Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] A unified identity authentication method based on the block chain, the block chain includes a primary node (kgc) and the secondary node, the main node is equivalent to the miners in the block chain, the secondary node is the user in the block chain, when two Before the user is transaction, it is necessary to effectively and reliably verify each other, and it is not possible to disclose your identity. In order to realize the security and confidentiality of the identity authentication of the transaction in the block chain, it provides the following methods:

[0027] Step 1, the first node A and the second node B initiate and create a transaction N AB (Ie the transaction information required between A and B), both sides verify the transaction N AB The legality (including the price of the transaction), after the certification of both parties, bo...

Abstract

The invention discloses a unified identity authentication method based on a block chain, and belongs to the technical field of block chains. The method comprises the following steps: after receiving a transaction request, all main nodes jointly generate two verification keys and respectively send the two verification keys to a primary node A and a secondary node B, and after receiving the transaction request, each main node respectively generates two keys containing identity information of the main node and respectively sends the two keys to the primary node A and the secondary node B; the first node A and the second node B respectively generate a key eA and a key eB according to respective ID numbers and transaction nAB information, the first node A generates an authentication key SA according to the key eA and the received verification key, the second node B generates an authentication key SB according to the eB and the received verification key, and the SA and the SB are mutually sent to verify whether the identities of the SA and the SB are legal or not. According to the invention, identities of two transaction parties in the block chain can be effectively authenticated, and the security of the transaction and the confidentiality of node identities are ensured at the same time.

Description

Technical field [0001] The present invention relates to the field of block chains, and more particularly to a unified identity authentication method based on a block chain. Background technique [0002] Block Chain Technology is built on the Internet, using P2P, distributed storage, and distributed key ideas, the data blocks arranged in time sequential order into a particular data structure in the chain. The chain structure of the block chain uses an encrypted signature to ensure that the links of the data are not tampered or forged. It can store a large number of optical time series fingerprint data. The block chain can be used as a data log database, and the database is shared by the network node. Unlike the existing database, when the node updates the data, they submit data records, and ensure consistency between nodes data, and after the consistency is determined, the recording of the block chain will not be changed or delete. The block chain is a distributed book technology:...
