Study on the DDS Network Information Security Technology

Abstract:

The paper firstly analyzes security and stability existed in the DDS network, and then finds that present DDS regulations cannot guarantee information’s confidentiality and integrity when facing an attack. Based on this, the paper puts forward a core thought of data analysis. According to the draft of DDS information security regulation, the paper analyzes information security threats that the DDS system must face, provides corresponding information security strategies in accordance with data granularity and operation means, and designs and realizes an information security model based on DDS. The security model there into is divided into three levels: boundary security, transmission security and data application security of fine granularity. At the same time, the paper also analyzes several important elements which influence DDS network security in detail, and then designs again the data-centered publication/subscription model. Finally, through the model testing by a lot of experiments, the experimental results show that: the model not only largely improves security of DDS network information, but also has already promoted stability and reliability of data transmission process.
