Different from the traditional method of directly writing a large file into a block chain, the embodiment can provide certain storage resources and network loan resources by deploying the storage nodes, and reduces the situation of resource consumption when the target file is stored in the block chain and waits for use.
the target file is randomly split, the file can be prevented from being tampered, the split target file is divided into a plurality of sub-files, the plurality of sub-files are randomly and relatively uniformly stored in all storage nodes of the block chain, and distributed storage of the target file can be achieved.

and when the user needs to download the target file, triggering a second operation instruction, wherein the user can use the unique identifier returned in the steps as a certificate to acquire the target file. In the process of acquiring the file, the uniqueness and the integrity of the target file can be ensured by calculating the hash of the target file and carrying out file verification based on the hash value, and meanwhile, because all the storage nodes are in a distributed deployment mode, a user does not need to designate a single source when acquiring the target file, so that the possibility of file loss and loss is reduced
And step 104, downloading the target document from the block chain after the document verification is passed.
In one embodiment, in response to the second operation instruction, determining a hash value of the target file according to the unique identifier, and performing file verification based on the hash value includes:
step 1041, responding to the second operation instruction, and determining a hash value of the target file according to the unique identifier;
and 1042, verifying and comparing the hash value with the file fingerprint stored in the block chain.
The hash value of the block chain can uniquely and accurately identify one block, the hash value of the block can be acquired by any node in the block chain through simple hash calculation, and the calculated hash value is unchanged, which means that the information in the block chain is not tampered, so that the hash value is checked and compared with the file fingerprint stored in the block chain, and the uniqueness and the integrity of the target file can be verified.

When the user selects the national crypto mode, a higher level of encryption algorithm may be used to increase the security level of the user's use.
In one embodiment, the encryption algorithm comprises an asymmetric encryption algorithm, and determining the current encryption algorithm according to the encryption mode selected by the user comprises:
in step 2011, when the encryption mode selected by the user is the standard encryption mode, it is determined that the current encryption algorithm is the asymmetric encryption algorithm.
Wherein, the asymmetric encryption algorithm needs to use two keys: the user public key and the user private key are a pair, if the public key is used for encrypting data, only the corresponding private key is used for decrypting the data, the asymmetric encryption algorithm does not require that two communication parties transmit the key in advance or have any agreement to finish secret communication, the key management is convenient, and counterfeiting and repudiation can be prevented. Of course, when the encryption mode selected by the user is a national encryption mode, the current algorithm is determined to be a custom algorithm, wherein the custom algorithm comprises a country or region specific encryption algorithm, and thus, the encryption security can be improved by using an encryption algorithm with a higher encryption level.
As shown in fig. 3, in one embodiment, the method further comprises:
When a new related party participates in the method or an original related party is willing to provide new resources, a third operation instruction can be triggered to provide a certificate acquisition channel before the node is established for the new resources, and then a storage node is established according to the unified authentication certificate to acquire files required by the storage node. Of course, according to the service requirement, the operations of stopping, destroying, etc. can be executed for the storage node, and the resource is released immediately.

randomly splitting the target file, and dispersedly storing the split target file in all storage nodes of the block chain;
responding to a second operation instruction, determining a hash value of the target file according to the unique identifier, and performing file verification based on the hash value;
and after the file passes the verification, downloading the target file from the block chain.
2. The method according to claim 1, wherein the determining, in response to the second operation instruction, a hash value of the target file according to the unique identifier and performing file verification based on the hash value comprises:
responding to a second operation instruction, and determining a hash value of the target file according to the unique identifier;
and checking and comparing the hash value with the file fingerprint stored in the block chain.
3. The method according to claim 1 or 2, characterized in that the method further comprises:
determining a current encryption algorithm according to an encryption mode selected by a user, wherein the encryption mode comprises a standard secret mode or a national secret mode;
and according to the current encryption algorithm, carrying out verification operation by using a corresponding encryption mode.
4. The method of claim 3, wherein the encryption algorithm comprises an asymmetric encryption algorithm, and wherein determining the current encryption algorithm based on the user-selected encryption mode comprises:
and when the encryption mode selected by the user is a standard encryption mode, determining that the current encryption algorithm is the asymmetric encryption algorithm.
5. The method according to claim 1 or 2, characterized in that the method further comprises:
generating and distributing a unified authentication certificate in response to the third operation instruction;
and creating a storage node according to the unified authentication certificate, and executing a first operation on the storage node, wherein the first operation comprises at least one of starting, stopping, state checking, destroying and updating.
6. The method according to claim 1 or 2, further comprising at least one of:
deploying a plurality of nodes in the same operating system, and connecting the corresponding nodes according to user attributes, wherein the user attributes comprise the authority of a user and the requirements of the user;
alternatively, the first and second electrodes may be,
acquiring and binding a user public key;
and verifying the access request of the user based on the user public key and a user private key corresponding to the user public key.
7. The block chain-based security information evidence storage management system is characterized by comprising a large file storage and management subsystem, wherein the large file storage and management subsystem comprises:
the file uploading module is used for uploading a target file to a target storage node of the block chain and returning a unique identifier, wherein the unique identifier is used for representing a unique certificate of the target file acquired by a user;
the file processing module is used for randomly splitting the target file and dispersedly storing the split target file in all storage nodes of the block chain;
the file checking module is used for determining the hash value of the target file according to the unique identifier and checking the file based on the hash value;
and the file downloading module is used for downloading the target file from the block chain after the file passes the verification.
8. A block-chain-based security information credentialing management device comprising a memory and a processor, said memory storing a computer program, characterized in that said processor implements the steps of the method according to any one of claims 1 to 6 when executing said computer program.
9. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method of any one of claims 1 to 6.
10. A computer program product comprising a computer program, characterized in that the computer program realizes the steps of the method of any one of claims 1 to 6 when executed by a processor.
