Abstract

The invention belongs to the technical field of Internet of Things and information security, and discloses a general accurate access control technology for massive heterogeneous Internet of Things equipment of the Internet of Things. Comprising the following steps: designing a universal access verification control mechanism of the Internet of Things equipment in a manner of combining an asymmetric encryption algorithm with user feature information; introducing a Scode as a general data format of intra-domain node information interaction, so that the data is effectively prevented from being stolen or attacked while the efficient transmission of the data among the nodes in the domain is ensured. The problems of open port requirements and authority coarseness of the current massive heterogeneous Internet of Things equipment can be solved; and the problems of general accurate access control of external communication and internal resources of the equipment and effective prevention of unauthorized access are solved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things and information security, and specifically relates to a general and precise access control system and method for massive heterogeneous Internet of Things devices in the Internet of Things. Background technique [0002] Precise access control technology for IoT devices is an important prerequisite for a safe and reliable smart city. At present, open ports and unauthorized access are common problems in IoT devices, which not only make normal behavior difficult, but also expose devices to threats of attacks all the time, and existing solutions based on firmware and permission control are difficult to balance efficient communication Conflict between requirements and comprehensive access control. Therefore, in view of the current massive heterogeneous IoT device open port requirements and coarse-grained permissions, how to overcome the universal and precise access control of external co...
