Description
Technical Field

Background
With the popularization of 5G technology, the network has realized remote area coverage and accelerated again; but in practice, the requirements of people on speed and safety in production and life still cannot be met. The quantum computing speed is high, the signal safety is high, and the popularization process is still blocked due to the high requirement of the working environment. Existing cloud service providers may provide a basic encryption key scheme to protect cloud-based application development and services, or they may communicate these protective measures to cloud users. As cloud service providers offer schemes to support robust key management, more work needs to be done to overcome the hurdles of employing key management techniques; the protection key store must be protected as well as other sensitive data. Protection is necessary in storage, transmission and backup. Improper key storage may jeopardize all encrypted data; accessing the key store, it is necessary to limit that only certain entities requiring individual keys can access the key store, and related policies are required to manage the key store, using role separation to facilitate access control: the entity that uses a given key cannot be the entity that stores that key; finally, the keys are backed up and restored, and the loss of the keys clearly means that the data protected by the keys is lost. Although this is an efficient process of destroying data, accidental loss of keys that protect mission critical data destroys a business, so a secure backup and restore solution must be performed, which are both security problems and solutions in cloud environments, there is no "full security" solution in the market today.
When the situation of data encryption, private key encryption and the like is involved in the blockchain technology, the technology is realized by utilizing a technical means of combining symmetric encryption and asymmetric encryption, and particularly, the method is solved by a hash algorithm, which is one of core technologies for ensuring that the blockchain data cannot be tampered, but the hash encryption algorithm has a great problem that the encryption and decryption speeds are low and the time is long; in addition, if the POW algorithm is selected, the requirement on the computational effort is high, and the consensus process takes a long time, so that finally, a block is formed in a longer time, and the problem is more remarkable particularly when the uplink data is larger and the throughput is required in the application occasion; this is also one of the factors limiting the popularization and application of blockchain technology.

The present embodiment provides the subject matter related to the hardware entity part: a blockchain system, comprising: the node is used for being connected with at least one of the consensus node or the common node so as to receive, send and process the blockchain data; wherein, at least one consensus 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.

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, including but 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, a transmitting end and a receiving end are respectively arranged by the quantum virtual machine, and virtualization processing is carried out, so that the quantum computer system can be presented in various network scenes.
As one of optional implementation manners of the embodiment, the system further comprises a conversion unit, wherein the computer system is respectively connected with the quantum computer system, the quantum cloud server and the quantum virtual machine through the conversion unit;
the conversion unit is used for quantum bit of the quantum computer system, the quantum cloud server and the quantum virtual machine and classical bit unit of the computer system.
As one of optional implementation manners of this embodiment, any one of the quantum computer system, the quantum cloud server and the quantum virtual machine is used as a receiving end and a transmitting end, respectively, for performing quantum key distribution.
As one of the alternative implementation manners of this embodiment, further includes: if the common 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 one of optional implementation manners of this embodiment, if the blockchain data sent by the consensus node is encrypted data, the method further includes an encryption unit; the encryption unit is connected with the conversion unit, and the blockchain data to be encrypted are used for quantum key distribution.
As one of optional implementation manners of this embodiment, if the blockchain data received by the consensus node is encrypted data, the method further includes a decryption unit; the decryption unit is connected with the conversion unit and is used for decrypting the block chain data to be decrypted.
As one of the optional implementation manners 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 nodes of a block chain system to participate in data exchange, so that the coverage range of network signals can be enlarged, and meanwhile, the response speed of data exchange can be accelerated by means of the advantages of block chain and quantum computation, and meanwhile, the system has the advantages of data safety, stability and authenticity.
The technical scheme of the embodiment is that the Chinese patent application number is: 202010551115.5, 202010392197.3, 202010737059.4, the same partial names and concepts as in the above patent applications, are similar or analogous, and express the same meaning.
