Detailed Description
The embodiment of the application provides an account protecting and transaction verifying method and device based on a block chain.
In order to make the technical solution in the present application better understood by those skilled in the art, the present application will be combined with the following embodiments
The technical solutions in the embodiments of the present application are clearly and completely described in the drawings of the embodiments, and obviously, the described implementations
The examples are only a few examples of the present application and not all examples. Based on the embodiments in this application, it is common in the art
All other embodiments, which can be obtained by a person skilled in the art without making any inventive step, shall be covered by the present application
The range of (1).
As mentioned above, after the private key is stolen, the user cannot migrate the assets and data on the account to a new account, and there is no other beneficial measure to prevent the operation of the private key, which often results in data being tampered, assets being stolen, and the user being counterfeited. Therefore, the technical scheme of the application solves the safety problem of the block chain account, supports the verification of the real authorization and the management of the trust equipment, and can log off the equipment and replace the block chain account after the private key operation equipment is lost.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for protecting an account based on a blockchain according to an embodiment of the present application, including the following steps:
s101, a block chain account is created.
A private key is created and an account is generated as a blockchain account that a user uses to initiate a transaction. And establishing an account system on the blockchain by taking the blockchain account as a unit, wherein the account system stores common information such as assets, states and the like and also stores bound security accounts and equipment accounts. When the first transaction of the blockchain account is linked, the blockchain account on the blockchain is not bound with the security account and the equipment account. When the block chain account is not bound with the security account and the equipment account, the block chain account only needs a signature of the block chain account when initiating a transaction; otherwise the signature of the secure account or any device account is also required.
And S102, binding the safe account to the block chain account.
A user creates a security account by inputting information; then, initiating a transaction of binding the secure account by using the blockchain account, wherein the transaction only comprises the signature of the blockchain account; and the blockchain node receives the transaction, updates the configuration of the blockchain account on the blockchain when the transaction is linked, and binds a safety account for the blockchain account.
Secure accounts are used primarily to sign special transactions. The special transaction includes a change operation of the blockchain account, a binding and change operation of the secure account, and an adding and deleting operation of the device account.
The secure user may also be used for signatures for other transactions.
And S103, adding a bound device account by using the block chain account and the security account.
The user may only add the bound device account after the blockchain account has bound the secure account.
Dynamically creating an equipment account according to equipment information of a user computing device; initiating a transaction of adding a binding device account by the blockchain account, wherein the transaction comprises a signature of the blockchain account and a signature of the security account; and the blockchain node receives the transaction, modifies the configuration of the blockchain account on the blockchain during the transaction uplink and adds a binding equipment account for the blockchain account.
The device account is associated with the user equipment, and when the configuration information of one user equipment is not changed, the device account generated by the system for the same blockchain account is not changed. The device account is calculated according to the device information of the user computing device, so that no operation is required by the user, and therefore the block chain account and the device account signature can be directly used on the device for general transactions.
Thus, when a blockchain account is bound to a secure account or a device account, the blockchain requires that the blockchain account transaction contain not only the signature of the blockchain account but also the signature of the secure account or any device account. Even if the private key of a blockchain account is stolen, the blockchain can prevent the account from initiating the transaction chain with unqualified signature.
Fig. 2 is a flowchart of binding a secure account provided in an embodiment of the present application.
S201, a user inputs information.
The user inputs information, the complexity of the information is not required, and the user can input any information.
The information input mode of the user can be a keyboard input mode, a two-dimensional code scanning mode, a bar code scanning mode, a gesture input mode and the like, and the flexible input mode can help the user to use the safe account better. The bar code scanning and the gesture input have less input information, the two-dimensional code scanning operation is simple, rich information can be input, and the keyboard input and the gesture input are suitable for inputting short messages.
And S202, performing deformation processing on the information by using the block chain account to obtain deformation information.
