Description
Technical Field
The present invention relates to the field of data processing, transmission and encryption technologies, and in particular, to a blockchain system, a data processing method, a device, and a storage medium thereof.
Background
With the popularization of 5G technology, the network has realized remote area coverage and is accelerated again; but the requirements for speed and safety in the production life of people still cannot be met in practice. The quantum computation speed is high, the signal safety is high, and the popularization process is still blocked due to high requirements on the working environment. Existing cloud service providers may offer a basic cryptographic key scheme to protect cloud-based application development and services, or they may decide to give these protective measures to the cloud user. When a cloud service provider provides a scheme for supporting robust key management to develop, more work needs to be done to overcome the obstacle of adopting a key management technology; the protection key store must be protected just as well for other sensitive data. Protection is necessary in storage, transmission and backup. Improper key storage may compromise all encrypted data; access to the key store, which must be restricted to only certain entities that need a separate key, and associated policies to manage the key store, use role separation to facilitate access control: the entity using a given key cannot be the entity storing the key; finally, it is key backup and recovery, and losing keys undoubtedly means that the data protected by these keys is lost. Although this is an effective process of destroying data, accidental loss of keys protecting mission-critical data destroys a business, and so must implement secure backup and recovery solutions, which are security problems and solutions in cloud environments, there is no "fully secure" solution in the market today.
When data encryption, private key encryption and other conditions are involved in the block chain technology, the block chain technology is realized by adopting a technical means of combining symmetric encryption and asymmetric encryption, particularly, a Hash algorithm is used for solving the problem, which is one of core technologies for ensuring that block chain data cannot be tampered, but the Hash encryption algorithm has the great problems of low encryption and decryption speed and long time; in addition, due to the different choices of the consensus algorithm, if the POW algorithm is selected, the time taken for forming a block is longer due to the high calculation force requirement and the long time taken for the consensus process, and particularly, the problem is more prominent in the application occasions where the uplink data is larger and the throughput is required; this is also one of the factors limiting the spread of the block chain technology.

Example 1
The embodiment provides the subject contents related to the hardware entity part: a blockchain system, comprising: the node is used for being connected with at least one of the common node or the common node so as to receive, send and process the block chain data; at least one common node is any one of a quantum computer system, a quantum cloud server and a quantum virtual machine; the common node is any one of a quantum computer system, a quantum cloud server, a quantum virtual machine and a computer system. As shown in fig. 2, is a quantum computing system of the type involved in quantum computing.
The node may be a common node, a consensus node, or any physical or virtual terminal to which the common node or the consensus node may be connected. Blockchain data refers to various types of data transmitted, exchanged, and stored in the blockchain, including but not limited to blockchain account addresses, transactions, blocks, smart contracts, and various types of messages; the blockchain data format is not limited and includes, but is not limited to, voice, text, picture, video, audio, and the like.
If only one quantum computer system exists, a quantum virtual machine is arranged on the quantum computer system, and a sending end and a receiving end are respectively arranged by using the quantum virtual machine for virtualization processing, so that the virtual machine can be presented in various network scenes.
As one of optional implementation manners of this embodiment, the system further includes a conversion unit, and the computer system is connected to the quantum computer system, the quantum cloud server, and the quantum virtual machine through the conversion unit;
and the conversion unit is used for quantum bits of the quantum computer system, the quantum cloud server and the quantum virtual machine and classical bit units of the computer system.
As an optional implementation manner of this embodiment, any one of the quantum computer system, the quantum cloud server, and the quantum virtual machine is respectively used as a receiving end and a transmitting end, and is used for performing quantum key distribution.
As one of the optional embodiments of this embodiment, the method further includes: if the consensus node or the common node is a computer system, the computer system is any one of a relay node, an edge computing node, a fog computing node or a cloud computing node.
As an optional implementation manner of this embodiment, if the blockchain data sent by the consensus node is encrypted data, the method further includes an encrypting unit; the encryption unit is connected with the conversion unit, and the block chain data to be encrypted is used for quantum key distribution.
As an optional implementation manner of this embodiment, if the blockchain data received by the consensus node is encrypted data, the consensus node further includes a decryption unit; the decryption unit is connected with the conversion unit and used for decrypting the block chain data to be decrypted.
As an optional implementation manner of this embodiment, the relay node is connected to a quantum computer system, a quantum cloud server, or a quantum virtual machine, and the relay node includes a satellite, a 5G base station, or a 6G base station.
