Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The digital asset certification method based on quantum security provided by the embodiment of the invention can be applied to an application environment as shown in fig. 1, and is applied to a digital asset certification system based on quantum security, wherein the digital asset certification system based on quantum security comprises a client and a server, and the client communicates with the server through a network. The client is also called a client, and refers to a program corresponding to a server and providing local services for the client. The server may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.
The current method for storing digital assets is that the digital assets are stored in a data center, and the method for storing the electronic storage of the digital assets, such as information abstract, on a blockchain by adopting an encryption algorithm comprises the following steps: the Sha256 algorithm is used for generating a hash digest, and the hash digest is stored and verified on the blockchain. Whereas current blockchain encryption algorithms mainly employ elliptic curve public key cryptography (ECDSA, elliptic Curve Digital Signature Algorithm) or large integer decomposition (RSA, ron Rivest, adi Shamir, and Leonard Adleman) for generating digital signatures. The world in the present stage enters the stage of rapid development of the quantum computer, and once the quantum computer is developed and mature, the existence of the large-scale general quantum computer can make many existing blockchain encryption algorithms unsafe, so that the authenticity of digital assets is difficult to ensure, and the method comprises the following steps: 1. the Grover algorithm based on the quantum computer can reduce the complexity of the search algorithm, and in theory, the Sha256 algorithm is not strong enough any more, so that the possibility of being cracked exists; 2. the current mainstream public key cryptographic algorithm can be effectively cracked by a quantum computer based on the Shore algorithm, so that after the quantum computer is popularized, the current blockchain public key algorithm is no longer safe; 3. once the security of the data asset certification is questioned, the validity of the data asset certification as evidence is greatly compromised. The application provides a technical scheme based on how to solve the problem of quantum computer cracking resistance of a blockchain encryption algorithm.
In one embodiment, as shown in fig. 2, a digital asset certification method based on quantum security is provided, and the method is applied to the server in fig. 1 for illustration, and specifically includes the following steps:
s110, acquiring digital asset information, and respectively carrying out feature extraction on the digital asset information by adopting an SHA2-512 algorithm and an SHA3-512 algorithm to respectively acquire a first feature abstract and a second feature abstract.
SHA-2 (Secure Hash Algorithm, secure Hash Algorithm 2) is a seed-cipher Hash function Algorithm standard, including SHA-224, SHA-256, SHA-384, SHA-512/224, SHA-512/256. All numbers of SHA-512 are 64 bits, and SHA-512 runs 80 encryption cycles instead of 64, and the SHA-512 initial value and constant are pulled to 64 bits.
The SHA-3 third generation secure hash algorithm (Secure Hash Algorithm 3) has a performance of 12.5cpb (cycles per byte), which uses a sponge engine to absorb an input message into an internal state, and then extrudes a corresponding hash value according to the internal state, so as to resist an attack with a minimum complexity of 2N, where N is the size of the hash. It has a wide safety margin.
Specifically, the embodiment obtains the first characteristic abstract corresponding to the digital asset information through SHA-2. Because of the irreversibility of SHA-2, even if the database is stolen, the original information of the digital asset information cannot be obtained. And similarly, obtaining a second characteristic abstract.
S120, extracting abstract related information corresponding to the first feature abstract and the second feature abstract, and packaging the first feature abstract, the second feature abstract and the abstract related information to generate packaged solid certificate information.
S130, storing the packaged fixed certificate information on a quantum security blockchain to form blockchain fixed certificate information corresponding to the digital asset information.
Specifically, the combination of quantum computers and blockchain technologies is known as quantum secure blockchain. Quantum secure blockchain is an encrypted blockchain technique, as is conventional. However, unlike conventional blockchains, these networks build on quantum arithmetic, quantum information theory, and quantum mechanics.
According to the digital asset evidence storage method based on quantum security, digital asset information is acquired, and the digital asset information is respectively subjected to feature extraction by adopting an SHA2-512 algorithm and an SHA3-512 algorithm so as to respectively acquire a first feature abstract and a second feature abstract; extracting abstract related information corresponding to the first feature abstract and the second feature abstract, and packaging the first feature abstract, the second feature abstract and the abstract related information to generate packaged solid certificate information; and storing the packed fixed certificate information to a quantum security blockchain to form blockchain fixed certificate information corresponding to the digital asset information. The method can effectively prove the time of the digital asset owner and the digital asset generation, is used for protecting the ownership of the digital asset, can effectively prove when ownership disputes occur, ensures that the digital asset is not controlled and maliciously operated by a single party, protects the interests of rights personnel, and ensures the security of the digital asset. The anti-quantum attack encryption algorithm comprises an SHA2-512 algorithm and an SHA3-512 algorithm, so that the security of the digital asset can be effectively ensured.
In one embodiment, after step S130, as shown in fig. 5, that is, after storing the packaged license information on the quantum security blockchain to form blockchain license information corresponding to the digital asset information, the method further specifically includes the following steps:
s1301, acquiring information to be verified of the digital asset, and respectively carrying out feature extraction on the information to be verified of the digital asset by adopting an SHA2-512 algorithm and an SHA3-512 algorithm to respectively acquire a first feature abstract to be verified and a second feature abstract to be verified.
