Research And Application Of Multi-level Self-Adaptive Information Security Transmission Model

Sensor network is a set of sensors to form an autonomous network,which aims to percept and process the information of objects in a geographic area with a cooperation manner in order to obtain and publish the information to observers.The prospect of sensor network is very wide,mainly applied in military, environment, health,family and other business fields.With the extensive applications of sensor network, security issues are becoming more and more important and have attracted interest of more and more researchers.This paper first introduces applications,development of sensor network and major consideration of sensor network security issues.Later, according to the requirements of sensor network characteristics and internet information publications,we propose a novel security model,which is based on the analysis of the resource consumption of sensor network sink node and internet web servers.The model considers the power consumption of sensor network,network conditions,computing power, multi-system synchronization,data transfer and other issues.It also considers the adaption to sensor network hardware features to meet the demand for information classification, specifically quantifying the complexity of the algorithm in range of(0,1),whereas 0 means the lowest complexity of the algorithm, and 1 meas a maximum algorithm complexity. Meanwhile, the model carries out the same strategy to deal with the tasks in order to group the security service. The model not only fully guarantees the security of information transmission,but also satisfies the sensor network computing power and energy constraints.Then,we have carried out rigorious communication protocol simulations to prove the validity and reliability of the model.Finally, according to definition of secure transmission protocol,we release a SDK of seucrity protocol for the implementation of web services.
