计算机网络信息安全中的数据加密技术

Data encryption technology in computer network information security

网络信息安全直接影响着信息技术的应用与推广,也可能带来商业或经济方面的损失.基于此,本文以当前计算机网络信息安全面临的威胁作为切入点,予以简述,包括信道安全威胁、节点安全威胁、计算机安全威胁等.在此基础上重点分析可行的数据加密技术,针对实际问题给出通信过程加密、节点加密、综合加密防御机制等内容.最后依据仿真实验论证其可行性,实验以参数模拟法在计算机环境下开展,通过模拟不同的威胁形式为后续工作提供参考.

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.
