Abstract

The invention provides a serial communication controller based on a security CPU chip, and relates to the technical field of serial communication control. The technical problem that the serial communication data transmission is unsafe, resulting in data loss and theft in the prior art is solved. The serial communication controller provided by the invention comprises a security CPU controller, anda level conversion interface module, a serial parallel conversion module, an input module and an output module, which are connected to the security CPU controller, wherein the serial communication controller further comprises a serial communication module connected with the level conversion interface module, and a power circuit. The serial communication controller provided by the invention encrypts and decrypts data, thereby ensuring the security of the transmitted data, preventing data loss and theft caused by network attacks, having the advantages of being practical and convenient, and alsobeing able to improve the working speed and improve the working efficiency.

Description

technical field [0001] The invention relates to the technical field of serial communication control, in particular to a serial communication controller based on a safety CPU chip. Background technique [0002] With the development of computer networking and microcomputer graded distributed application systems, the function of communication is becoming more and more important. Communication refers to the information transmission between the computer and the outside world, including the transmission between computers, as well as the transmission between computers and external devices, such as terminals, printers, and disks. In the field of communication, according to the number of data bits transmitted each time in data communication, the communication methods can be divided into: parallel communication and serial communication. [0003] Serial communication refers to the serial transmission of data between the computer host and peripherals and between the host system and the...
