Embodiment Construction

[0047] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0048] like Figure 1-Figure 4 As shown, the method of the DTU system with data encryption performance, including the encryption method, the encryption method runs on the sender, the encryption method includes:

[0049] Step 1-1: The sender first generates a random number not greater than 256, and uses this random number to obtain the cursor and password vector in the column of data in the password vector table to which the label consistent with the random number belongs. Just as the current cursor; the password vector table is used as a dynamic electronic codebook, the password vector table includes 256 columns of data, each column of data includes a label, a cursor and a password vector, and all labels are arranged in the password vector table as the first One row, all the labels are 256 integers from 1 to 256, all the labels are arranged in the first ...

Abstract

The invention discloses a DTU system with data encryption performance and a method thereof, which can realize data communication under protocols of SSL and TLS by adopting an OpenSSL software librarypackage and realize bidirectional identity authentication between a DTU and a server. The encryption and decryption processing can be automatically carried out in the DTU, extra encryption and decryption equipment is not needed, and the use, operation and maintenance cost is effectively reduced. The standard protocol obtained after the set ciphertext negotiation is conveniently applied to the implementation of the server. A user can define an encryption protocol by himself / herself according to the self-defined dynamic electronic password book.

Description

technical field [0001] The invention relates to the technical field of DTU, in particular to a DTU system and method with data encryption performance. Background technique [0002] Data transfer unit DTU (Data Transfer unit) is a wireless terminal device specially used to convert serial data into IP data or convert IP data into serial data for transmission through wireless communication network. Common DTUs, especially 4G DTUs are mostly Using the method of data transparent transmission, with the development of the Internet of Things (IoT), the requirements for data security are getting higher and higher, and the traditional DTU cannot meet this requirement. In order to realize data ciphertext communication, users have to use industrial Computers and additional ciphertext processing modules perform encryption and decryption processing, which makes the system structure complex and difficult to maintain, and also increases deployment and operation and maintenance costs. SUMM...