Using a private key of the block chain account as a key of the HAMC function and carrying out HMAC calculation on the information, and if the length of a result obtained by the HMAC calculation meets the requirement of creating the private key, using the result as deformation information; otherwise, the result of the HMAC calculation, the information and the hash result of the information are spliced together to be used as the deformed information, if the length of the deformed information is not enough, the hash value of the deformed information is continuously inserted into the tail part of the deformed information until the length of the deformed information meets the requirement of creating the private key, and the deformed information obtained in the way is used as the seed of creating the private key.
Preferably, a HMAC function with a large number of bits is recommended, so that the obtained transformation information can be directly used as a seed for creating the private key.
Therefore, the same information is used by the same blockchain account to obtain the same deformation information, different blockchain accounts can also obtain different deformation information by using the same information, and therefore security accounts created by inputting the same information when different blockchain accounts are used are different.
And S203, generating a security account by using the deformation information.
And using the deformation information as a seed to create a private key, creating an account address for the private key, wherein the private key is used as a private key of the secure account, and the account address is used as an address of the secure account.
And S204, initiating a transaction of binding the secure account by using the blockchain account.
Creating a transaction bound to the secure account using the blockchain account, the transaction including an address of the blockchain account, an address of the secure account, a signature of the blockchain account. Preferably, the signature of the secure account is included in the transaction, so that whether the user mistacks the secure account address can be confirmed through the signature of the secure account while ensuring that the user has a private key corresponding to the secure account address.
Submitting the transaction to the blockchain node, and waiting for the blockchain to chain up the transaction.
S205, transaction cochain, binding the secure account.
The block chain export node verifies the transaction, and at the moment, the block chain account does not bind the security account and the equipment account on the block chain, so the export node only requires that the transaction has the signature of the block chain account. If the transaction is valid, the account system of the blockchain account binds the safe account in the transaction when the transaction is linked. At this time, the blockchain account successfully binds to a secure account, the blockchain account can add an equipment account, and the blockchain account must have a signature of the secure account when initiating a transaction.

S302, extracting the equipment information to obtain key equipment information.
And extracting the equipment information, and removing indiscriminate and unstable information to obtain key equipment information.
And S303, processing the key equipment information by using the block chain account to create an equipment account.
Using a private key of the block chain account as a key of the HAMC function and carrying out HMAC calculation on key equipment information, and if the length of a result obtained by the HMAC calculation meets the requirement of creating the private key, using the result as deformed key equipment information; otherwise, the result of the HMAC calculation, the key equipment information and the hash result of the key equipment information are spliced together to be used as the deformed key equipment information, if the length of the deformed key equipment information is not enough, the hash value of the deformed key equipment information is continuously inserted into the tail part of the deformed key equipment information until the length of the deformed key equipment information meets the requirement of creating the private key, and the deformed key equipment information obtained in the way is used as the seed of creating the private key.
Thus, the same blockchain account obtains the same deformed key device information on the same device, and different blockchain accounts obtain different deformed key device information on the same device, so that device accounts created by one user when using a plurality of blockchain accounts on the same device are different.
And using the deformed key device information as a seed and creating a private key, and simultaneously creating an account address for the private key, wherein the private key is used as the private key of the device account, and the account address is used as the address of the device account.

And creating a transaction for adding the bound device account by using the blockchain account, wherein the transaction comprises the address of the blockchain account, the address of the security account, the address of the device account, the signature of the blockchain account and the signature of the security account. Preferably, the signature of the device account is included in the transaction, so that it can be confirmed whether the device account address is correct by the signature of the device account.
Submitting the transaction to the blockchain node, and waiting for the blockchain to chain up the transaction.
S305, transacting uplink and binding the equipment account.
And the block chain exit node verifies the transaction, at the moment, the secure account is bound on the block chain account chain, and the block exit node requires the transaction to have the signature of the block chain account and the signature of the secure account bound by the block chain account. If the transaction is valid, the account system of the blockchain account adds the device account address in the transaction to the device account list of the blockchain account when the transaction is uplink. At this time, the blockchain account successfully adds the device account, and the signature of the device account can be used when the blockchain account initiates a normal transaction.

