Abstract

The invention belongs to the technical field of the Internet of Things and information security, and discloses a general precise access control technology for massive heterogeneous Internet of Things devices in the Internet of Things. The universal access verification of Internet of Things devices is designed by using an asymmetric encryption algorithm combined with user characteristic information. control mechanism, and the introduction of S code As a general data format for information exchange between nodes in the domain, it can ensure the efficient transmission of data between nodes in the domain while effectively avoiding data theft or attack, and can cope with the current massive heterogeneous Internet of Things device open port requirements and coarse-grained permissions. Breakthrough Universal and precise access control of external communication and internal resources of the device and effective prevention of unauthorized access.

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...