In an embodiment, the blockchain system may be a blockchain system constructed on the application of the chinese invention patent application No. 202010392197.3, and the three-layer network architecture is applied to the root chain layer, so that the advantages of strong dilatability, large throughput, small delay, high transmission speed and the like are utilized, quantum nodes are set every hundred kilometers, each node calls a quantum key through an API interface, and in the process of remote optical fiber quantum communication, the quantum state transmitted by a channel is exponentially reduced along with the increase of the communication distance, so that the effective transmission distance of quantum communication is greatly limited. If the quantum communication network relay station is arranged, a long-distance optical fiber channel is divided into a plurality of channels with short distances, so that quantum signals are not exponentially attenuated along with the increase of the distances, and the distance of quantum communication is further expanded. The mode of realizing the quantum communication network relay station is that two reliable choices correspond to: trusted relay and quantum relay.
The so-called trusted relay is a traditional relay station under tight monitoring, and the relay station stores data in a traditional manner, for example, by using a magnetic disk, and all data which can be known to a sender and a receiver are also known to the relay station. A significant disadvantage of trusted relays is that the data is stored at the relay station, which in order to ensure its security requires human effort to ensure that the relay station is under close monitoring. In the remote optical fiber quantum communication process, quantum states transmitted by a channel can be exponentially reduced along with the increase of communication distance, so that the effective transmission distance of quantum communication is greatly limited. If the quantum communication network relay station is arranged, a long-distance optical fiber channel is divided into a plurality of channels with short distances, so that quantum signals are not exponentially attenuated along with the increase of the distances, and the distance of quantum communication is further expanded. The way in which a quantum communication network relay station is implemented, we typically have two options—trusted relay and quantum relay. The quantum key distribution protocol (TF-QKD) pushes the safe code-forming distance of optical fiber quantum key distribution to more than 500 km, creates a new record of optical fiber quantum key distribution, and breaks the absolute code-forming rate limit defined by traditional unrepeatered quantum key distribution at the optical fiber code-forming rate exceeding 500 km. And selecting the quantum satellite as a trusted relay when the distance between the two nodes is larger.
As one of the alternative implementation manners of this embodiment, further includes: the quantum intelligent contract unit is connected with the conversion unit, and the quantum intelligent contract unit is connected with the conversion unit and is used for distributing the blockchain data to be encrypted; or the blockchain data to be decrypted is used for decryption. The quantum key distribution herein refers to a protocol in which blockchain data is quantum encrypted to form a quantum key.
The encryption and decryption of the quantum key are realized by utilizing the quantum intelligent contract, meanwhile, the conversion between the quantum bit and the classical bit is realized by utilizing the conversion unit, so that the quantum bit data in the quantum network is converted with the classical bit data in the common network, and the quantum network and the common network can be fused without any obstruction of data communication and exchange; here, the quantum network means a communication network in which data is exchanged by quantum bits, in accordance with the meaning of a quantum communication network.
As one of the optional implementation manners of this embodiment, the blockchain data is an API interface address, a secret data or a cross-link interface address.
As one of optional implementation manners of this embodiment, the quantum computer system, the quantum cloud server and the quantum virtual machine are connected through a quantum channel and a common channel; the method is used for distributing quantum keys; the common channel is used to acknowledge the sender and the receiver.
As one of the optional implementation manners of this embodiment, the consensus node is connected to the national time service center and is configured to obtain a timestamp and send the blockchain data and the timestamp together to the conversion unit.
