Description
Technical field
The present invention relates to intelligent terminal remote upgrade technical fields, and in particular to one kind is realized embedded hard based on block chain
Part OTA upgrade-system and method.
Background technique
With the fast development of current Intelligent terminal for Internet of things, occur various types of intelligent terminals, such as intelligence in the market
Energy household electrical appliances, smart home, intelligent sound box etc., and most intelligent terminal all supports wireless (WiFi) function, to facilitate this
A little equipment networkings.Due to the upgrading of later product function or the reparation etc. of system safety problem, intelligent terminal software
Remote upgrade (OTA:Over-the-Air) its firmware under connected state is needed, to facilitate user and reduce intelligent terminal life
Produce the operation maintenance cost of manufacturer；There are following several common technology schemes at present:
(1) intelligent terminal production firm provides a fixed network service address, directly uploads and updates firmware, and is indefinite
Phase pushes OTA upgrading message to the intelligent terminal networked；Intelligent terminal opens automatically after comparing version number after receiving that message
Dynamic firmware upgrade procedure；
(2) user can be searched by the network service address for the fixation that intelligent terminal production firm provides and need to be upgraded most
New firmware software, and be downloaded to local, then it is triggered by the external interface (such as USB or serial ports) of intelligent terminal itself
Built-in firmware upgrade procedure；
(3) user applies APP by mobile terminal matched with intelligent terminal, is directly connected to firmware background server, finds
And download or push corresponding intelligent terminal firmware, reuse wireless or be locally-downloaded, then being pushed in a manner of importing needs to rise
The firmware of grade completes OTA upgrading.
Although existing technology can allow its intelligent terminal firmware of user's remote upgrade, have the disadvantage in that once raw
It produces manufacturer to decide not to safeguard the intelligent terminal firmware or production firm's break, user not only may lost its intelligence eventually
Firmware upgrade is held to the final opportunity of latest edition, the networking intelligent terminal not upgraded is made to be faced with various functional or safeties
Potential risk, it is often more important that, the third company of some malice or individual, it is easy to solid by establishing its imitated OTA
Part upgrade service continues as the intelligent terminal networked and carries out OTA upgrading, if intelligent terminal OTA firmware upgrade procedure lacks one
Fixed secure authentication mechanisms may make equipment occur maliciously being controlled after upgrading third party's firmware automatically and cause personal hidden
The major safety problems such as private leakage.
In view of this, being badly in need of improving existing intelligent terminal OTA upgrading scheme, intelligent terminal OTA upgrading is improved
Reliability and safety, prevent OTA firmware by third party malice distort.
Summary of the invention
The technical problem to be solved by the present invention is to existing intelligent terminal OTA upgrading scheme, it is easy by third party's malice
It distorts, and not can guarantee OTA firmware long continuance, the problem of reliability and safety difference.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that providing a kind of embedding based on the realization of block chain
Enter formula hardware OTA upgrade method, comprising the following steps:
