Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The user enters a web address of http at the browser client and then connects to 443 port of the server. The server side adopting the http protocol is provided with a set of digital certificates, the digital certificates can be made by the user himself or applied to an organization by the user, the difference is that the certificates issued by the user himself can be continuously accessed only by the client side through verification, and a prompt page cannot be popped up when the certificates applied by a trusted company are used. A digital certificate contains a public key, a private key, an authority that issued the certificate, and a certificate validity period for the digital certificate.
The server transmits the digital certificate to the browser client, and the browser client verifies whether the digital certificate is valid, such as an issuing organization, a certificate validity period and the like. If an exception is found, a warning box is popped up to prompt that the certificate has a problem. If the verification is passed, the browser client generates a random value; and then encrypting the random value by using the public key, sending the encrypted random value to the server, decrypting by using a private key corresponding to the public key by using the server so as to obtain the random value transmitted by the browser client, and symmetrically encrypting the message information sent between the server and the client by using the random value. Thereby improving the security of the transmission of data.
According to the method and the system, the browser client is not used for a long time, so that the system clock has delay. When the browser client verifies the certificate validity period of the digital certificate, whether the local time is within the certificate validity period of the digital certificate is judged, and if the verification result shows that the local time is not within the certificate validity period, the local time is adjusted to be within the certificate validity period of the digital certificate, so that the certificate validity period of the digital certificate passes verification. After the digital certificate passes the verification, the browser client can generate a verification interface corresponding to the verification request, so that the wireless network connection of the browser client is facilitated.
Fig. 1 is a schematic flow chart of a network connection method according to an embodiment of the present application. A network connection method is applied to a browser client, and the browser client is in communication connection with a server; the method at least comprises the following operation flows: s101, sending a connection request of a secure network to a server; s102, receiving a verification request which is sent by a server and corresponds to the connection request; s103, verifying the local time according to the verification request to obtain a first verification result; if the first verification result represents that the verification fails, adjusting the local time to obtain the adjusted local time; s104, re-executing the verification of the local time based on the adjusted local time to obtain a second verification result; and S105, if the second verification result represents that the verification is passed, executing networking operation corresponding to the connection request.
In S101, based on a trigger of the user to the browser client, the browser client sends a connection request of the secure network to the server. Here, the secure network may be a wireless network based on the http protocol, or may be a wireless network encrypted based on another protocol.
In S102, the server sends a verification request corresponding to the connection request to the browser client according to the connection request, and the browser client receives the verification request. Here, the authentication request may be an authentication request based on an account and a password of the user logging in the network, or may be other requests for user authentication, which is not limited herein.
In S103, the local time is obtained from the RTC clock of the browser client, and the local time may be verified based on the time of the server, or may be verified based on a security certificate between the client and the server, which is not limited herein.
If the first verification result represents that the local time does not meet the preset condition, the first verification result is indicated to fail, and at the moment, the local time needs to be pushed backwards by a first preset step length, so that the local time is adjusted for the first time; wherein, the first preset step length is N years or M months, and N and M are natural numbers more than or equal to 1. If the first verification result represents that the local time meets the preset condition, the first verification result is passed, and at the moment, networking operation corresponding to the connection request needs to be executed. The first preset step length may also be N days or M weeks, where N and M are natural numbers greater than or equal to 1. Alternatively, the first preset step may be N hours or M minutes, where N and M are natural numbers greater than or equal to 1.
For example: the first preset step length is 1 year, the local time is 6 months and 1 day in 2019, and the adjusted local time is 6 months and 1 day in 2020 by gradually overlapping according to the first preset step length on the basis of the local time.
If the first preset step length is 8 months and the local time is 2019, 6, month and 1 day, gradually overlapping according to the first preset step length on the basis of the local time to obtain the adjusted local time of 2020, 4, month and 1 day.
If the first preset step length is 15 months and the local time is 6 months and 1 day in 2019, and the first preset step length is 3 months in 1 year, the years can be adjusted first and then the months can be adjusted when the first preset step length is gradually overlapped, namely 1 year is prolonged and then 3 months are prolonged on the basis of 2019, and the adjusted local time is 9 months and 1 day in 2020.
It should be noted that, in order to prevent an unexpected situation from occurring at the browser client due to too large adjustment range, an upper limit is usually set for the first preset step length.
