Data encryption technology in computer network information security
KONG Dewu;Henan College of Industry & Information Technology;
Network information security affects the application and promotion of information technology,and may also cause commercial or economic losses. Based on this,this paper takes the threats of current computer network information security as an entry point,and make a systematic research on channel security threats,node security threats and computer security threats. After that,the paper analyzes the feasible data encryption technology,and gives the communication process encryption,node encryption,and comprehensive encryption defense mechanism for practical problems. Finally,the feasibility of the simulation experiment is demonstrated. The experiment is carried out in the computer environment by the parameter simulation method,which provides reference for the follow-up work by simulating different threat forms.
