Description

Data processing method and device suitable for blockchain

technical field

The present invention relates to the technical field of computer security processing, and in particular, to a data processing method and device suitable for blockchain.

Background technique

In a distributed system, when a node fails, it can lead to the collapse of the entire system. Node errors can be caused by unpredictable errors in the computing infrastructure, such as hardware failures that cause computers to crash and become unresponsive, or by malicious human operations. System errors caused by malicious tampering with protocol programs, attacking the underlying technology stack of the operating system, hardware execution environment, intercepting network messages, and modifying messages are called Byzantine errors. In order to predict man-made malicious behavior, it is necessary to model and analyze the participants in the distributed system, but in practical situations, the information of the relevant participants in the distributed system is usually imperfect and private, which makes the The number of Byzantine errors is difficult to determine. Since the number of Byzantine errors in a distributed system cannot be accurately determined, it is necessary to design a consensus algorithm that can handle as many Byzantine errors as possible. The Paxos algorithm and the Raft algorithm are proposed to solve the problem of distributed system consistency, but they do not consider the existence of Byzantine errors in the system, that is, do not consider the existence of malicious nodes in the distributed system. The proposed PBFT algorithm makes the distributed system tolerate no more than 1/3 of malicious nodes. However, if the malicious nodes in the distributed system exceed 1/3 of the total nodes, malicious attackers can still damage the security of the system by tampering with code or data, causing serious damage to the system.

Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 shows a data processing method applicable to a blockchain provided by an embodiment of the present invention, including:

S11, the target node obtains the target data and the target request, executes the preset consensus protocol code, and generates a consensus message corresponding to the target request, and the consensus protocol code is placed in a trusted execution environment;

S12. Execute the preset TLS protocol code to encrypt the consensus message, obtain the encrypted consensus message, and execute the preset TCP protocol code to encapsulate the encrypted consensus message and transmit it to the check node, so that the encrypted consensus message is encapsulated by the preset TCP protocol code. The check node obtains a consensus message, sends a confirmation message according to the consensus message, the TLS protocol code is placed in a trusted execution environment, and the TCP protocol code is placed outside the trusted execution environment;

S13. After receiving the confirmation message from the check node, generate and store the target data into an encrypted file according to the target request, and execute the consensus protocol code at the same time to generate a storage request corresponding to the target data;

S14. Execute the TLS protocol code to encrypt the storage request, obtain an encrypted storage request, and execute the TCP protocol code to encapsulate the encrypted storage request, and transmit it to the check node, so that the The check node obtains the storage request, and generates an encrypted file from the target data and stores it according to the storage request.

Regarding step S11, it should be noted that, in the embodiment of the present invention, the method is used for fault tolerance against Byzantine errors in the blockchain field. Blockchain is an application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The blockchain is essentially a decentralized database that enables data sharing among processing nodes. Here, in order to clearly describe the method, in this embodiment, one of the processing nodes is used as the target node, and the other processing nodes are used as the check nodes for description.

In this embodiment of the present invention, the confidentiality and integrity of key codes and data can be guaranteed due to the Trusted Execution Environment (TEE). Therefore, in the embodiment of the present invention, the consensus protocol code is placed in a trusted execution environment. The consensus protocol code includes Raft protocol, PBFT protocol or Pow protocol, but is not limited to this. The consensus protocol code is placed in a trusted execution environment, and attackers cannot obtain or tamper with the code. However, an attacker can compile the tampered code and execute it in a trusted execution environment. In order to detect this kind of tampering, it is necessary to obtain the consensus protocol code sent by the check node to determine whether the preset consensus protocol code of each node is the same, and when it is determined that the preset consensus protocol code of each node is the same, obtain the target data and target ask. In addition, it should be noted that an external verification platform can be used to judge whether the consensus protocol codes preset by each node are the same.

In the embodiment of the present invention, the target node obtains target data and target request. For example, the target data is "A", and the target request is "Please write A to the hard disk".

The target node executes the consensus protocol code to generate a consensus message corresponding to the target request. For example, the consensus message is "Please prepare to write A to the hard disk". The consensus message is used to send to other check nodes to reach a consensus with each check node.

Regarding step S12, it should be noted that, in this embodiment of the present invention, there is data transmission between the target node and the check node. During the transmission process, it is easy for an attacker to tamper with the code of the communication part and generate erroneous data. In order to make it impossible for attackers to forge the message, the message can be encrypted. Execute the preset TLS protocol code to encrypt the consensus message to obtain the encrypted consensus message. Here, the TLS protocol code is placed in a trusted execution environment. In fact, only the asymmetric and symmetric keys required for encryption can be kept in the trusted execution environment, and attackers cannot obtain them.

At the transport layer, the target node transmits the message to the check node. Execute the preset TCP protocol code to encapsulate the encrypted consensus message, obtain a TCP data packet, and transmit it to the check node, so that the check node obtains the consensus message and sends out the confirmation message according to the consensus message. Wherein, the TCP protocol code is placed outside the trusted execution environment. As a result, the attacker controls the TCP data packets in the untrusted execution environment, and cannot forge legitimate TLS data packets.

In the embodiment of the present invention, after obtaining the TCP data packet, the check node executes the TCP protocol code to decapsulate the data packet, and obtains the encrypted consensus message. Then execute the preset TLS protocol code decryption to obtain a consensus message, and issue a confirmation message according to the consensus message. For example: the confirmation message is "ready to write A to the hard disk".

Regarding step S13, it should be noted that, in this embodiment of the present invention, after each check node feeds back a confirmation message to the target node, the target node will generate and store the target data into an encrypted file according to the target request. For example, encrypt "A" into "akj23lc45" and write it to the hard disk. In addition, when an individual check node fails and fails to feed back confirmation information to the target node, as long as the number of failed nodes in the system does not exceed 1/2, the consensus protocol can ensure the security and availability of the system. In the embodiment of the present invention, since the consistency of each node needs to be achieved, after storing the target data, the target node will simultaneously execute the consensus protocol code to generate a storage request corresponding to the target data. The storage request includes target data and a storage message. For example: the storage message is "Allow A to be written to the hard disk".

With respect to step S14, it should be noted that in this embodiment of the present invention, the TLS protocol code is executed to encrypt the storage request, an encrypted storage request is obtained, and the TCP protocol code is executed to encrypt the storage request. The request is encapsulated and transmitted to the check node, so that the check node obtains a storage request, and generates an encrypted file from the target data and stores it according to the storage request. For example, encrypt "A" into "kop28qw15" and write it to the hard disk.

A data processing method suitable for blockchain provided by the embodiment of the present invention, by placing the consensus protocol code in a trusted execution environment to run, and the TLS protocol in the execution environment completes message encryption, so that attackers cannot tamper with the trusted execution environment. The program code and data in the execution environment eliminate the possibility of Byzantine errors in the distributed system, ensure the confidentiality and integrity of the data, and enable the consortium blockchain to meet enterprise-level needs in terms of security performance.
