Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In order to solve the technical problem that the network address is configured by a DNS server with strong centralization, which causes easy attack in the background art, the invention provides a block chain domain name resolution method based on a user terminal operating system, which obtains the naming in a decentralized mode, improves the security of domain name sending of an application program, and avoids behaviors such as phishing attack of hackers.
Specifically, in order to solve the above technical problem, the present invention provides a domain name generation blockchain network, as shown in fig. 1, in the blockchain network, an internet service provider ISP node sends an identity-based encryption (IBE) based identity-private key request message to a blockchain domain name system server to which the internet service provider ISP node belongs, where the identity-private key request message includes: the method comprises the steps that a target domain name and a corresponding IP address are applied, a block chain domain name system server receives an identity private key request message and analyzes the identity private key request message to obtain the target domain name, a locally stored main key and a locally stored public parameter are inquired, the main key, the public parameter and the target domain name are calculated according to a preset algorithm to generate an identity private key of an ISP node, the identity private key is uniquely corresponding to the ISP node, the target domain name is an identity public key of the ISP node, the node public key of the ISP node in a block chain is used for encrypting the identity private key of the ISP node to generate an encrypted private key identity of the ISP node, and the encrypted identity private key is sent to the ISP node corresponding to the IP address corresponding to the target domain name.
Further, after receiving the encrypted identity private key sent by the block chain domain name system server, the ISP node decrypts the encrypted identity private key by using its own node private key in the block chain to obtain the identity private key of the ISP node, and sends a domain name registration broadcast message to the block chain network after performing identity private key signature on the target domain name, the corresponding IP address, and the server identifier of the block chain domain name system server by using the identity private key. And the accounting node receives the domain name registration broadcast message, analyzes and acquires a target domain name, a corresponding IP address and a server identifier, verifies the identity private key signature of the ISP node by using the target domain name, writes the corresponding relation between the target domain name and the corresponding IP address as well as the server identifier of the block chain domain name system server into a newly generated block if the verification is passed, and records the block chain account book.
Therefore, the network address generation method of the embodiment of the invention is generated based on the block chain decentralized thought of the block chain domain name system, thereby avoiding phishing attack and the like on one hand, and avoiding illegal nodes from disturbing legal generation of network addresses on the other hand based on a common identification mechanism.
However, when a client (such as an application APP) accesses a blockchain network, P2P is generally used to broadcast mutual addressing, and in order to access a P2P neighbor node, a seed node (which may also be referred to as an originating node) address in a blockchain needs to be prefabricated at the client first, and the neighbor node is obtained through the seed node. However, in practical applications, for example, when the operating system is installed, the seed node of the domain name blockchain may not be obtained, or the IP address of the seed node may change, and if the seed node is accessed by using the domain name, the blockchain network corresponding to the domain name is not accessed yet, and domain name access cannot be performed.
Therefore, in order to solve the problem that the domain name cannot be accessed when the domain name resolution module of the blockchain is built in the kernel layer of the operating system of the user terminal, the present invention further provides an information processing method based on the adjacent node of the blockchain network, in order to describe the method more clearly, first, the description is focused on the side of the information processing system based on the adjacent node of the blockchain network, fig. 2 is a schematic structural diagram of the information processing system based on the adjacent node of the blockchain network according to an embodiment of the present invention, as shown in fig. 2, the system includes the user terminal 100 and the online adjacent terminal 200, wherein the user terminal 100 and the online adjacent terminal 200 may be adjacent to each other, and in the actual execution process, after the user terminal is started, the relevant block information may be extracted from other online adjacent terminals, however, in the embodiment of the present invention, in order to avoid the situation that the obtained block information is falsified due to the fact that other adjacent blocks possibly have malicious terminals, and therefore domain name resolution is wrong, and to avoid the situation, the accuracy of the obtained block information is guaranteed.
Specifically, as shown in fig. 3, when the user terminal obtains an access request including a target domain name sent by a target application program, the user terminal queries locally stored block information according to the target domain name, and if a communication IP address corresponding to the target domain name is not obtained, queries locally currently stored node list information of an online adjacent terminal, where the node list information includes: and sending a block query request containing a target domain name signed by a private key of the user terminal to the online adjacent terminal according to the IP address of the online adjacent terminal and the block identifier set in the block chain account book which is currently and correspondingly stored by each online adjacent terminal (step 31).
Furthermore, the online adjacent terminal verifies the private key signature of the block query request by using the public key of the user terminal, if the verification is passed, the block query request is sent by the user terminal, and the stored domain name identifier library is updated in real time according to the target domain name query local terminal, wherein the domain name identifier library records the block identifier to which each domain name IP address corresponding relation in the local block information belongs, and if the target block identifier recorded corresponding to the target domain name can be obtained from the domain name identifier library, the target block identifier is fed back to the user terminal (step 32), that is, in this embodiment, the feedback of the target block identifier is performed based on the adjacent terminal instead of the block content, so that the false block content and the like after malicious adjacent terminal sends a falsification is avoided.