Creating a new private key and generating an account as a blockchain account, or generating a blockchain account by importing a private key that has already been generated but the corresponding account has not yet been linked.
S402, preparing a new security account.
The user creates a secure account with the new blockchain account by entering information.
The embodiment of the present application and the schematic diagram of the bound secure account shown in fig. 2 are embodiments based on the same inventive concept, and for explanation of related concepts, reference may be made to the explanation of the schematic diagram of the bound secure account shown in fig. 2.
S403, creating a transaction for replacing the blockchain account.
A transaction is created from the old blockchain account that changes accounts, the transaction including a signature of the old blockchain account, a signature of the old secure account, an address of the new blockchain account, and an address of the new secure account. Preferably, the transaction includes a new blockchain account signature, a new secure account signature.
S404, initiating a transaction for replacing the blockchain account.
The transaction is submitted to the blockchain node, and uplink is requested.
S405, performing transaction uplink, creating a new block chain account, binding a new security account, and processing an old account.
The blockchain node verifies the transaction, confirms whether the signature of the old blockchain account is accurate, confirms whether the signature of the old safety account is accurate, confirms whether the address of the new blockchain account and the address of the safety account are accurate, preferably, verifies whether the signature of the new blockchain account and the signature of the new safety account are accurate, and if the requirements are met, the transaction can be linked. The job of the transaction uplink includes: creating a new blockchain account, binding a new secure account address in the transaction to the new blockchain account, filtering invalid information from state data of an old blockchain account, and transferring the invalid information to the new blockchain account, wherein the invalid information comprises a secure account and an equipment account list of the old blockchain account; the old blockchain account is marked as migrated to the new blockchain account, and optionally, the old blockchain account may be deleted.
The private key is dynamically generated by the security account through the input information, the private key of the security account is not stored, and the private key of the security account is not spread, so that the private key corresponding to the security account is not lost and is not stolen. Therefore, when the user encounters or subjectively thinks that the blockchain account is lost or stolen, the blockchain account can replace the old blockchain account with the new blockchain account by using the mode, and simultaneously replace the old security account with the matched new security account.
Fig. 8 is a flowchart of a method for validating a transaction based on a blockchain according to an embodiment of the present application.
The transaction types are divided into special transactions and common transactions, and more specifically, the special transactions include replacement operations of the blockchain account, binding and replacement operations of the secure account, and addition, deletion and modification operations of the device account. The number of signatures of the signature part of the transaction is undetermined and needs to be judged according to the transaction type and whether the transaction creation account is bound with a security account.
The block chain is required to inquire whether a transaction creator is bound with one or more secure accounts or multiple device accounts.
Where a special transaction requires a signature of a secure account. Preferably, the special transaction may also include a signature for the blockchain account, where the signature portion of the transaction has 2 signatures.
At step 504, it is determined whether the transaction contains a signature for a secure account.
Preferably, if the signature part of the transaction contains 2 signatures, it is further determined that another signature belongs to the signatures of the blockchain accounts, and if not, the transaction is rejected, and the process ends.
It is necessary to determine whether the signature includes a signature of any one of the secure account and all device accounts. Preferably, the transaction may further include signatures of the blockchain accounts, where the signature part of the transaction has 2 signatures, and it is further necessary to determine that another signature belongs to the signatures of the blockchain accounts, and if not, the transaction is rejected, and the process ends.
At step 506, it is determined whether the transaction includes a signature for the blockchain account.
The signature part of the transaction can only have 1 signature, namely the signature of the blockchain account.
Before the created account of the transaction is not bound with the security account, only the special transaction of the bound security account is supported, and the uplink is refused by other special transactions of specific types.
In step 509, the signature check passes and the other operations continue.
The method for verifying the transaction provided by the invention mainly relates to signature verification, and does not relate to parts except for signature verification, so other operations in the verification transaction are not described. Signature verification is only part of the verification transaction, but other operations must actually continue in the verification transaction.
