Embodiment Construction

[0080] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0081] First of all, before explaining the blockchain-based FIDO authentication method, device and system provided by this disclosure, first introduce the blockchain, which is a decentralized maintenance jointly maintained by all nodes in the blockchain network. A distributed database system, which is composed of a series of data blocks based on cryptographic methods, each data block is a block in the blockchain. According to the sequence of generation time, the blocks are linked together in an orderly manner to form a data chain, which is vividly called a blockchain. Some concepts of the blockchain network are introduced below.

[0082] The nodes in the blockchain ...

Abstract

The present disclosure relates to a blockchain-based FIDO authentication method, device, and system. The method includes: after receiving an initialization authentication request sent by a user equipment through a first application service, sending an authentication request to the user equipment, the authentication request including a challenge value, After the user equipment signs the challenge value with the authentication private key, the FIDO server receives the authentication response sent by the user equipment through the first application service. The authentication response contains the challenge value signature, and then FIDO obtains the authentication private key from the blockchain. key corresponding to the authentication public key, and use the authentication public key to verify the challenge value signature in the authentication response. It can solve the problem that the existing FIDO system is vulnerable to attack and cause information leakage, tampering or system failure, and improve the security of the FIDO system.

Description

technical field [0001] The present disclosure relates to the field of information security, and in particular, to a blockchain-based FIDO authentication method, device and system. Background technique [0002] The FIDO (Fast Identity Online, online fast identity authentication) standard is an open standard protocol proposed by the FIDO Alliance, which aims to provide an online authentication with high security, cross-platform compatibility, excellent user experience and user privacy protection. Technology Architecture. The FIDO standard completes user authentication by integrating two technologies of biometrics and asymmetric encryption, trying to end the trouble that users have to memorize and use a large number of complex passwords for many years. Two authentication protocols are proposed in the current FIDO standard: U2F (Universal 2nd Factor Protocol, Universal Second Factor) and UAF (Universal Authentication Framework, Universal Authentication Framework).