S1302, extracting blockchain fixed certificate information corresponding to the digital asset information from the quantum security blockchain.
S1303, extracting a first characteristic abstract and a second characteristic abstract in the blockchain fixed pattern information, and obtaining an abstract extraction result.
And S1304, outputting prompt information of the original digital asset information of the digital asset information to be verified if the abstract extraction result is that the first feature abstract is equal to the first feature abstract to be verified and the second feature abstract is equal to the second feature abstract to be verified.
Specifically, the digital asset owner provides the digital asset to be verified in any form, and the verification center generates SHA2-512 and SHA3-512 summary information respectively according to the digital asset to be verified and verifies the information on the quantum security blockchain. If both data features based on SHA2-512 and SHA3-512 are consistent with the digest on the quantum security blockchain, the digital asset content is proved to be the original when the certificate is stored.
The method provided by the embodiment can use two methods for digital asset abstract, and simultaneously uses SHA2-512 bits and SHA3-512 bits for digital asset feature extraction, and when asset verification is carried out, the two methods are safe in quantum level theoretically, and double-factor verification assurance is provided.
In a specific embodiment, in step S1303, i.e. after obtaining the summary extraction result, the method further specifically includes the following steps:
s3011, outputting prompt information that the information to be verified of the digital asset and the digital asset information are different data if the abstract extraction result is that the first feature abstract is different from the first feature abstract to be verified or the second feature abstract is different from the second feature abstract to be verified.
In this embodiment, as long as the digest extraction result is that the first feature digest is different from the first feature digest to be verified and the second feature digest is different from the second feature digest to be verified, it may be determined that the output digital asset information to be verified is not the original of the digital asset information.
In a specific embodiment, in step S130, the method stores the packaged license information onto the quantum security blockchain to form blockchain license information corresponding to the digital asset information, which specifically includes the following steps:
s131, signing the packaged fixed certificate information by adopting a crystal-Dilithium digital signature algorithm, and storing the signed fixed certificate information on a quantum security blockchain to form blockchain fixed certificate information corresponding to the digital asset information.
In particular, the crystal-Dilithium digital signature algorithm can achieve better balance in terms of security, public and private key size and calculation speed. Meanwhile, under the same security intensity, the public and private key size scheme of the grid password is smaller, the calculation speed is faster, and the method is more suitable for multiple application scenes.
The embodiment can upgrade the blockchain signature algorithm by adopting a crystal-Dilithium digital signature algorithm to become a quantum security blockchain, thereby being capable of resisting the cracking of a quantum computer.
In a specific embodiment, after step S120, that is, after generating the packaged certificate information, the method further specifically includes the following steps:
s1201, storing the packaged fixed certificate information to a data center to form packaged certificate storage information corresponding to the digital asset information.
Specifically, storing the feature abstract information, the time information and other related description information into a data center; the digital asset owner may self-save the digital asset in any manner.
In one embodiment, after step S130, as shown in fig. 4, that is, after storing the packaged license information on the quantum security blockchain to form blockchain license information corresponding to the digital asset information, the method further specifically includes the following steps:
s3021, if the digital asset information is subjected to data updating, generating digital asset updating information.
S3022, carrying out feature extraction on the digital asset updating information by adopting an SHA2-512 algorithm and an SHA3-512 algorithm respectively to obtain a first updating feature abstract and a second updating feature abstract respectively.
S3023, extracting abstract related update information corresponding to the first update feature abstract and the second update feature abstract, and packaging the first update feature abstract, the second update feature abstract and the abstract related update information to generate packaged solid certificate update information.
S3024, storing the packaged fixed certificate updating information on the quantum security blockchain and storing the packaged fixed certificate updating information in a correlated mode with the blockchain fixed certificate information.
Specifically, even if the initial digital asset information changes, the packaged fixed certificate updating information is finally generated on the blockchain, and the packaged fixed certificate updating information is stored in association with the blockchain fixed certificate information corresponding to the initial digital asset information, so that the original fixed certificate information corresponding to the initial digital asset information is permanently stored, and the authenticity and the effectiveness of storage are ensured. Even if the initial digital asset information is verified, the quantum secure blockchain can still provide corresponding blockchain certification information, which is also determined by the non-tamper-evident nature of the quantum secure blockchain itself.
In a specific embodiment, in step S120, extracting summary related information corresponding to the first feature summary and the second feature summary specifically includes the following steps:
s121, extracting time information and related description information respectively corresponding to the first feature abstract and the second feature abstract.
Specifically, the summary related information includes feature summary information, time information, and other related description information.
According to the digital asset evidence storage method based on quantum security, digital asset information is acquired, and the digital asset information is respectively subjected to feature extraction by adopting an SHA2-512 algorithm and an SHA3-512 algorithm so as to respectively acquire a first feature abstract and a second feature abstract; extracting abstract related information corresponding to the first feature abstract and the second feature abstract, and packaging the first feature abstract, the second feature abstract and the abstract related information to generate packaged solid certificate information; and storing the packed fixed certificate information to a quantum security blockchain to form blockchain fixed certificate information corresponding to the digital asset information.