The satellite, the 5G base station or the 6G base station and the like are used as relay nodes or one of the nodes of the block chain system to participate in data exchange, so that the coverage range of network signals can be enlarged, meanwhile, the response speed of the data exchange can be increased by virtue of the advantages of the block chain and quantum computation, and the advantages of data safety, stability and authenticity are achieved.
The technical scheme of the embodiment is that the Chinese patent application numbers are as follows: 202010551115.5, 202010392197.3 and 202010737059.4, the partial names and concepts are the same as, similar to or similar to those of the above patent application, and the meanings are the same.
In an embodiment, the blockchain system may be a blockchain system configured in the chinese patent application with application number 202010392197.3, where a root chain layer in a three-layer network architecture is applied, and by using the advantages of strong capacity expansion, large throughput, small delay, high transmission speed, etc., quantum nodes are arranged every hundred kilometers, and each node calls a quantum key through an API interface, and in the process of long-distance optical fiber quantum communication, quantum states transmitted by a channel exponentially decrease with an increase in communication distance, thereby greatly limiting an effective transmission distance of quantum communication. If a quantum communication network relay station is arranged, a long-distance optical fiber channel is divided into a plurality of channels with shorter distances, so that quantum signals can not be exponentially attenuated along with the increase of the distance any more, and the distance of quantum communication is expanded. The method for realizing the quantum communication network relay station has two reliable choices: trusted relays and quantum relays.
The so-called trusted relay is actually a traditional relay under close monitoring, and the relay stores data in a traditional manner, for example, a disk, and all data that can be known by a sender and a receiver can also be known by the relay. The obvious disadvantage of trusted relay is that data is stored in the relay station, and in order to ensure the security of the relay station, the relay station needs to be ensured to be under close monitoring through manpower. In the process of long-distance optical fiber quantum communication, the quantum state transmitted by a channel exponentially decreases along with the increase of the communication distance, and the effective transmission distance of quantum communication is greatly limited. If a quantum communication network relay station is arranged, a long-distance optical fiber channel is divided into a plurality of channels with shorter distances, so that quantum signals can not be exponentially attenuated along with the increase of the distance any more, and the distance of quantum communication is expanded. The method for realizing the quantum communication network relay station generally has two options, namely trusted relay and quantum relay. The quantum key distribution protocol (TF-QKD) pushes the safe coding distance of optical fiber quantum key distribution to be more than 500 kilometers, creates a new record of optical fiber quantum key distribution, and breaks the absolute coding rate limit limited by the traditional unrepeatered quantum key distribution at the optical fiber coding rate of more than 500 kilometers. And when the distance between the two nodes is larger, the quantum satellite is selected as a credible relay.
As one of the optional embodiments of this embodiment, the method further includes: the consensus node is connected with the conversion unit, the quantum intelligent contract unit is connected with the conversion unit, and block chain data to be encrypted is used for quantum key distribution; or using the blockchain data to be decrypted for decryption. The quantum key distribution here refers to a protocol in which blockchain data is quantum-encrypted to form a quantum key.
The encryption and decryption of a quantum key are realized by using a quantum intelligent contract, meanwhile, the conversion between quantum bits and classical bits is realized by using a conversion unit, the conversion between quantum bit data in a quantum network and classical bit data in a common network is realized, and the quantum network and the common network can be fused without any barrier of data communication and exchange; here, the quantum network and the quantum communication network are synonymous and refer to a communication network that exchanges data with a qubit.
As an optional implementation manner of this embodiment, the blockchain data is an API interface address, secret level data, or a cross-link interface address.
As an optional implementation manner of this embodiment, in the quantum computer system, the quantum cloud server and the quantum virtual machine are connected to each other through a quantum channel and a common channel; the means for distributing quantum keys; the common channel is used to acknowledge the sender and the receiver.
As an optional implementation manner of this embodiment, the consensus node is connected to a national time service center, and is configured to obtain a timestamp, and send the blockchain data and the timestamp together to the conversion unit.
