Detailed description of the invention
By describing the technology contents of technical scheme, structural feature in detail, being realized purpose and effect, it is explained in detail below in conjunction with specific embodiment.
Present embodiments provide a kind of method that focus is provided on motor-car, it is applied between client, focus and certificate server, client is arranged on notebook, focus is arranged on motor-car, there is on motor-car voltage conversion unit, voltage conversion unit input is connected with motor-car power supply grid, the outfan of voltage conversion unit is connected with focus, voltage conversion unit is for powering to focus, focus is connected with the cellular base station module being arranged on motor-car, cellular base station module is used for connecting the Internet, and focus is for forwarding the internet signal of cellular base station module.The client so connecting focus can be surfed the Net by cellular base station module.Focus has unique first encryption method, i.e. the most different from other focuses, can carry out uniqueness association by the identification information of focus.Certificate server has the first decryption method corresponding with the first encryption method.
This method comprises the steps: that client forbids that other application programs communicate by being attached thereto WIFI module；Client is typically mounted in operating system, and operating system has other application programs, and operating system connects WIFI module, and application program can be communicated with external program by WIFI module.Client forbids that other application programs have multiple implementation by WIFI module communication, by intercepting the communication of other application programs and data packet discarding can be fallen, or an invalid route is set, thus by all of application program all by this routing forwarding, the communication of these application programs i.e. can be forbidden.
Client sets up connection by the WIFI module being attached thereto to focus；Client can show the focus that WIFI module searches, and after user clicks on focus, i.e. can set up with thermotropism point and connect.
Client sends and counts to focus at random；Client can generate a random number, this random number have various ways.Focus uses the first encryption method to be verified information after random number is encrypted computing；Checking information is i.e. the random number after encryption.
Focus replys checking information to client；Client sends focus identification information, checking information and counts to certificate server at random.Focus identification information can be mac address information or other information of focus, if other information, can send focus identification information together to client by focus focus replys checking information to client when.
Certificate server obtains first decryption method according to focus identification information；After certificate server uses first decryption method to be decrypted checking information and compare with random number and obtain authentication result；Certificate server replys authentication result to client；Client judges whether authentication result is passed through.
If passed through, then other application programs are allowed to communicate by being attached thereto WIFI module；If do not passed through, then disconnect the connection between focus.So, random number owing to not knowing encryption method, then can not be encrypted and obtain correct checking information by the focus falsely used, and natural cannot certification on certificate server is passed through.Then client just can disconnect and the connection of the focus falsely used, thus avoids the connection of illegal focus.
Focus in order to avoid falsely using directly transmits legal authentication result to client, in certain embodiments, unique second encryption method is had between certificate server, client has second decryption method corresponding with the second encryption method, wherein: when client sends authentication information to certificate server, client sends client identification information to certificate server；After certificate server obtains authentication result, obtaining the second encryption method according to client identification information, use the second encryption method to be encrypted authentication result and random number, the authentication result after then certificate server replys encryption is to client；Client judges, when whether authentication result is passed through, to be decrypted authentication result initially with the second decryption method, it is judged that whether random number is the most correct passes through with authentication result；If random number is correct and authentication result is passed through, then other application programs are allowed to communicate by being attached thereto WIFI module；Otherwise, then the connection between focus is disconnected.So, authentication result is also the data of encryption, if the focus falsely used at will sends other legal authentication results, does not then encrypt through the second encryption method due to this authentication result, then cannot decipher and obtain correct random number and authentication result.Thus avoid the focus falsely used and arbitrarily send other legal authentication result to client, and cause the problem that client connects.
Certainly, as long as client is not by being the WIFI module acquisition that is authenticated result, just can be greatly improved the correctness of authentication result, as passed through mobile phone radio frequency module (2G, 3G, 4G communication module etc.), client sends and receives the information of certificate server and includes: client sends and receive certificate server information by mobile phone radio frequency module.WIFI pattern when so the focus owing to falsely using is carried out, and mobile phone radio frequency module cannot be falsely used, then client is legal authentication result from the authentication result that mobile phone radio frequency module gets.
Many times, the focus falsely used and legal focus are in a place, for this illegal in the case of, need to remind in time user.Then before this method starts, further comprise the steps of: client judges around whether there is the focus that two or more ssid information is identical with mac information, if it has, then point out this focus.Prompting can be carried out by dialog box or by the way of being highlighted, and user one sees such situation, will vigilance relatively when of connection.
In order to avoid connecting illegal focus elsewhere, present invention additionally comprises following steps: detection focus signal intensity, after focus signal intensity is less than preset value, disconnection and the connection of focus also delete hot information.After deleting hot information, the equipment installing client just cannot connect this hot information automatically, thus ensures safety.
