Abstract

The invention provides a cloud secret key authentication system based on a public key algorithm. The cloud secret key authentication system comprises a terminal device, a secret key and certificate management subsystem, a service subsystem. The terminal device authenticates the identity of a user and forwards a service request after authentication succeeds. The secret key and certificate management subsystem is located in a cloud server, and stores user secret keys and digital certificates. The service subsystem analyzes a user authentication result and a risk authentication result. When receiving a response instruction, the secret key and certificate management subsystem provides the terminal device with the user secret key and the digital certificate corresponding to the user. The terminal device receives and stores the user secret key and the digital certificate and performs payment with the service subsystem by using the user secret key and the digital certificate. The cloud secret key authentication system authenticates the identity of the user by using a biological recognition module, uses the risk authentication and biological information authentication of a service provider, and may terminate a high-risk transaction according to the risk authentication and biological information authentication of a service provider so as to avoid losses.

Description

technical field [0001] The invention relates to the technical fields of mobile Internet and cloud computing, in particular to a cloud key authentication system based on a public key algorithm. Background technique [0002] With the popularity of mobile Internet devices such as smartphones and tablets, current consumers need to frequently conduct personal financial transactions such as consumer payments, transfers (such as WeChat red envelopes), and wealth management on mobile smart devices. When conducting financial transactions such as payment and transfer on mobile phones, there is a lack of effective means of identity authentication and non-repudiation using digital signature technology. Smart password keys and smart IC card devices such as Bluetooth, audio code, and NFC can theoretically be used in the above scenarios, but they are limited by the variety of mobile phone models, poor compatibility, and cumbersome personal carrying and use, resulting in poor user experienc...