When at least one node in the block chain is an optical quantum switch, namely a quantum computer is used as one of the nodes of the block chain, the ultra-low access loss of the quantum computer can be utilized to realize that the quantum computer is used as one of the nodes, and the block chain is formed by networking, wherein the networking mode can refer to the networking mode of the existing block chain system, and the block chain system applied by the Chinese invention patent with the application number of 202010392197.3 can also be adopted for networking; compared with the traditional encryption method, the block chain data is encrypted by using the quantum encryption protocol, and the method has the following advantages: 1. compared with Hash encryption, the encryption process is high in speed, and time spent on block chain data encryption is greatly reduced; 2. compared with the traditional algorithm such as RSA public key cryptography, the probability of being cracked is very low; 3. due to the characteristics of the quantum secret communication network, when the quantum key is distributed to two parties or multiple parties participating in the block chain data communication by using a quantum key distribution protocol, if an eavesdropper exists, the quantum state changes, so that the error rate of the quantum key received by the two parties or the multiple parties participating in the block chain data communication is improved, and the eavesdropping behavior of the eavesdropper is easy to detect, so that the safety of the encrypted block chain data can be improved; 4. because the quantum key is distributed between two parties or multiple parties participating in block chain data communication, if any party accidentally loses the key, the block chain data can be retrieved by other communication parties, and the condition of destroying one service cannot occur; 5. after the quantum computer is added into the block chain as a node, due to the super-strong computing power, the super-fast data transmission performance and the efficient time division multiplexing function, the defects of slow block data chaining, slow consensus, low throughput and the like can be overcome, and the application occasion and the range of the block chain are expanded; in the case of occasions with huge data volume, high safety requirement and high throughput requirement, such as live broadcasting and the like, no pressure is applied at all.
Example 2

validating the recipient through a classical channel signature;
converting the blockchain data which are classical bits into quantum bits; quantum encryption is carried out through a quantum intelligent contract to form a quantum key, and the quantum key is distributed through a quantum channel;
or the like, or, alternatively,
the sender is confirmed by classical channel signature;
and receiving a quantum key distributed by a quantum channel, decrypting the quantum key by a quantum intelligent contract, and converting the quantum bit into block chain data of a classical bit.
As an optional implementation manner of this embodiment, the blockchain data is an API interface address, secret level data, or a cross-link interface address.
As an optional implementation manner of this embodiment, the API interface address is a gateway interface address or a fragmented network interface address.
As an optional implementation manner of this embodiment, the converting block chain data that is a classical bit into a qubit further includes: and acquiring a timestamp of the national time service center, and converting the timestamp and the block chain data into a quantum bit.
In a specific application example, for the same size of blockchain data, a time stamp is added for encryption through a hash algorithm related in a consensus method described in the chinese patent application with application number 202010551115.5, and the time required for forming a hash fingerprint is 1 s; and through the quantum key distribution with the timestamp in the technical scheme of the application, the time required for forming the encrypted data is 15 ms. When the same block chain data is subjected to cross-chain access and the method related to the Chinese invention patent application with the application number of 202010551115.5 is adopted, the time is consumed for 30 ms; when the method of the embodiment of the application is adopted to perform cross-chain data access, 10ms is consumed.
As an optional implementation manner of this embodiment, the protocol for performing quantum cryptography via a quantum smart contract to form a quantum key includes:
quantum key distribution protocol SARG04, Ekert91 protocol, MDI-QKD protocol, BB84 protocol, BBM92 protocol, measurement device independent quantum key distribution, or twin dual field quantum key distribution protocol (TF-QKD).
The quantum key distribution protocol SARG04 has a short transmission distance, has a very low influence on photon transmission due to environmental conditions such as noise, can encrypt a wireless channel, and is more adaptive to the IEEE802 standard protocol of the conventional network when passing through a conversion unit.
Three groups of basis vectors are used for measurement in the Ekert91 protocol, and two groups of non-orthogonal bases are used for measurement in the BBM92 protocol, so that the key generation efficiency is improved in comparison. In addition, unlike the Ekert91 protocol which uses the bell inequality to check for the presence of Eve eavesdropping, the BBM92 protocol uses a data post-processing method similar to the BB84 protocol to remove errors in the original key and information that may be revealed to Eve, resulting in a consistent security key string. The security of the BBM92 protocol is also independent of the entanglement source, since the operation of Eve on the entanglement source can be equivalently regarded as the interference on the channel caused by Eve in the entanglement source distribution process, and such a disturbance can be eliminated through the detection of error code discovery and the privacy amplification process. Furthermore, if the entanglement source and Alice's detector are put together to be the light source of Alice, then different measurements at different measurement basis vectors produce different BB84 states, and conversely any BB84 state can be produced by the above process. Thus, it appears to the outside that the light source is not different from Alice's single-photon source in the BB84 protocol. And the basis vector alignment process and the data post-processing process are the same as the BB84 protocol. Thus the BBM92 protocol is essentially equivalent to the BB84 protocol, and BBM92 can be considered an entangled version of the BB84 protocol.
