M2M功能架构与安全研究

摘要

M2M communication is seen as a form of data communication between entities that may have no human interaction, which is called machine-type communication. M2M is thought to be the main application of Internet of Things at present, the functional architecture and security problem of which is worthy of being stressed. Focused on this problem,European Telecommunications Standards Institute ( ETSI) has concluded the requirements on security. Besides,ETSI has designed a functional architecture in high level. The security of each model is further studied at last.%M2M通信被看作是一种不需要人际互动的机器之间的通信形式,通过通信网络传递信息从而实现机器与机器或人与机器的数据交换.M2M作为物联网在现阶段发展的主要存在形式,其功能架构和安全问题值得重视,文中主要围绕M2M功能架构与安全问题展开研究.针对此问题,欧洲电信标准化协会详细说明了M2M系统相关的安全需求,对机密性、完整性、身份认证以及授权批准进行了研究.此外ETSI还对M2M系统的功能架构进行了设计,提出了概要层的架构方案.最后对该功能架构中各部分涉及安全的模块作了进一步分析.
