In this paper, we introduced the characteristics of data transmission in the IOT environment, then on the basis of the performance of the SSL protocol, proposed the lightweight and high-performance LSSL approach to realize safe data transmission.

With the establishment of quick response mechanism for disaster relief logistics operations,emergency material distribution has assumed added importance in alleviating the damage of natural disasters.Emergency material is dynamic in its distribution process.In view of such property,the paper formulates the distribution decision-making model for emergency materials on the basis of feedback-control principles and analyzes its decision-making process in disaster relieving operations.

Once enlergency happened,the requirements for materials are numerous and complicated,the requirements are urgent and variational as well in.To impove the efficiency of emergency logistics,the rescuer need to classify the emergency materials.A novel method for emergency materials classification based on posterior probability support vector machine is proposed.The classification model for emergency materials is presented via PPSVM.This article took the materials importance;urgency and scarcity as the classified criterion,put the velues after being fuzzed as the input of PPSVM,selected the classification which is corresponding with the Max Posterior Probability as the output ,the results of the classification are obtained finally .Experimental results demonstrate that the proposed method is feasible,it can solve the problem of emergency materials classification effectively.

Focusing on the problems of the emergency materials support,the paper uses the idea of supply chain management to improve the emergency materials support system,introduces the connotation,characteristics and contents of the emergency materials supply chain and especially studies the essential aspects in the operation of SCM.
