摘  要:网络通信信息的完整性和安全性对于用户来说越来越重要,为探究以硬件电路方式校验、加密网络通信信息,基于LPC1768芯片、AMS1117芯片、CH340G芯片和KSZ8041NL芯片,设计了数据校验加密电路、DC/DC电路、TTL转USB电路、以太网通信电路,开发了USB接口通信程序、数据校验程序、数据加密程序、以太网通信程序。以模拟北斗和通信信息为例,实现了对模拟信息的校验、加密、解密以及USB接口通信和网络通信测试工作。在整个过程中,保证了模拟信息的完整性、安全性,所设计电路具有一定的实际应用价值。Integrity and safety of network communication information are more and more important for users. To explore check and encryption of network communication information by the way of circuit,the data check and encryption circuit,DC/DC circuit,TTL to USB conversion circuit,Ethernet communication circuit were designed,and USB interface communication program,checking data program,encrypting data program,Ethernet communication program were developed on the basis of LPC1768 chip,AMS1117 chip,CH340G chip and KSZ8041NL chip. Through the simulation of BD and communication informa?tion,the check,encryption and decryption of simulation information,as well as the testing of USB interface communication and network communication were accomplished. In the whole process,integrity and safety of the simulation information were en?sured. Therefore,the circuit has a certain practical application value.