Further, the user terminal verifies the validity of a target block corresponding to the target block identifier according to a preset policy, if the target block is verified to be valid, the user terminal queries a block identifier set in a block chain book currently and correspondingly stored in each online adjacent terminal in the node list information, acquires any online target adjacent terminal containing the target block identifier, sends an address query request containing a target domain name to the online target adjacent terminal according to a target IP address corresponding to the online target adjacent terminal stored in the node list information, receives a communication IP address corresponding to the target domain name and fed back to the target application program, so that the target application program sends an access request according to the communication IP address, namely, the access to the block chain network is realized (step 33).
Therefore, in the embodiment of the invention, the access to the block chain network is realized when the user terminal is started, and when the user terminal initiates a domain name query request, in order to avoid phishing attacks, the adjacent terminal feeds back not the domain name query result but the block identifier corresponding to the domain name query result, and the user terminal finds the corresponding block according to the block identification and searches the corresponding domain name record for resolution, thereby ensuring the accuracy of domain name resolution.
Next, an information processing method based on a neighboring node of a blockchain network according to an embodiment of the present invention is described in detail, and fig. 4 is a flowchart of the information processing method based on a neighboring node of a blockchain network according to an embodiment of the present invention, as shown in fig. 4, the method includes:
The target application should be an application that initiates a domain name access request, such as a surf application to be installed.
It should be understood that, in the embodiment of the present invention, in order to improve the efficiency and the security of domain name resolution, a part of the block information is cached locally in the user terminal, so that the relevant block information can be read without being requested in other terminals, and therefore, in this embodiment, the locally stored block information is queried in advance according to the access request with the target domain name, wherein, as described above, the block information records domain name information with an IP address and corresponding to the IP address, and the like, and if the communication IP address corresponding to the target domain name is not obtained, the node list information of the locally currently stored online neighboring terminals is queried, and the node list information includes the IP address of each online neighboring terminal and the block identifier set in the block chain book currently stored corresponding to each online neighboring terminal, wherein it should be understood that, the block identifier set includes unique identifiers of all blocks stored in the corresponding terminal.
Furthermore, a block query request containing a target domain name signed by a private key of the user terminal is sent to the online adjacent terminal according to the IP address of the online adjacent terminal, in the example, the identity of the user terminal is authenticated based on a public key certificate mechanism, and since the private key of the user terminal is only held by the user terminal, other illegal terminals are prevented from being disguised as the user terminal to send the query request.
102, verifying the private key signature of the block query request by using the public key of the user terminal at the online adjacent terminal, if the verification is passed, updating a stored domain name identification library in real time according to the target domain name query local terminal, wherein the domain name identification library records the block identification to which each domain name IP address corresponding relation in the local block information belongs, and if the target block identification recorded corresponding to the target domain name can be obtained from the domain name identification library, feeding the target block identification back to the user terminal.
Specifically, the online adjacent terminal verifies the private key signature of the block query request by using the public key of the user terminal, if the public key of the user terminal is matched with the private key, the query request is sent by the user terminal, so that the verification is passed, the adjacent terminal queries a name identifier library updated in real time by the local terminal according to a target domain name, wherein the domain name identifier library records a block identifier to which each domain name IP address in the local block information belongs, and if the target block identifier recorded corresponding to the target domain name can be obtained from the domain name identifier library, the target block identifier is fed back to the user terminal, so that the user terminal can know which block stores the corresponding domain name information.
In one embodiment of the invention, if the online adjacent terminal cannot obtain the record corresponding to the target domain name from the domain name identification library, inquiring the locally stored node list information of the online adjacent terminal, sending a block inquiry request containing the target domain name to other terminals adjacent to the terminal, that is, the number of neighboring terminals that can provide services is increased, the neighboring terminals of the neighboring terminals join the terminal to be inquired, and further, the online adjacent terminal receives the target block identification recorded corresponding to the target domain name and fed back by other terminals, and feeds back the target block identification to the user terminal, in the actual execution process, the block query request containing the target domain name may be sequentially sent to other terminals adjacent to the online adjacent terminal itself until the corresponding target block identifier is obtained, or the block query request containing the target domain name may be simultaneously sent to other terminals adjacent to the online adjacent terminal itself.
103, the user terminal verifies the validity of a target block corresponding to the target block identifier according to a preset strategy, if the target block is verified to be valid, the user terminal inquires a block identifier set in a block chain book which is currently and correspondingly stored in each online adjacent terminal in the node list information, acquires any online target adjacent terminal containing the target block identifier, sends an address inquiry request containing a target domain name to the online target adjacent terminal according to a target IP address which is stored in the node list information and corresponds to the online target adjacent terminal, receives a communication IP address which is fed back by the online target adjacent terminal and corresponds to the target domain name, and feeds back the communication IP address to the target application program, so that the target application program sends an access request according to the communication IP address.
In order to ensure that the domain name identification library of the adjacent terminal can store the latest block information in real time, the online adjacent terminal always inquires the domain name information contained in a new block in a locally stored block chain account book, and updates the block identification to which the new domain name IP address corresponding relation belongs in the domain name identification library.
