Description
Technical Field
The embodiment of the specification relates to the technical field of networks, in particular to a method and device for preventing transaction cross-chain replay and electronic equipment.
Background
In a federated chain, there are multiple privately deployed federated chains. For example, participant M may be in two different federated chains chain-A and chain-B at the same time, where both blockchain systems M have the authority to transmit transactions as well. If party M uses the same private key in both chains, then the transaction it sent on chain-a may be taken over by a malicious attacker for replay on chain-B, so that it cannot be determined for chain-B whether the transaction was actively sent by M or replayed across chains by a malicious attacker.
One existing solution is to add fields in the transaction, such as a field to add a chain ID (chain_id), which is generated randomly when the chain is initialized and then cured into the creation block and not allowed to be modified when the privately deployed. By adding the chain_id field in the transaction, a user designates the chain_id when sending the transaction, and the node prevents the transaction from being replayed across chains by judging whether the chain_id is matched when receiving the transaction. This approach has two drawbacks, in that if the area of the chain_id is not large enough, collision is easy to occur, and at the same time, the increase of the chain_id in the transaction makes the transaction volume bigger, and increases the burden of storage and communication.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present specification more apparent, the technical solutions of the embodiments of the present specification will be clearly and completely described below in connection with the specific embodiments of the present specification and the corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the embodiments herein, are intended to be within the scope of the embodiments herein.
The following describes in detail the technical solutions provided by the embodiments of the present specification with reference to the accompanying drawings.
Example 1
Referring to fig. 1, a schematic diagram of steps of a method for preventing cross-chain replay of a transaction according to an embodiment of the present disclosure is provided, and the method is applied to a blockchain system, and includes:
step 101: calculating a first transaction initial abstract according to the transaction content to be signed;
step 102: calculating a transaction digest according to the first transaction initial digest and the generation block digest;
step 103: signing the transaction abstract and sending a transaction;
step 104: calculating a second transaction initial abstract according to the transaction content in the received signature transaction;
step 105: calculating and verifying a transaction abstract according to the second transaction initial abstract and the generation block abstract;
step 106: and verifying the validity of the transaction according to the verification transaction digest and the transaction signature.
It should be noted that the generated block digest may include one or more of a timestamp, an initial consensus list, a blockchain identification, and an initial configuration parameter of the generated block. The uniqueness of the starting quick abstract is guaranteed, and the repeated probability of the starting quick abstract information is almost zero in the normal block chain operation process.
The method can further comprise setting an RPC interface for the blockchain system, and calling the RPC interface to acquire the created block abstract. Therefore, before sending the transaction, the user can acquire the digest of the creation block of the chain. When calculating the transaction abstract, the first transaction initial abstract is calculated according to the transaction content to be signed, then the first transaction initial abstract is added with the created block abstract to calculate the final transaction abstract, and then the transaction signature and the transmission are carried out.
The node needs a new verification signature rule in all protocols needing to verify the validity of the transaction: after receiving the transaction sent by the transactor, the node calculates a second transaction original abstract according to the transaction content, and calculates a verification transaction abstract together with the creation block abstract, and verifies the validity of the transaction according to the verification transaction abstract and the transaction signature.
Further, when the transaction is verified to be legal according to the verification transaction digest and the transaction signature, the transaction enters a transaction pool;
when a transaction is validated as illegal based on the validation transaction digest and the transaction signature, the transaction may be counterfeit or cross-chain replay from other chains, the transaction being terminated.
Meanwhile, the same transaction verification rule is required to be followed in the block verification of the consensus protocol, and if the transaction verification rule is not met, the block can be considered to be illegal, and counterfeit transaction or transaction replayed by cross-chain is included. This transaction verification rule also needs to be followed when a node receives a transaction forwarded by another node.
According to the technical scheme of the specification, in the process of constructing the transaction by the user, the transaction content and the generation block abstract are required to be involved in calculating the transaction abstract, and the user signs according to the obtained transaction abstract. When the node performs signature verification, the node also needs to verify the abstract containing the creation block, so that the problem of cross-chain replay of the transaction is economically and conveniently solved. And because additional fields such as a chain ID and the like are not required to be included in the transaction, additional storage and communication space is not required to be wasted.

transaction summary module 202: calculating a transaction digest according to the first transaction initial digest and the generation block digest;
signature module 203: for signing the transaction digest and transmitting a transaction;
the second transaction initial summary module 204: calculating a second transaction initial abstract according to the transaction content in the received signature transaction;
the verify transaction summary module 205: calculating and verifying a transaction abstract according to the second transaction initial abstract and the generation block abstract;
the verification module 206: and verifying the validity of the transaction according to the verification transaction digest and the transaction signature.
Optionally, when the verification module verifies that the transaction is legal, the transaction enters a transaction pool; the verification module verifies that the transaction is illegal and the transaction is terminated.
Optionally, the device further includes an RPC interface, and the created block digest is obtained by calling the RPC interface.
Optionally, the created block digest includes one or more of a timestamp, an initial consensus list, a blockchain identification, and an initial configuration parameter of the created block.
According to the technical scheme of the specification, in the process of constructing the transaction by the user, the transaction content and the generation block abstract are required to be involved in calculating the transaction abstract, and the user signs according to the obtained transaction abstract. When the node performs signature verification, the node also needs to verify the abstract containing the creation block, so that the problem of cross-chain replay of the transaction is economically and conveniently solved. And because additional fields such as a chain ID and the like are not required to be included in the transaction, additional storage and communication space is not required to be wasted.
It should be understood that the device described in the second embodiment may execute all the technical schemes related to the method for preventing transaction cross-link replay in the form of a functional module, and achieve corresponding technical effects, which are not described herein.
