Abstract

The invention provides a block chain security management system and method. An authority is responsible for bookkeeping qualification of each bookkeeper; each bookkeeper packs a public key thereof andinformation to be recorded in the block chain to a new block, thereby signing the information by using a private key of the new block and then publishing the signed information; each node participating the block chain only records the block possessing the bookkeeping qualification and having the valid digital signature in the chain. The system effectively supervise the user and het bookkeeper identity by using the authority, the limitation on the bookkeeping qualification of the bookkeeper prevents a bad bookkeeper from interfering the normal operation of the block chain system, and the stability and the security are improved.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a security management system and method for blockchain. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed accounting system. Structurally, a block usually includes two parts: a header and a body. The block header is used to link to the previous block, and the transaction information recorded in the block body is all the value exchange activities that occurred after the previous block was formed and before the block was created. This feature ensures the integrity of the database. The blockchain adopts a distributed bookkeeping method, and each transaction is only valid if it is included in the blockchain by the bookkeeper (hereinafter referred to as on-chain). Transaction accounting is completed by multiple no...
