Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a method for applying a block chain verification code according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the present invention provides a method for applying a blockchain verification code to a server, where the server is authorized to store or obtain a public key and a corresponding address of each user, and the method includes:
s11: responding to the user terminal of the first user to trigger verification of the verification code, and randomly generating a first verification code;
s13: encrypting the first verification code according to a first public key of a first user to generate first encrypted information;
s15: generating a first transaction according to a first address of a first user and first encryption information, and sending the first transaction to a node of a first block chain through a second address of a server for execution so as to record the corresponding relation of the second address, the first address and the first encryption information on the first block chain;
s17: sending a second address to a user side of the first user, so as to query the corresponding relation between the second address and the first address in the data of the first block chain to obtain first encrypted information, and decrypting the first encrypted information by using a first private key corresponding to the first public key to obtain a second verification code;
s19: and receiving a second verification code sent by the user side of the first user, and comparing whether the second verification code is the same as the first verification code to judge whether the second verification code is valid.
The method is exemplarily explained below by taking an example that a user side of a user a requests service data from a server side of the X software and verification of a verification code of the server side of the X software is triggered.
In the embodiment, the server side of the X software is configured in a single centralized server; in another embodiment, the service end of the X software may be configured in a node of the first blockchain (specifically, may be configured as a contract of the first blockchain, may also be configured as a local service of the node of the first blockchain, and the like), and may also be configured in a node of the second blockchain (also may be configured as a contract or a local service, and the like).
In this embodiment, the server of the X software requires the user to provide a public key and a corresponding address when registering an account, so that the public key and the corresponding address of each user are stored; in another embodiment, the server of the software X may be further configured to require the user to authorize the server to obtain the public key and the corresponding address of the user when performing the verification of the verification code when registering the account, which may achieve the same technical effect.
When the user side of the user A requests service data from the service side of the X software, the verification of the verification code is triggered:
in step S11, the server of the X software randomly generates a first verification code c of several digit characters in response to the trigger1；
In step S13, the server of the X software stores the public key P of the user aAFor the first verification code c1Performing encryption to generate first encrypted information m1；
In step S15, the server of the X software adds according to the address add of the user a storedAWith the first encryption information m1Generating a first transaction tx1And through the address add of the serverSSending the data to a node of a first block chain;
the nodes of the first blockchain receive tx1Then, tx1Broadcast to other nodes of the first blockchain network and transmit tx1Packing into blocks for execution, so that add is carried out after execution results pass consensusS、addAAnd m1The corresponding relation of (a) is recorded on the first block chain;
in step S17, the server of the X software will addSSending the data to a user side of a user A;
user A's client receives addSThen, the addS and add are inquired in the data of the first block chainATo obtain the first encryption information m1And by corresponding to the public key PAPrivate key p ofATo m1Decrypting to obtain a second verification code c2(ii) a Wherein, when a plurality of add are inquired in the data of the first block chainSAnd addATaking the latest item when corresponding to the relation;
in step S19, the server side of the X software receivesThe second verification code c sent by the user end of the user A2Comparing the second verification code c2And a first verification code c1Whether or not they are the same:
if not, the second verification code c2Invalid;
if yes, the second verification code c2And effectively, sending the requested service data to the user terminal of the user A.
In addition, when the server of the X software is configured as a local service of a node of the first blockchain or the second blockchain, the principle of executing the method is basically the same as the example, and is not described again; when the server side of the software X is configured as a contract of the first blockchain or the second blockchain, the principle of performing the method is different from the example in that the second address needs to be sent to the user side through the local service configured by the node in step S17, and the user side packages the second verification code into the second transaction tx in step S192Sending to blockchain nodes to trigger the above contract execution tx2。
In the embodiment, the verification code encrypted according to the user public key and the corresponding relation between the user address and the server address are recorded on the blockchain, so that the user side can inquire the encrypted verification code on the blockchain, decrypt the encrypted verification code through the user private key and send the decrypted verification code to the server for verification, and therefore, the verification code scheme which does not need to bind a mobile phone number or hardware equipment and is suitable for a decentralized system is realized.
Preferably, the first verification code is configured with a validity period of a fixed duration or a fixed number of block heights, and the validity period of the validity period is the time point or the block height of the first transaction recorded on the first blockchain.
For example, the first verification code c1Is configured to be 300 seconds or 50 block heights when tx1When the packed blocks are recorded on the first block chain by consensus, the first service end acquires the time point t1Or the block height h of the block1The first verification code c1Taking effect;
when the first service end receives the second verification code c2Does not exceed 300 seconds (t1+300s) or 50 block heights (h)1+50), the second verification code c2Not failed, compare c2And c1Whether they are the same;
when the first service end receives the second verification code c2Over 300 seconds (t)1+300s) or 50 block heights (h)1+50), the second verification code c2And if the verification fails, the verification fails.
The above 300 seconds and 50 block heights are only examples, and the validity period can be configured to any different time length or number of block heights according to actual requirements.
The embodiment further ensures the security of the verification code by configuring the verification code with an expiration date and verifying whether the verification code is expired.
Further preferably, the first transaction, and the correspondence between the second address, the first address, and the first encryption information further include an authentication code identifier. The querying at the user side further comprises querying according to the authentication code identifier.
Specifically, when the same user triggers the same server to perform multiple times of verification of the verification codes within a short time, the encrypted information of each verification code may not be recorded on the block chain in time sequence due to various reasons, or two or more items of encrypted information are packed in the same block and recorded on the block chain at the same time, so that the user cannot accurately distinguish each verification code, and the problem can be effectively solved by configuring the verification code identifier.
For example, tx1Further comprising an authentication code identifier n1，tx1After the packed blocks pass consensus, addS、addA、n1And m1The corresponding relation of (a) is recorded on the first block chain; client add through queryS、addA、n1Can accurately find m1And the encryption information recorded on the block chain in sequence or at the same time in a short time cannot be distinguished.
The above embodiment further records the verification code identifier on the block chain, so that the user side can accurately find the encrypted information of the verification code when needing to obtain different verification codes of a plurality of same service sides in a short time.
