Embodiment approach

[0133] Setting an asymmetric key pair corresponding to the first node and the second node; when encrypting the key, encrypting the key using the public key of the asymmetric key pair of the first node and the second node respectively, Generate corresponding first key ciphertext and second key ciphertext;

[0134] Correspondingly, the key decryption module decrypting and obtaining the key in the blockchain data in an agreed manner includes: using the private key of the asymmetric key pair of the second node to decrypt the second key ciphertext, Obtain the key in the blockchain data.

[0135] The blockchain data processing method provided by this application can be realized by the processor executing corresponding program instructions in the computer, such as using the c++ language of the windows operating system to realize on the PC side, or other corresponding application designs such as Linux, android, and iOS systems Language implementation etc. In another embodiment of a ...

Abstract

The invention discloses a blockchain data processing method, device and system. The blockchain data processing method comprises that a first node identifies whether received block information needs privacy protection processing; if the received block information needs privacy protection processing, a secret key of a plaintext encryption algorithm is generated, the block information is encrypted by means of the plaintext encryption algorithm employing the secret key, and encrypted block information is generated; the secret key is encrypted in a stipulated way, a secret key ciphertext is generated, the stipulated way comprises an algorithm through which a second node associated with the first node in the first node and the blockchain encrypts and decrypts the secret key ciphertext according to a preset mode; and data including the encrypted block information and the secret key ciphertext is stored a corresponding block of the blockchain as blockchain data. According to each embodiment of the invention, information data stored in the blockchain can be encrypted, so that only specific members can decrypt and check the information data, and the aim of carrying out privacy protection on special transaction information is achieved.

Description

technical field [0001] The present application belongs to the technical field of computer data processing, and in particular relates to a block chain data processing method, device and system. Background technique [0002] The blockchain technology often used in the industry is built on a peer-to-peer (P2P) network, using a chained data structure to verify and store data, using a distributed node consensus algorithm to generate and update data, and using cryptography to ensure data transmission and Access security, a new distributed infrastructure and computing paradigm that uses smart contracts composed of automated script codes to program and manipulate data. [0003] The blockchain is a tamper-proof, shared digital ledger used to record transactions in a public or private peer-to-peer network. A node in the blockchain distributes the ledger to all member nodes in the network. Permanently records the history of asset transactions that occur between peer nodes in the netwo...
