Research On Secure Communication Mechanism Between Trusted Server And Cloud Computing Server Model

In recent years,with the development of Cloud Computing Technology,the secure problem it is facing becomes more and more serious.Trusted Computing Technology is an important technology which means using Trusted Computing Technology to support Cloud Computing for a safe environment.Current Trusted Computing architecture is mainly based on the Xen platform,by virtualizing the chip which is in the platform itself to protect the security of virtual machine,The communication mechanism between the trusted cloud computing server platform and the trusted server platform where the trusted chip is built using the trusted trusted chip is an important research problem;Moreover,inside of the cloud environment in the process of communication exits a number of cloud servers,how to conduct a reasonable dispatch between the multiple cloud servers' requests for communication,to improve the efficiency of communication between platforms is the key problem;Finally,the security in the process of communication is the foundation of communication between platforms and other Trusted Computing features.At present,in order to solve the main problems that trusted server platforms and Trusted Cloud Computing server platform models are facing,We can design a dedicated centralized management and security platform to ensure the safety of the security management module,this model deals with the implementation of communication mechanism,scheduling algorithm,security and other issues.At the same time,in order to improve the efficiency and protect the security of the platform,the function of the module is independent to other functional modules of the platform model.The communication mechanism between the platforms is based on the TCP/ IP protocol which is widely used in computer network environment,using TCP/ IP transport protocol to achieve the communication between platforms.The TCP/ IP protocol can guarantee the accuracy,validity and security of communication data between models.Therefore,the communication mechanism of the model platform is designed by using the communication data transmission method.Facing the problem that Cloud Computing environment has a huge number of Trusted Cloud Computing Servers corresponding to the same trusted server platform,the secure communication management module uses the reasonable queue scheduling algorithm to schedule the communication requests with different priorities.Due to the transmission and interaction of data between a trusted server and a lot of Trusted Computing Servers belong to one to many communication methods.So we need to use the appropriate scheduling method,according to the different priority queues,the priority is processed from high to low,after that,send the response data.It can not only guarantee the priority of the high priority request,but also provide the service for the low priority queue,so as to improve the overall efficiency of the communication system.At last,one of the most important aspects of communication between platforms is to ensure the security of communication.It helps to ensure the security of the whole platform model.Therefore,the security of communication is divided into two parts: remote authentication before communication begins and digital signature and data encryption algorithm for data transmission,guarantee the security,integrity and nonrepudiation of the communication between the models of platform,making the whole model in a safe environment for data processing.This paper presents a secure communication mechanism between Trusted Server platform and Trusted Computing Server platform,a series of solutions can meet the needs of communication between the platform model and security requirements.At the same time,it uses the reasonable queue scheduling algorithm to improve the efficiency of the platform,and puts forward some ideas for current Trusted Computing and Cloud Computing.
