Technical Field
The invention relates to the technical field of a data file fragment encryption mode, in particular to a data file fragment encryption type chaining method.
Background
The block chain is a technical system which is maintained by multiple parties, stores data in a block chain structure, uses passwords to ensure transmission and access safety, and can realize consistent storage, falsification and deletion of the data, so the block chain becomes a main technical expression form of the current financial technology (Fin-Tech), and a large number of emerging projects based on the block chain technology begin to conduct information conduction based on the block chain.
With the rapid development of network applications, the amount of network information data is larger and larger, and mass data storage becomes important. The traditional file system can not meet the requirements of high capacity, high reliability, high performance and the like of the existing application, and the application of the distributed file system is widely regarded to meet the new requirements. Data fragmentation generally calculates Key distribution by using keys or hash values of keys, and several common data fragmentation methods include number segment division, modulus extraction, retrieval table and consistent hash algorithm.
The prior technical scheme is as follows:
an existing block height tile-based data storage method based on a block chain is characterized by comprising the following steps: the method comprises the steps of automatically reproducing a creation block process, a block header multi-hash storage process and a world state initialization process at a certain block height. The block chain includes two block types, a normal block and a century creation block; the common block records transaction information; the created block records the height of the next created block and the current latest world state; the first created block of the created blocks is a basic block, and no other block header is hashed and does not point to; all other created blocks of the created blocks record two block head hashes, one is a last block and the other is a last created block, and two ways of tracing to the first created block can be provided; when the block chain height reaches a preset block height, a next block can automatically generate a new created block; initializing the latest world state as the initial state of the new world when the latest creating block appears; both paths can fully check the correctness and completeness of the transaction; the normal blocks before the newly created block may be deleted.
The prior art scheme has the following defects:
most of the existing file chaining methods adopt direct data chaining, files occupy a large storage space, transmission cost is high in the communication process, and the risk of transmission interruption is high. Or after the file is fragmented, the chain is still arranged in a normal sequence, and encryption is not performed, so that the data security problem exists.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the technical defects and provide a data file fragment encryption type chaining method, which can solve the problems of high storage cost and communication cost caused by overlarge file volume stored on a block chain, and can increase cracking difficulty and solve the problem of data security based on the distributed characteristic of the block chain.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a data file fragment encryption type chaining method comprises the following steps:
the method comprises the following steps: the method comprises the steps of distinguishing structured data and unstructured data, storing the structured data in a knowledge graph mode, storing the data under a block chain platform, uploading file fragments to a distributed file center through the unstructured data, disordering the sequence, encrypting the file fragments through a private key, and chaining the file fragments;
step two: when data fragmentation is carried out, a fragmentation sharing mode is adopted, the size of the fragments is calculated by using a factorial algorithm, the difficulty coefficient can be dynamically adjusted, and the difficulty coefficient is changed according to the change of the number of the fragments and is determined by an exponential control cost mode;
step three, collecting: encrypting and mixing the sliced data to generate a random value, inserting the random value into a block structure, and disturbing the block arrangement mode;
step four: after the file is encrypted and stored, the data is identified and accessed by adopting a Mercker tree mode.
Compared with the prior art, the invention has the advantages that: the file is divided into fragments and linked up after encryption, so that encryption protection can be provided for the file.
The efficiency of file upload and communication can be improved, the storage cost and the transmission cost in the communication process are reduced, and the risk of file transmission interruption in the transmission process is reduced.
Based on the distributed characteristic of the block chain, the on-line and off-line of any storage node have no influence on the front-end service, the cracking difficulty is increased, and the data security can be better guaranteed.
