Detailed Description
For a better understanding of the above technical solutions, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The technical scheme of the invention mainly aims to solve the problems that whether the certificate in the wireless module is expired cannot be verified when the wireless module of the electronic equipment in the prior art has no built-in clock or the built-in clock fails, so that the electronic equipment cannot realize normal and effective communication when the electronic equipment communicates by using the expired certificate.
In one embodiment, the electronic device includes, but is not limited to, an air conditioning device, a purifier, a refrigerator, a water heater, a range hood, a dishwasher, and the like, and any device having a wireless module falls within the scope of the electronic device.
The certificate, specifically referred to as a digital certificate, is a file digitally signed by a certificate authority that contains public key owner information as well as a public key. The digital certificate can be used for the authentication of the electronic equipment and other equipment when the electronic equipment is communicated with the other equipment, and the authentication can be effectively and infallibly carried out on the network.
The real Time clock, rtc (real Time clock), is an integrated circuit. Real-time clocks can be used to provide accurate real-time to people or to provide an accurate time reference for electronic systems.
Such as but not limited to a wifi module.
Referring to fig. 1, fig. 1 is a flowchart illustrating an operation method of a wireless module according to an embodiment of the present invention. The operation method of the wireless module comprises the following steps:
step S11, when the wireless module can not determine the real-time clock, the real-time clock is obtained from the communication device through the first channel;
step S12, when receiving the real-time clock returned by the communication device, verifies whether the certificate in the wireless module expires according to the received real-time clock.
The communication device includes, for example and without limitation, a server, and may also include, for example, other terminal devices that communicate with the wireless module. The communication device may include a plurality of channels, such as a first channel and a second channel. A channel is in particular a communication channel for data transmission. Specifically, the first channel is, for example, an unencrypted channel, and the second channel is an encrypted channel.
In one embodiment, the wireless module may have a real-time clock and a built-in real-time clock, and both of the situations may cause the wireless module to be unable to determine the real-time clock. Therefore, in the first case, when the real-time clock is not present in the wireless module, the real-time clock is directly acquired to the communication device through the first channel. In the second case, when the real-time clock exists in the wireless module, the real-time clock built in the wireless module is firstly acquired, and when the real-time clock is judged to have a fault in the feedback information, the real-time clock is acquired to the communication equipment through the first channel.
And when the real-time clock is acquired, verifying whether the digital certificate in the wireless module is expired or not by using the real-time clock. In particular, in one embodiment, the digital certificate includes, in addition to key information, expiration information, such as an initial date and an expiration date. After the real-time clock is acquired, whether the digital certificate is expired or not can be judged according to the valid period information.
According to the operation method of the wireless module, the real-time clock is obtained by utilizing the communication equipment which is communicated with the wireless module, so that the verification of the digital certificate in the wireless module can be realized when the real-time clock does not exist in the wireless module or the real-time clock fails, the problem that the electronic equipment cannot realize normal and effective communication because the electronic equipment utilizes the expired certificate for communication is solved, and the effective communication of the electronic equipment is ensured.
Further, as shown in fig. 2, fig. 2 is a schematic flowchart of an operation method of a wireless module according to another embodiment of the present invention. In an embodiment of the present invention, the step S12 in the above embodiment further includes:
step S13, when the certificate in the wireless module is expired, the certificate is obtained from the certificate server, and the certificate returned by the certificate server is received;
step S14, when the certificate in the wireless module is valid, data transmission is performed through the second channel of the communication device based on the certificate.
When the wireless module uses the digital certificate for the first time, the wireless module needs to apply for the certificate server, and after the identity of the certificate server is verified, the wireless module issues the corresponding digital certificate. The digital certificate has a validity period, that is, the digital certificate is valid within the validity period, so that when the digital certificate is expired, the digital certificate needs to be updated to the certificate server again, and after the certificate server performs identity verification on the wireless module, a new digital certificate is issued to the wireless module.
If the certificate in the wireless module is not expired, the certificate is directly used for encrypting the data, the encrypted data is sent to other equipment through a second channel of the communication equipment, and the certificate is directly used for decrypting the data sent by the other equipment.
According to the technical scheme, the method and the device for updating the digital certificate timely update the certificate server when the certificate is expired according to the judgment of whether the certificate is expired, so that the problem that the electronic equipment cannot normally communicate due to the fact that the digital certificate is expired is avoided, and normal communication of the digital certificate is guaranteed.
Further, as shown in fig. 3, fig. 3 is a schematic flow chart of an operation method of a wireless module according to another embodiment of the present invention. In an embodiment of the present invention, the step S11 in the above embodiment further includes:
step S15, after the wireless module is turned on, the real-time clock is periodically determined to verify the certificate in the wireless module.
In order to ensure the continuous validity of the digital certificate in the wireless module, after the wireless module is started, the real-time clock, namely the current time, is periodically determined to verify whether the digital certificate in the wireless module is expired, and when the digital certificate is judged to be expired, the digital certificate is timely updated to the certificate server, so that the normal communication of the digital certificate is ensured.
In another embodiment, the wireless module may also obtain the real-time clock when digital certificate verification is required. For example, when the wireless module receives data to be sent to other devices or receives data sent by other devices, in order to ensure the effective use of the digital certificate, the real-time clock is acquired to verify whether the certificate in the wireless module has expired.
