Research Of Information Security For Network Systems Based Delta Modulation

According to the growing complexity of network security vulnerabilities, system of information security is becoming more and more important. The delta modulation is the technique with simple structure and low cost in transmitting digital communication system. Because the technology of delta modulation system has some bug, people think a lot of methods of revised delta modulation system to improve the security of network systems and encrypt data transmission process to prevent malicious program steal information in network. Combining cloud-calculation technology and creating cloud security server center, it is a effective way to kill virus program establishing security fields. The people can solve effectively the problem on security of network system with delta modulation in first time.This paper introduce delta modulation system theory and its modified model, explain dynamics characteristic of Sigma - Delta modulation system. Using the existing network encryption technology and cloud safety management, this paper expounds the system based on the modified modulation system with delta modulation,construct its information security mechanism, strengthen feedback of network system,find the effect of its safety factors about network security, build the solution to network information safety measures.The feasibility of using new technology -- cloud calculation technology and high-level programming language constructs the network information system. The data testing can enhance the information security and find problems to put forward a feasible scheme in order to promote its economy measure.
