Internet of Things data control method and device based on security authentication

Abstract

The invention discloses an Internet of Things data control method and device based on security authentication. The method comprises the steps that: the identity authentication of a local security authentication database is carried out when an instruction obtaining terminal needs to obtain an instruction, and an identity authentication request is transmitted to a security authentication layer of a cloud; the instruction obtaining terminal firstly receives identity authentication passing information of the local security authentication database, acquires sensing data of a sensing node, and temporarily stores the sensing data in a local storage unit; a security authentication layer judges whether the instruction obtaining terminal passes authentication or not; if yes, authentication is passed; a secure transmission channel with the cloud is established after authentication; and the instruction obtaining terminal transmits the data temporarily stored in the local storage unit to the cloud and acquires the control instruction from the cloud. After the local identity authentication is passed, the sensing data is acquired, and the identity of the acquired sensing data is also authenticated, so that the problem of security management of the sensing data, the control instruction and the instruction obtaining terminal is solved.

Description

technical field [0001] The invention belongs to the field of secure Internet of Things, and in particular relates to a security authentication-based Internet of Things data control method and device. Background technique [0002] The Internet of Things is an important part of the new generation of information technology. As the name suggests, the Internet of Things is "the Internet of Things Connected". This has two meanings: First, the core and foundation of the Internet of Things is still the Internet, which is based on the Internet. The extension and expansion of the network; second, its client end is extended and extended to any object and object for information exchange and communication. Therefore, the definition of the Internet of Things is: through radio frequency identification, infrared sensors, global positioning systems, Information sensing equipment such as laser scanners, according to the agreed protocol, connects any object to the Internet for information exch...
