Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
Embodiment one
The present embodiment provides a kind of wireless networking verification methods of digital certificate formula, as shown in Figure 1, including step：
S11. the information of receiving terminal apparatus is sent wireless network request and terminal device；
S12. corresponding digital certificate information is generated according to the information of the received terminal device and is added with private key
It is close；
S13. receiving terminal apparatus send digital certificate authentication information and be decrypted with public key；
S14. judge whether the digital certificate authentication information of the decryption is consistent with corresponding digital certificate information, if one
It causes, then to the terminal device open network permission.
It further, further include step before step S12：
Judge whether the terminal device is trusted device according to the information of the received terminal device, if so,
Starting step S12.
Further, step S12 further includes step：
The digital certificate information of the generation is sent to terminal device.
Digital certificate is the volume of data for indicating network user identity information, and it is each to be used to the identification communication in network communication
The identity of side.Digital certificate uses public-key cryptosystem, i.e., is encrypted, decrypted, each user using a pair of matched key
Possessing one is only the private cipher key (private key) grasped in person, is encrypted and is signed with it；Possess simultaneously another public
Key (public key) simultaneously can be with external disclosure, for decrypting and verifying signature.When sending a classified document, sender uses private
Key is to data encryption, and recipient is decrypted using public key, in this way, information can arrive at the destination safe and punctually,
Even if being intercepted and captured by third party, due to lacking corresponding public key, can not be decrypted.
Terminal device can only carry out the transmission of Wi-Fi data with wireless router only by the password of input SSID, can not
Forwarded is carried out using wireless router networks, it is necessary to by further verifying.When terminal device networks for the first time, when wireless
After router receives the wireless networking request of terminal device transmission and the information of terminal device, first according to the letter of terminal device
Breath judges whether the terminal device is trusted device, if it is, being specific to the end according to the generation of the information of the terminal device
The digital certificate of end equipment, the digital certificate are made of a lot of character, represent the identity and qualification of terminal device, and will
The digital certificate of generation carries out encryption using the private key of wireless router and is sent to terminal device.
Wireless router can assist the public and private key of installing terminal equipment when terminal device proposes networking request for the first time, this is public and private
Key is the public and private key of terminal device, and the data of transmission are encrypted convenient for terminal device.When terminal device receive through
It crosses the digital certificate of the private key encryption of wireless router and is successfully installed after public and private key, wireless router can then be set to terminal
Preparation send digital certificate authentication order, for example, wireless router sends order " 4 be character after verifying digital certificate ", the order
It is sent to terminal device by the private key encryption of wireless router, the public key of terminal device wireless router is decrypted to obtain
Command context, and verification information is replied to wireless router according to the content of order, such as terminal device replys " 7e02 ",
" 7e02 " is sent to terminal device by the private key encryption of terminal device.Wireless router receives the number of terminal device reply
It after certification authentication information, is decrypted using the public key of terminal device and is verified content, then verifying content is counted with corresponding
Word certificate information compares judgement, if unanimously, to the terminal device open network permission.
Further, step S14 specifically includes step：
Whether each for judging the digital certificate authentication information of the decryption is each with corresponding digital certificate information
Position is consistent, if unanimously, to the terminal device open network permission.
For wireless router after receiving the digital certificate authentication information of terminal device reply and successful decryption, being will be digital
It is all consistent compared with each bit digital of certification authentication information carries out one by one with each bit digital of corresponding digital certificate information
Afterwards, just to the terminal device open network permission.
For example, the digital certificate authentication instruction that wireless router is sent is " 4 characters after verifying digital certificate ", terminal is set
The standby digital certificate authentication information replied is " 7e02 ", and wireless router then demonstrate,proves the number of this verification information and itself storage
4 characters compare after letter breath, all consistent, then wireless router is to the terminal device open network permission.
Correspondingly, a kind of wireless networking verifying system of digital certificate formula is also provided, as shown in Fig. 2, including：
First receiving module 11, the information for wireless network request and terminal device that receiving terminal apparatus is sent；
Generation module 12, for generating corresponding digital certificate information according to the information of the received terminal device；
