AI Technical Summary

Technical Problem

In existing technologies, the token request process involves a large number of unnecessary ascending authentication steps, resulting in a waste of system resources and time, and low efficiency.

Method used

By storing the private key of the encryption key pair in the user device and using the public key to verify the proof message sent by the token requester, the binding between the user device and the token service computer is achieved, reducing redundant authentication steps.

Benefits of technology

It simplifies the token request process, reduces system resource consumption and time, improves the efficiency of interactive processing, and maintains security and reliability.

Abstract

A method is disclosed. The method includes receiving a first attestation message from a user device storing a private key of a public-private key pair, the first attestation message including a first attestation packet, the public key, a user device identifier of the user device, and a credential. The method also includes binding the credential to the user device identifier and transmitting the first attestation packet to a token service computer. The token service computer previously bound a first token from a first token requestor interacting with the user device to the user device identifier. The method includes receiving a second attestation message including a second attestation packet from a second token requestor interacting with the user device, verifying the second attestation packet using the public key, and transmitting verification data to the second token requestor. The second token requestor transmits the verification data to the token service computer.