In S104 to S105, the adjusted local time is verified again, so that a second verification result is obtained. And if the second verification result represents that the adjusted local time meets the preset condition, the second verification result is passed, and at the moment, the browser client executes networking operation corresponding to the connection request. If the second verification result represents that the adjusted local time does not meet the preset condition, the second verification result is failed; at the moment, the adjusted local time is continuously pushed backwards according to the first preset step length, so that the local time is adjusted for the second time; verifying the local time after the second adjustment, and if the local time passes the verification, executing networking operation; and if the verification is not passed, continuing to adjust the local time until the verification is passed.
Here, the preset condition may be an authentication time extracted from the digital certificate acquired by the server by the browser client. The preset condition may also be the time of authentication and the issuing authority.
For example, when the preset condition is the verification time, the browser client acquires a digital certificate from the server according to the verification request, then acquires a certificate validity period from the digital certificate, takes the certificate validity period as the verification time, and finally verifies the local time by judging whether the local time meets the verification time.
When the preset conditions are the verification time and the issuing mechanism, the browser client acquires the digital certificate from the server according to the verification request, then extracts the certificate issuing mechanism from the digital certificate, firstly judges whether the issuing mechanism is wrong, if the issuing mechanism is wrong, acquires the certificate validity period from the digital certificate, takes the certificate validity period as the verification time, and finally judges whether the local time meets the verification time, so that the local time is verified.
According to the method and the device, a browser client sends a connection request of a secure network to a server, receives a verification request which is sent by the server and corresponds to the connection request, and then verifies local time according to the verification request to obtain a first verification result; if the first verification result represents that the verification fails, adjusting the local time to obtain the adjusted local time; finally, based on the adjusted local time, the verification of the local time is executed again to obtain a second verification result; and if the second verification result represents that the verification is passed, executing networking operation corresponding to the connection request. Therefore, the network can be automatically and effectively connected, the problem that the network connection of the electronic product is not good due to the fact that the local time of the electronic product is inconsistent with the network time because the electronic product is not used for a long time in the prior art is solved, and the networking experience of a user is improved.
As shown in fig. 2, a schematic flow chart of a network connection method according to another embodiment of the present application is shown. The embodiment is further optimized on the basis of the previous embodiment. A network connection method is applied to a browser client, and the method at least comprises the following operation flows: s201, sending a connection request of a secure network to a server; s202, receiving a verification request which is sent by a server and corresponds to the connection request; s203, verifying the local time according to the verification request to obtain a first verification result; if the first verification result represents that the verification fails, adjusting the local time to obtain the adjusted local time; s204, based on the adjusted local time, re-executing the verification of the local time to obtain a second verification result; s205, if the second verification result represents that the verification passes, generating a verification interface corresponding to the verification request; s206, if the second verification result represents that the verification fails, the local time is continuously pushed backwards according to the first preset step length to obtain the adjusted local time, the verification step is executed until the verification is passed, and a verification interface corresponding to the verification request is generated; s207, based on the trigger of the verification interface verification information, sending user verification information corresponding to the verification request to the server side, so that the server side can execute networking operation corresponding to the connection request based on the user verification information.
The specific implementation processes of S201, S202, S203, and S204 are similar to those of S101, S102, S103, and S104 in fig. 1, and are not repeated here.
In S205 to S207, the verification interface is a verification interface based on the user identity information, for example: the authentication interface may be an interface of a user login account and a login password. Then, based on the triggering of the user to the interface of the login account and the login password, generating user authentication information; the browser client sends user authentication information corresponding to the authentication request to the server; and the server verifies the identity of the user according to the user verification information, and if the user identity verification passes, the server sends networking success information to the browser client.
Therefore, in the embodiment, based on the verification result of the browser client to the local time, the local time is adjusted until the local time passes the verification, and a verification interface is generated; therefore, the local time of the browser client is adjusted to be within the validity period of the certificate. Then based on the interaction between the browser client and the server, the server receives the user verification information sent by the browser client, verifies the user verification information and finally performs networking based on the verification result; therefore, the network of the browser client can be safely and effectively connected, and the reliability of network connection is improved.
