| With the rapid development of cloud computing technology and Internet of things technology,more and more scenes require virtual resources and Internet of things terminals to work together to complete complex tasks.Combining with cloud computing technology and Internet of things technology,users can flexibly configure the resource management system to use,monitor and manage virtual resources and the Internet of things terminals.The combination and development of cloud computing technology and Internet of things technology further enhance the usability,flexibility,reliability and security of lightweight resource management system in virtual-real interconnection environment.However,due to the large number and variety of resources,the efficient and safe management of resources is facing with severe challenges.The core of the problem is that the resource management mechanism cannot meet the resource management needs in virtual-real interconnection environment,which leads to the problem of resource isolation and resource sharing.Specifically,the problem of resource isolation in virtual-real interconnection environment is that the current access control model and access control scheme cannot effectively isolate resources,and cannot guarantee the security of resources.Meanwhile,the problem of resource sharing in virtual-real interconnection environment is that the existing access control technology cannot achieve flexible data interaction among resources based on specific application scenarios.These problems seriously hinder the further integration of cloud computing technology and Internet of things technology,and affect the usability and security of the resource management system.In order to solve the problem of resource management in virtual-real interconnection environment,and satisfy the demand of resource isolation and resource sharing under virtual reality interconnection scenarios,this paper analyzes the existing access control technology,and proposes a MIXAC model in virtual-real interconnection environment combined with the characteristics of resources in virtual-real interconnection environment.Based on this model,we put forward a complete resource management scheme,design a lightweight resource management system in virtual-real interconnection environment and test it at last.The main contents of this paper are as follows.Firstly,this paper combines the needs of resource sharing and resource isolation in virtualreal interconnection environment.Based on the BLP model a more efficient and secure MIXAC model is proposed by adding related characteristics of resources in virtual-real interconnection environment and the environmental attributes under specific scenarios.Secondly,based on MIXAC model,this paper analyses the requirement of resource access control in virtual-real interconnection environment,designs a scheme for resource sharing and resource isolation,realizes the security management function of resource management system in virtual-real interconnection scenario with access control as the key point,and analyses the security and efficiency of the scheme.Thirdly,according to the resource management scheme in virtual-real interconnection environment,combined with the application scenarios of virtual-real interconnection and the current common technologies,access control is realized by user,resource and environment security information,and resource isolation and resource sharing are realized by the coordinated operation of system level and network layer.Finally,this paper achieves the lightweight resource management system,tests the functions of user and resource subjects,and tests the performance impact of resource management system on cloud platform.It proves that the lightweight resource management system can effectively and safely achieve resource isolation and resource sharing,resource management in virtual-real interconnection environment. |
