The firmware information in this embodiment refers to a program written in EROM (erasable read only memory) or EEPROM (electrically erasable programmable read only memory). Specifically, the device driver stored in the device is used, and the operating system can realize the operation of a specific machine according to the standard device driver through firmware. In this embodiment, the first firmware information is obtained by encrypting the original firmware information, and the second firmware information is obtained by backing up the first firmware information, so that when the first firmware information is damaged, the electronic device can be started by using the second firmware information, thereby ensuring normal starting of the electronic device. And the first firmware information or the second firmware information is verified before the electronic equipment is started, so that the safety of the electronic equipment is ensured, and the electronic equipment is prevented from being attacked by hackers.
A second embodiment of the present invention provides a starting method for an electronic device, as shown in fig. 2, including the following steps:
step S201, judging whether the embedded controller stores the first firmware information;
in the specific implementation process of this step, whether the first firmware information is stored in the embedded controller is confirmed through a predetermined boot loader.
Step S202, when the embedded controller is judged not to store the first firmware information, acquiring the first firmware information from the preset position, and storing the first firmware information to the embedded controller;
the predetermined location described in this embodiment refers to the BIOS firmware. Specifically, before step S201, the first firmware information is stored in the BIOS firmware in advance.
Step S203, verifying the first firmware information stored by the embedded controller by using the embedded controller;

In this embodiment, before step S201, when the first firmware information is stored in the BIOS firmware in advance, the second firmware information and the predetermined encryption algorithm are stored in the BIOS firmware at the same time.
In the embodiment, the second firmware information is obtained by backing up the first firmware information, and when the first firmware information is damaged, the electronic equipment can be started by using the second firmware information, so that the normal starting of the electronic equipment is ensured.
A third embodiment of the present invention provides a starting method for an electronic device, including the following steps:
step S301, calculating original firmware information by using a server according to a preset encryption algorithm to obtain a signature;
in this step, the original firmware information is the "driver" that can drive the device without encryption. In this step, the server is used to calculate the original firmware information according to the preset encryption algorithm key, so as to obtain the signature S.
Step S302, based on the original firmware information and the signature, encoding and encrypting are carried out by using a preset software encryption method, and the first firmware information is obtained;
after the signature S is obtained in this step, the first firmware information can be obtained by combining the signature and the original firmware information. In order to prevent the first firmware information from being cracked, the combined firmware information needs to be encrypted by encryption software after combination. Specifically, the combined firmware information is divided to obtain a plurality of information blocks, and then each piece of information is encoded to obtain the first firmware information.
Step S303, copying the first firmware information to obtain second firmware information;
the implementation can perform backup on the first firmware information to obtain the second firmware information after performing encryption twice on the original firmware information to obtain the first firmware information.

In this step, the predetermined location may be BIOS firmware. Namely, the first firmware information, the second firmware information and the preset encryption algorithm key are stored in the BIOS firmware.
Step S305, judging whether the embedded controller stores the first firmware information;

In the step, specifically, first firmware information is obtained from a BIOS, and a preset encryption algorithm key is obtained at the same time; and then decoding each information block by using encryption software, combining the decoded information blocks according to the position sequence to obtain combined firmware information, and finally storing the combined firmware information to the embedded controller. I.e. the combined firmware information comprises the original firmware information and the signature S.
Step S307, verifying the first firmware information stored by the embedded controller;
in the specific implementation process of this step, after the first firmware information is decoded, the combined firmware information obtained is verified. The specific verification process is as follows: the embedded controller calculates original firmware information in the combined firmware information by using a preset encryption algorithm key acquired from the BIOS to obtain a first check value S ', compares the first check value S' with a signature S in the combined firmware information, verifies that the original firmware information is correct (i.e., verifies that the first firmware information is correct) if the first check value S 'is the same as the signature S, and verifies that the original firmware information is wrong (i.e., verifies that the first firmware information is wrong) if the first check value S' is different from the signature S.
Step S308, when the first firmware information is verified to be correct, starting the electronic equipment based on the first firmware information; and when the first firmware information is verified to be wrong, obtaining the backed-up second firmware information from a preset position, storing the second firmware information to the embedded controller so as to verify the second firmware information by using the embedded controller, and starting the electronic equipment based on the second firmware information under the condition that the second firmware information is verified to be passed.
In this step, when the first firmware information is verified to be correct, the electronic device is specifically started based on the original firmware information in the first firmware information. When the first firmware information is verified to be wrong, specifically, the preset encryption algorithm key is obtained from the second firmware information in the BIOS; then, decoding each information block of the second firmware information by using the encryption software, and combining the decoded information blocks according to the position sequence, thereby obtaining the combined firmware information corresponding to the second firmware information, finally storing the combined firmware information to the embedded controller, and then verifying the second firmware information, wherein the specific verification process is the same as that of the first firmware information, namely: the embedded controller calculates original firmware information in the combined firmware information by using a preset encryption algorithm key acquired from the BIOS to obtain a second check value S ', compares the second check value S' with the signature S in the combined firmware information, verifies that the original firmware information is correct (i.e., verifies that the second firmware information is correct) if the two are the same, and verifies that the original firmware information is wrong (i.e., verifies that the second firmware information is wrong) if the two are different.
In this embodiment, after verifying that the second firmware information is correct, the method further includes overwriting the first firmware information in the BIOS firmware with the second firmware information stored in the BIOS firmware. In this embodiment, the BIOS firmware is specifically stored in sprom of the CPU.
In this embodiment, by signing the original firmware information in the first firmware information and the second firmware information, it can be verified whether the original firmware information is correct, so that the security of the device can be ensured, and hacking can be prevented.
