intranet, the external network can not affect the data transmission. However, the use of private network services to operators to handle the special network card, high cost and processing cumbersome, for some application industry has limitations, price is not high. In addition to the special network business, what methods can guarantee the security of DTU/RTU data transmission? Here provides a more feasible solution, that is, using Xiamen for the independent research and development of the WCTU Wireless acquisition transmission terminal, WCTU wireless device integration of a variety of encryption protocols to encapsulate data, to ensure the security of user data transmission, the function is simple and easy to use, and the use of high value.

Xiamen for that Dtu/rtu is mainly used in the Internet of things communication industry, a wireless data transmission terminal, by using China Mobile, China Unicom, the Chinese telecommunications network to provide users with wireless long-distance data transmission function. Xiamen for that dtu/rtu the use of high-performance industrial-grade 32-bit processor as its hardware platform to ensure that the equipment stable, reliable, efficient work. Using stable embedded real-time operating system as its software support platform, support AES, DES, 3DES and other encryption methods, protect user data transmission security.
