Study on Secure System Architecture of IOT

This paper first gives the basic concept and the construction of IOT,and analyzes the security problems and requirements of the IOT currently.In order to reduce the security risks of IOT,on basis ofBased on traditional system architecture of IOT,a secure system architecture,by adopting effecive security measures between the users,things and the information centers,is constructed,thus to reduce the security risk of IOT.Then it describes in detail its components,including its implementation principle of certification,encryption and access control mechanism.The secure system architecture of IOT can protect thecould provide effective security protection of IOT information transmit transmission and access,and then thus effectively improve the overall security level of IOT effectively.