Certainly, in order to ensure the accuracy of domain name resolution, the user terminal needs to verify the validity of the target block, and verifies the validity of the target block corresponding to the target block identifier according to a preset policy, if the target block is verified to be valid, it is indicated that the target block identifier indeed corresponds to the target block, and then a block identifier set in a block chain account book currently and correspondingly stored by each online adjacent terminal in the node list information is queried.
Further, any online target adjacent terminal containing the target block identifier is obtained, an address query request containing a target domain name is sent to the online target adjacent terminal according to a target IP address corresponding to the online target adjacent terminal and stored in the node list information, a communication IP address corresponding to the target domain name and fed back by the online target adjacent terminal is received, and the communication IP address is fed back to the target application program, so that the target application program sends an access request according to the communication IP address. Therefore, the validity of the target block is verified, and the address query request is randomly sent from any adjacent terminal, so that the accuracy of domain name resolution is ensured, and the stability of a block chain network is ensured.
It should be noted that, in different application scenarios, the way in which the user terminal verifies the validity of the target block corresponding to the target block identifier according to the preset policy is different, which is exemplified as follows:
the first example:
in this example, the user terminal sends a block query request containing a target domain name signed by a private key of the user terminal to any online adjacent terminal according to an IP address of any online adjacent terminal, so that the user terminal sends a hash query request carrying a target block identifier to any online adjacent terminal, receives a target block hash value corresponding to the target block identifier and fed back by any online adjacent terminal, where the hash value uniquely corresponds to a block, queries locally pre-stored hash records of all blocks according to the target block identifier, obtains a reference hash value corresponding to the target block identifier, compares the reference hash value with the target block hash value, and if the two hash values are the same, indicates that the target block is real, and determines that the target block corresponding to the target block identifier is valid.
The second example is:
in this example, the user terminal simultaneously sends a block query request containing a target domain name signed by a private key of the user terminal to a plurality of online neighboring terminals according to IP addresses of the plurality of online neighboring terminals. And then, the user terminal receives the target block identifications respectively fed back by the plurality of online adjacent terminals, compares all the target block identifications, judges whether the number of the same target block identifications is greater than a preset threshold value, and if the number of the same target block identifications is greater than the threshold value, the block identifications corresponding to the target block, which are recorded by most adjacent terminals with the expression, are consistent with the target block identifications, so that the target block corresponding to the same target block identification is determined to be valid. The threshold corresponding to the number is determined according to the number of the online adjacent terminals, so as to ensure that the accuracy of the verification result is determined by most adjacent terminals.
Therefore, as shown in fig. 5, in the information processing method based on the adjacent nodes of the block chain network according to the embodiment of the present invention, on one hand, when the block information corresponding to the access request currently including the target domain name can be locally checked, the block information is directly fed back to the user terminal, so that the efficiency and reliability of domain name resolution are improved, when the block information corresponding to the access request currently including the target domain name cannot be locally checked, the node list information of the online adjacent terminal currently stored in the local is queried, the block identifier corresponding to the target domain name is obtained from the adjacent terminal, instead of directly obtaining the block information, so that domain name resolution distortion caused when the adjacent terminal is a malicious node is avoided, and further, when the block corresponding to the block identifier is verified to be reliable, domain name resolution is performed according to the valid block.
To sum up, in the information processing method based on the adjacent nodes of the blockchain network according to the embodiment of the present invention, when the user terminal obtains the access request including the target domain name sent by the target application program, the user terminal queries locally stored blockchain information according to the target domain name, and if a communication IP address corresponding to the target domain name is not obtained, queries locally currently stored node list information of the online adjacent terminal, where the node list information includes: the IP address of each online adjacent terminal and the block identifier set in the block chain account book which is stored correspondingly at present in each online adjacent terminal, and a block query request which is signed by a private key of a user terminal and contains a target domain name is sent to the online adjacent terminal according to the IP address of the online adjacent terminal, the online adjacent terminal verifies the private key signature of the block query request by using a public key of the user terminal, if the verification is passed, the local terminal is queried according to the target domain name to update a stored domain name identifier library in real time, wherein the domain name identifier library records the block identifier of each domain name IP address corresponding relation in the local block information, if the target block identifier which is recorded corresponding to the target domain name can be obtained from the domain name identifier library, the target block identifier is fed back to the user terminal, and then the user terminal verifies the validity of the target block corresponding to the target block identifier according to a preset strategy, if the target block is verified to be valid, inquiring a block identifier set in a block chain account book which is currently and correspondingly stored by each online adjacent terminal in the node list information, acquiring any online target adjacent terminal containing the target block identifier, sending an address inquiry request containing a target domain name to the online target adjacent terminal according to a target IP address which is stored in the node list information and corresponds to the online target adjacent terminal, receiving a communication IP address which is fed back by the online target adjacent terminal and corresponds to the target domain name, and feeding back the communication IP address to the target application program, so that the target application program sends an access request according to the communication IP address. Therefore, the domain name is obtained in a decentralized block chain mode, when an application program accesses the domain name and accesses the block chain network based on the information in the block, the authenticity of the block is guaranteed, the behaviors of hackers such as phishing attack and the like are avoided, and the flexibility of the block chain network is improved.