As shown in fig. 3, a schematic flow chart of a local time verification method according to an embodiment of the present application is shown. The embodiment is further optimized on the basis of the previous embodiment. The local time verification method at least comprises the following operation flows: s301, acquiring a digital certificate from a server side according to the verification request;
s302, extracting verification time from the digital certificate; s303, verifying the local time by using the verification time to obtain a first verification result.
Specifically, after receiving a verification request sent by a server, a browser client acquires a digital certificate from the server based on the verification request; extracting verification time from the acquired digital certificate, then acquiring local time, and judging whether the local time is in the range of the verification time; if the judgment result represents that the local time is within the verification time range, determining that the first verification result passes; and if the judgment result represents that the local time is not within the range of the verification time, determining that the first verification result fails.
Here, the verification time generally refers to a time range. The certificate validity period of the digital certificate may be set as the verification time; the verification time may also be extracted based on the certificate validity period of the digital certificate, for example: the certificate validity period of the digital certificate is usually counted up to the year, month and day, and here, the year or month of the certificate validity period extracted from the digital certificate may be taken as the verification time. For example: the certificate validity of the digital certificate is from 2021/6/24 to 2026/1/25; the authentication time extracted from the digital certificate is 2021 to 2026 years; if the local time is 2019, 6, month and 1, the local time is not in the verification time range, so that the local time verification fails; if the local time is 2021/1/1 or 2021/6/1, the local time passes the verification since the local time is within the verification time range.
The digital certificate may be a CA digital certificate. The CA digital certificate ensures that the transmission signal between the browser client and the server is not intercepted or tampered, thereby ensuring the safety of information transmission between the browser client and the multi-server. The CA digital certificate is used for indicating the identity information of a certificate owner, the signature of a CA organization, a public key, a private key and the validity period of the certificate; the identity information is used for proving the identity of the certificate holder; the CA signature is used for ensuring the authenticity of the identity; the public key and the private key are used for encryption and decryption in the communication process, so that the safety of communication information is ensured; the certificate validity period is used to indicate the time at which the digital certificate is valid.
It should be understood that, in various embodiments of the present invention, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and the inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
In this embodiment, the browser client acquires the digital certificate from the server, extracts the verification time from the digital certificate, and then verifies the local time based on the verification time; therefore, the local time can be effectively verified, and the reliability and the accuracy of the verification result are improved.
The present embodiment will be described in detail with reference to specific application scenarios.
The network request mode is generally divided into two types, namely an Http request and an Http request, wherein the Http transmission belongs to plaintext transmission and is easily intercepted by a person and peeps contents in the plaintext transmission, and the Http is a secure hypertext transmission protocol with an SSL/TLS layer (secure socket layer) added on the basis of Http, and the transmitted contents are obtained by encryption, so the Http is a secure transmission.
Fig. 4 is a schematic diagram illustrating an http network connection process according to an embodiment of the present invention. The browser client and the server interact through an http communication protocol. Based on the triggering of the user on the network connection of the browser client, the browser client sends a connection request of an http network to the server, and the server sends a verification request for networking to the browser client based on the connection request. And the browser client acquires the CA digital certificate from the server according to the verification request, wherein the certificate validity period of the CA digital certificate is 2021/6/24-2026/1/25. The verification time extracted from the CA digital certificate in this embodiment is 2021 to 2026 years. And then the browser client acquires the local time and judges whether the local time is within the verification time range. And if the judgment result represents that the local time of the browser client is within the verification time range, determining that the local time passes verification, and generating a verification interface corresponding to the verification request, wherein the verification interface is used for displaying an interface for logging in a network account and a password. If the judgment result represents that the local time of the browser client is not in the verification time range, determining that the local time is not verified, and adjusting the local time in a mode of increasing year by year to obtain the adjusted local time; for example: the local time is 2019/6/1, and 1 year is added to the local time to obtain an adjusted local time of 2020/6/1. And then judging whether the adjusted local time is in the verification time range or not, if so, continuing to add 1 year to the adjusted local time to obtain 2021/6/1, judging whether the adjusted local time is in the verification time range or not, and if so, passing the characterization verification and generating a verification interface.
The browser client generates verification information based on the triggering of a user on a login network account and a password interface, the verification information is sent to the server, the server verifies the verification information, and if the verification result represents that the user identity verification passes, the browser client sends information that the wireless network connection is successful. Therefore, the http network can be safely and quickly connected, and the safety of network connection is improved.
