and the burning module is used for entering a burning upgrading process after the identity is confirmed.
The firmware batch burning scheme has the roles of finished equipment, upgrading software and a cloud end. The upgrading process is mainly divided into two parts of identity authentication and burning upgrading. Both parts need to encrypt the transmitted data to ensure safety.
First, the cloud part needs to configure firmware information required by firmware upgrade, such as firmware upgrade files, firmware version information, verification information, encryption keys and the like. Meanwhile, the cloud end needs to provide an identity authentication account number for the software. And the software terminal acquires and downloads the cloud information to the local according to the account login condition and enters an upgrade preparation state. The software stores the upgrade firmware file in the local computer and enters a burning process according to the uplink information of the hardware lower computer.
And the lower firmware computer, namely a finished product to be burned, automatically releases a broadcast packet to the specific port number of the local area network after being electrified, wherein the content of the broadcast packet comprises a local Mac address, firmware version information and the like. And the upper computer software enters an identity confirmation process after monitoring the broadcast packet, and the confirmation mode is that information exchange is carried out between the upper computer software and the firmware according to account information provided by the cloud. Through an interaction flow which is agreed in advance, the firmware acquires necessary information returned by the cloud end through the upper computer, and then an encryption key is calculated and generated under the comprehensive information of the cloud end and the firmware, wherein the generated encryption key is used for a subsequent burning and sending packet, and the key is not forwarded through software, so that the security of the key is ensured. In the identity authentication stage, the communication with the firmware lower computer adopts a CBC mode in an AES256 encryption mode, and a secret key needs to be agreed in advance.
And after the encryption key is obtained, the identity authentication process is ended, and a burning upgrading mode is entered. And the encryption key used in the burning upgrading mode is encrypted and decrypted by adopting the encryption key calculated by the firmware in the identity authentication stage. It is ensured that each packet of data is sent encrypted. The encryption mode used here is an AES256 CTR mode, which has a high encryption speed and can ensure the upgrading speed on the premise of ensuring the information security.
The main working contents and the flow of the upper computer of the software system are as follows:
in the identity verification stage, necessary burning information, such as an upgrade firmware file, firmware version information and the like, is acquired through an account number provided by a cloud. And meanwhile, receiving an identity authentication broadcast packet issued by a lower computer of the local area network broadcast data receiving firmware. And determining whether the updating is needed according to the Mac address, the firmware version information and the like of the broadcast packet, and entering an identity authentication process if the updating is needed. And sending the firmware information to the cloud end, and returning a verification result and generating a key parameter by the cloud end. After receiving the data, the software sends the information to the firmware in an encryption mode through a synchronous communication protocol agreed in advance. The firmware returns to the cloud computing encryption key parameters for the cloud computing encryption key, and meanwhile, the key is sent to the software upper computer for subsequent communication encryption. The firmware generates an encryption key according to the effective information obtained by the identity authentication, at the moment, the software upper computer and the firmware lower computer both obtain the effective encryption key, and meanwhile, the key is not transmitted between the software upper computer and the firmware lower computer, so that the safety of data is ensured.
And after the identity authentication stage is finished, entering a burning upgrading stage. In the burning upgrade stage, according to the firmware upgrade file acquired by the cloud, file check information, such as CRC32, is sent to the firmware in advance, so as to check whether the file is burned correctly in the subsequent process. And when entering a state of being prepared for upgrading, the software carries out sub-packet encryption on the firmware file data and sends the data to the firmware packet by packet. Meanwhile, whether the data packet is correctly transmitted needs to be checked, and if packet loss occurs, retransmission needs to be performed. And after the firmware receives all the data packets, calculating a CRC32 value, and considering that the burning file is successfully sent.
Compared with the prior art, the method has the following beneficial effects:
wireless communication can be used by adopting a UDP (user Datagram protocol) communication mode, and assembled finished products do not need to be damaged, so that the rework cost is saved, and the time is saved. Meanwhile, the broadcasting packet can be sent by electrifying the router in a local area network broadcasting packet sending mode, network port setting in a TCP mode is not needed, burning can be carried out by using a common router, and setting difficulty and equipment cost are saved.
