Embodiment Construction

[0021] In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.

[0022] The blockchain information encryption method of this embodiment can encrypt multi-user interaction information so that it can be applied to blockchain technology. The blockchain information encryption method of this embodiment includes an original encryption step, a key generation step and a secondary encryption step. The original encryption step and the key generation step are not in any order and can be performed at the same time, while the secondary encryption step needs to wait until the other two steps are completed.

[0023] The purpose of the original encryption step is to first encrypt the original text. The information encryption method of this embodiment can be applied to multi-person interaction and social interaction, and the original ...

Abstract

The invention relates to a block chain information encryption method, a decryption method, a storage method and device. The block chain information encryption method is used for encrypting multi-userinteractive information. The block chain information encryption method comprises the following steps: an original encryption step of encrypting the original text by a random key to obtain a ciphertext; A key generation step of generating a pair of random public keys and a random private key, and then calculating the random private keys with more than one user public keys by using an encryption algorithm to obtain separate common keys respectively; A secondary encryption step of separately encrypting the random key through each common key to obtain a separate identification key; wherein, the user public key, the common key and the identification key are one-to-one correspondence. The invention can realize the secrecy and decryption of multi-user interactive forms such as group chat, forum,micro-blog, etc., so that more extensive social function can be realized on the block chain, high encryption security can be achieved, and good user experience can be maintained at the same time.

Description

technical field [0001] The present invention relates to block chain encryption technology, in particular to a block chain information encryption method, decryption method, storage method and device. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing method for programming and manipulati...
