Embodiment Construction

[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] Such as figure 1 Shown is a schematic structural diagram of an embedded device provided by an embodiment of the present invention, the embedded device includes an encryption chip 10 and a main control chip 20, wherein:

[0049] The encryption chip 10 is used to burn the key for decrypting the upgrade program in its OTP area in advance, and cooperate with the main control chip to complete identity identification.

[0050] Specifically, the encryption chip 10 includes an OTP (One-time Password, dynamic password) area, which is used to store the ke...

Abstract

The invention discloses a method and system for remote automatic upgrading of embedded devices, which belong to the technical field of embedded devices. Download the upgrade compressed package from the file server; decompress the upgrade compressed package; execute the identity recognition executable program in the upgrade package to identify to obtain the key of the upgrade program file; decrypt the upgrade program file according to the key and perform the upgrade. By adopting the embodiment of the present invention, a double encryption mode is added, so as to realize safe and convenient remote automatic upgrading.

Description

technical field [0001] The invention relates to the technical field of embedded devices, in particular to a remote automatic upgrade method and system for embedded devices. Background technique [0002] With the continuous development of computer technology and network technology, embedded devices are widely used in various fields, and network-type embedded devices are more popular because of their convenience. All kinds of embedded devices emerge in endlessly, and the functions are more powerful, and the software is more and more complex. Therefore, software problems are inevitable, and system upgrades have become an indispensable function. Currently, there are two ways to implement remote upgrade of embedded devices: [0003] Method 1: Semi-automatic. In this method, manual operation is required before the device obtains the upgrade package from the Internet and then upgrades. This method is relatively safe but not intelligent enough and requires human intervention. ...
