Embodiment 1

[0021] Such as figure 1 A heterogeneous cross-chain interaction and authentication method of blockchain is shown, including the following steps:

[0022] Step 1: Encryption processing of data, encrypting the data through an algorithm to obtain the encrypted data, and waiting for the next step of processing;

[0023] Step 2: Heterogeneous multi-chain parallel method processing, the encrypted data in step 1 is processed by heterogeneous multi-chain parallel method, waiting for the next step of processing;

[0024] Step 3: Blockchain processing. The data in Step 2 are allocated to multiple different blockchains, and each group of data is authenticated in the blockchain through block allocation and data signature.

[0025] Such as figure 2 As shown, this embodiment includes four sets of data: data A, data B, data C, and data D, and data A, data B, data C, and data D are respectively encrypted using an encryption algorithm and a consensus algorithm to obtain encrypted data Data...

Embodiment 2

[0027] As shown in Embodiment 1, a heterogeneous cross-chain interaction and authentication method of a blockchain differs only in that in step 1, data encryption processing includes encryption algorithm processing and consensus algorithm processing, wherein encryption algorithm processing includes encryption algorithm processing The advanced encryption standard algorithm is adopted, and the consensus algorithm in the consensus algorithm processing uses the Byzantine fault-tolerant algorithm.

Embodiment 3

[0029] A heterogeneous cross-chain interaction and authentication method of blockchain as shown in Example 1, the only difference is that the heterogeneous multi-chain parallel method processing in step 2 includes data interaction strategy processing and data validation strategy processing, by adopting The data interaction strategy processing realizes the data collection and interaction of each sub-chain of the blockchain; by adopting the data verification strategy processing, it realizes the verification of all transactions according to the comparison between the hash value and the Merkle tree stored locally. Data security is guaranteed.

Abstract

The invention discloses a heterogeneous cross-chain interaction and authentication method of a block chain. The method comprises the steps of data encryption processing, heterogeneous multi-chain parallel method processing and block chain processing, an encryption algorithm and a consensus algorithm are adopted for data encryption processing, encrypted data are processed through a heterogeneous multi-chain parallel method and distributed to different block chains respectively, block division and data signature are carried out in the block chains, and data authentication is completed. The heterogeneous cross-chain interaction and authentication method of the block chain ensures the security of transaction data, and has the advantages of security and wide practicability.

Description

technical field [0001] The invention relates to an interaction and authentication method, in particular to a block chain heterogeneous cross-chain interaction and authentication method. Background technique [0002] Among the many problems faced by the blockchain, the interoperability between the blockchains greatly limits the application of the blockchain. The traditional method of cross-chain interaction is to extract multi-source data from each chain, and then provide data interaction services in a unified manner. There must be a process of extraction, cleaning, conversion, and merging, and the integration cost is quite high. With the number of chains and on-chain With the rapid increase of data, it is actually very difficult to perform large-scale data interaction. [0003] Therefore, the need to establish an on-demand heterogeneous cross-chain interaction technology is the key to realizing value interconnection and a bridge for the outward expansion and connection of b...
