Detailed description of the invention
Fig. 1 is the step block diagram of the mutual authentication method provided by the invention based on ciphering two-dimension code；
Fig. 2 is the functional block diagram of the two-way authentication system provided by the invention based on ciphering two-dimension code.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of mutual authentication method based on ciphering two-dimension code, comprising:
Step 1: accessed end discloses its first public key, and first public key is corresponding with the first private key of accessed end；
The first key pair for being encrypted and decrypted, i.e. the first public key are preset in the step 1, in accessed end
With the first private key, wherein first public key is for encrypting information, and first private key is for solving information
Information that is close, being encrypted by first public key, it is necessary to be decrypted by first private key.
Its first public key is converted to public key two dimensional code using two dimensional code algorithm by accessed end, by first public key with institute
The form for stating public key two dimensional code carries out disclosure in any public area such as the network platform, device screen or equipment surface, by accessing
End obtains the first public key of accessed end by the APP in terminal in a manner of barcode scanning from the public key two dimensional code, and described the
One private key is then saved privately by accessed end and is not disclosed outward.
Step 2: access end is after obtaining first public key, using first public key to needing to be sent to accessed end
The first information and itself the second public key encrypted, form the first ciphering two-dimension code, and will first two dimensional code transmission
To accessed end, second public key is corresponding with the second private key of access end；
In the step 2, access end obtains accessed end from the public key two dimensional code in a manner of barcode scanning by the APP in terminal
The first public key, and be applicable in first public key and the first information for needing to be sent to accessed end encrypted, and by described
The information of first public key encryption can only can be just decrypted by first private key, therefore even if the first ciphering two-dimension code
It is stolen, due to lacking first private key, the first information in the first ciphering two-dimension code will not leak, greatly
Ground improves information security.
Access end is random raw first according to preset rivest, shamir, adelman before encrypting to the first information
At the second key pair for being encrypted and decrypted, i.e. the second public key and the second private key, wherein second public key for pair
Information is encrypted, and second private key is for being decrypted information, the information encrypted by second public key, it is necessary to
It is decrypted by second private key.
The second public key that access end generates it at random is together with needing to be sent to described in the first information use of accessed end
First public key is encrypted, and is formed the first ciphering two-dimension code and is sent jointly to accessed end, and second private key then by
Access end saves privately not to be disclosed outward.
Step 3: accessed end is after receiving the first ciphering two-dimension code, using first private key to described first
Ciphering two-dimension code is decrypted, and obtains the first information and the second public key, then using second public key to needing to feed back
It is encrypted to the second information of access end, forms the second ciphering two-dimension code, and the second ciphering two-dimension code is sent to visit
Ask end；
In the step 3, by the information of second public key encryption, it is necessary to be decrypted, and obtained by second private key
Second public key, and need first private key and the first information is decrypted, therefore in accessed end to access
When end is fed back, even if the second ciphering two-dimension code is stolen, due to lacking second public key, second encryption two
The second information in dimension code will not leak, and greatly improve information security.
Step 4: access end is added after receiving the second ciphering two-dimension code, using second private key to described second
Close two dimensional code is decrypted, and obtains second information.
In the step 4, even if someone emits and recognizes accessed end and feed back to access end, lacks due to emitting the person of recognizing and added
Close second public key, if therefore access end the second ciphering two-dimension code for receiving can not be carried out using second key
If decryption, then can be determined that the second ciphering two-dimension code that can not be decrypted be it is false, someone recognizes accessed end to access emitting
It is fed back at end.
