Abstract

The invention discloses a bidirectional authentication method for OTA upgrade of Internet of Things equipment based on a block chain technology, and the method comprises the following steps that: the Internet of Things equipment or a module is internally provided with an equipment identifier before leaving a factory, and the equipment identifier is used as a unique identity identifier; an alliance chain is constructed, and the alliance chain comprises a plurality of service nodes and is used for providing OTA upgrade package downloading service of the Internet of Things equipment; for the Internet of Things equipment, when the Internet of Things equipment is networked and online for the first time, a hash value of an equipment identifier which is calculated by a hash algorithm and is programmed in an internal trusted storage space/Efuse is sent to a service node, and the Internet of Things equipment is linked to serve as an equipment evidence. The potential safety hazard in the OTA upgrading technical scheme of the existing Internet of Things equipment is solved, the safety and the reliability of the OTA upgrading process are ensured, and trust and two-way safety certification of the software upgrading package and the terminal equipment are ensured.

Description

technical field [0001] The invention relates to the technical field of computer software and hardware, in particular to a two-way authentication method for OTA upgrade of Internet of Things devices based on block chain technology. Background technique [0002] In the rapidly updating and changing Internet of Things market, the demand for new products is continuously iterated, so the demand for updating smart hardware devices has become unprecedentedly high, and devices are no longer like traditional devices that will not be changed once they are sold, so over-the-air (OTA) technology has become extremely important. The Internet of Things platform supports device firmware upgrades through OTA, which is the main means for smart devices to repair system vulnerabilities and achieve system upgrades, and provide users with better services through firmware upgrades. The OTA firmware upgrade function can not only update the firmware, but also reconfigure the modules and hardware re...
