Description
Technical Field
The invention relates to a block chain strengthening method, and belongs to the technical field of block chain application.
Background
All third-party electronic evidence storage platforms which can obtain judicial approval nowadays utilize the hash encryption technology. However, in the evidence of block chain evidence, the hash encryption is only one of the security measures, and in addition, there are a consensus mechanism and two core underlying technologies of decentralized storage, which are also the most essential differences between the common electronic evidence of block chain.
The block chain technology is an information system architecture based on a distributed system and with public shared accounts as a core. The block chain technology can directly incorporate the hash value digest which is locally generated and used as the source file evidence into a certain block of the block chain, the block fixedly stores the source file evidence through a hash function, and the hash digest number of the previous block is also incorporated into the next block when the next block is newly generated, so that the block chain is formed in a delayed mode. In the process, if a certain data is tampered, all block data on the chain is to be changed, under the guarantee of a consensus mechanism that the whole chain is tightly buckled, the change of electronic evidence caused by the fact that a certain hash function is broken can be completely avoided, and decentralized distributed storage is also the core advantage of the block chain.
However, in actual work, when the current operating system based on the block chain runs, the data encryption operation often uses the international tube encryption count, which can satisfy the data encryption requirement, but also easily causes the data to be decoded maliciously, thereby causing the data to be lost and tampered, and the data encryption operation cannot be flexibly performed according to the actual work requirement, which causes great inconvenience to the actual work.
Therefore, in order to solve this problem, it is necessary to develop a block chaining strengthening method to meet the needs of practical use.
