Abstract

The invention provides a whole-network unified online authentication method and system based on a block chain. The method comprises the following steps that N servers are arranged in the whole networkdivided into S areas, and at least one server is arranged in each area to serve as a data storage node, wherein other servers are set as authentication service nodes; a first data storage node receives first user request information sent by a user side; the first data storage node generates first response information according to the first user request information, and sends the first response information to the user side; the first data storage node acquires block chain information corresponding to a first user according to the first response information, stores the block chain information corresponding to the first user in a block, and sends the block chain information corresponding to the first user to other data storage nodes; and the first authentication service node receives a second user request sent by the user side, and verifies the second user request.

Description

technical field

[0001] The present invention relates to the field of communications, in particular to a blockchain-based unified online authentication method and system for the entire network. Background technique

[0002] Under the public key cryptography system, the public key digital signature technology needs to rely on the CA certificate issued by the public key infrastructure (PKI) to bind the identity of the entity and the public key to ensure the authenticity of the public key of the entity. Binding the user's public key and user identity in the form of a public key certificate forms a mature solution to network security issues. However, PKI introduces a trusted third-party CA, which brings the cost of certificate management, storage and calculation:

[0003] 1. The issuance, issuance, acquisition, verification, and revocation of certificates are complicated procedures;

[0004] 2. An online certificate directory is required to provide users with certificate downlo...