At least one node in the blockchain is an optical quantum exchanger, namely when the quantum computer is used as one of the nodes of the blockchain, 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, the networking forms the blockchain, and the networking mode can refer to the networking mode of the existing blockchain system, and can also adopt the blockchain system of the China patent application with the application number 202010392197.3 for networking; compared with the traditional encryption method, the method for encrypting the blockchain data by utilizing the quantum encryption protocol has the following advantages: 1. compared with hash encryption, the encryption process is fast, so that the time spent by encrypting the blockchain data is greatly reduced; 2. compared with the traditional RSA public key cryptographic algorithm, the probability of being cracked is very low; 3. when a quantum key is distributed to two or more parties participating in blockchain data communication by utilizing a quantum key distribution protocol due to the characteristics of a quantum secret communication network, if an eavesdropper exists, the quantum state changes, so that the error rate of the quantum key received by the two or more parties participating in blockchain data communication is improved, eavesdropping behaviors of the eavesdropper are easy to detect, and therefore the safety of the encrypted blockchain data can be improved; 4. because the quantum key is distributed on two or more parties participating in the communication of the blockchain data, if any party accidentally loses the key, the blockchain data can be retrieved through other communication parties, and the situation of destroying a service can not occur; 5. after the quantum computer is added into the block chain as a node, the defects of slow block data uplink, slow consensus, low throughput and the like can be overcome due to the ultra-strong calculation power, ultra-fast data transmission performance and an efficient time division multiplexing function, so that the application occasion and range of the block chain are enlarged; in the face of huge data volume, high safety requirement and high throughput requirement, the system is completely pressureless, such as live broadcast.
Example 2
A blockchain data processing method performed by a blockchain system as in any of the embodiments 1, as shown in fig. 3 and 4, comprising:
Confirming the receiver through classical channel signature;
Converting blockchain data which is classical bits into quantum bits; carrying out quantum encryption through a quantum intelligent contract to form a quantum key, and distributing the quantum key through a quantum channel;
Or alternatively, the first and second heat exchangers may be,
Confirming the sender through classical channel signature;
and receiving a quantum key distributed by a quantum channel, decrypting the quantum key through a quantum intelligent contract, and converting the quantum bit into block chain data of classical bit.
As one of the optional implementation manners of this embodiment, the blockchain data is an API interface address, a secret data or a cross-link interface address.
As one of the optional implementation manners of this embodiment, the API interface address is a gateway interface address, or a fragment network interface address.
As one of the alternative implementation manners of this embodiment, the converting the blockchain data that is a classical bit into a qubit further includes: the timestamp of the national time service center is obtained and converted into a quantum bit together with the blockchain data.
In a specific application example, for blockchain data with the same size, adding a timestamp to encrypt the blockchain data through a hash algorithm related to a consensus method in the Chinese patent application with the application number 202010551115.5, wherein the time required for forming a hash fingerprint is 1s; by the quantum key distribution with the added time stamp, which is related in the technical scheme of the application, the time required for forming the encrypted data is 15ms. The same block chain data takes 30ms when a method related to the Chinese application patent application with the application number 202010551115.5 is adopted in the process of cross-chain access; and when the method of the embodiment of the application is adopted to carry out cross-chain data access, the time is 10ms.
As one of the optional implementation manners of this embodiment, the protocol for quantum encryption by quantum smart contract to form a quantum key includes:
Quantum key distribution protocols SARG, ekert91 protocols, MDI-QKD protocol, BB84 protocol, BBM92 protocol, to measurement device independent quantum key distribution, or twin double field quantum key distribution protocol (TF-QKD).
The quantum key distribution protocol SARG04 has relatively short transmission distance, has 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 traditional network when passing through the conversion unit.
Three sets of basis vectors are used for measurement in Ekert91 protocol, and two sets of non-orthogonal basis are used for measurement in BBM92 protocol, so that the key generation efficiency is improved compared with the measurement. In addition, unlike Ekert's 91 protocol, which uses the bell inequality to verify the existence 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, thereby 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 equivalently be regarded as interference on the channel by Eve during distribution of the entanglement source, and such a disturbance can be eliminated by detecting error code discovery and privacy amplification. Furthermore, if the entanglement source and Alice's detector are taken together as Alice's light source, then different measurements under different measurement basis vectors produce different BB84 states, and any BB84 states can be produced by the above procedure in turn. The light source is thus not visually distinguished from Alice's single photon source in the BB84 protocol. And the basic vector comparison process and the data post-processing process are the same as those of the BB84 protocol. The BBM92 protocol is essentially equivalent to the BB84 protocol, and the BBM92 can be regarded as an entangled version of the BB84 protocol.
