Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] To facilitate the understanding of the technical solution of the present invention, the following concepts are set forth:

[0046] In the blockchain system, there are many ways to generate public / private keys and addresses. The method proposed in this patent is based on the mode that the public key can be derived from the address.

[0047] Currently, the biggest problem most blockchain companies face is the inability to store large amounts of data on their own chains. So far, all data blocks are only a few hundred GB, and the Ethereum programmable blockchain project can only execute and store small contract codes, and the development of DAPP is greatly restricted. Using distributed storage technology to solve the storage bottleneck is one of the feasible solutions.

[0048] A distributed storage system stores...

Abstract

The invention discloses a hierarchical encryption method and system based on a block chain and distributed storage. The hierarchical encryption method based on the block chain and the distributed storage comprises the following steps: acquiring address data of a receiving user, and generating a corresponding public key according to the address data; encrypting sending information by using the public key; enabling the receiving user to obtain the encrypted sending information through a preset channel and decrypte the sending information by using a private key of the receiving user; and acquiring address data of another receiving user, generating another corresponding public key according to the address data, and entering the step of encrypting the sent information by using the public key again. According to the technical scheme, the technical problems that an encryption method in the related technology cannot meet the requirement for privacy protection of a user, and storage space is inconvenient to save are solved.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a hierarchical encryption method and system based on blockchain and distributed storage. Background technique [0002] The characteristics of blockchain technology include transparency, sharing, traceability, and extensive participation. "Transparency" means expanding the dimension of information exposure; "sharing" means increasing the location of data storage, and all nodes can store data; "traceable" means that user privacy data storage may be permanent, not after a period of time Just delete and discard, prolong the privacy storage time, and it will be difficult to be forgotten; "Extensive participation" means that the blockchain, as a distributed network, must have consensus among all parties. At this time, there may be short boards, while open network environments are more prone to incorporation of untrusted roles. [0003] In related technologies, trust is est...
