AI Technical Summary

Technical Problem

Existing interception strategies at cross-border communication gateways are unable to effectively distinguish between legitimate and illegitimate calls, resulting in the wrongful interception of normal communications and failing to prevent number spoofing, which affects international business communication and emergency handling.

Method used

A trusted identity-based authentication mechanism is adopted, which generates an identity token through the calling user terminal and performs real-time signature verification at the gateway. If the signature verification is successful, the call is allowed; otherwise, it is blocked using code number rules or call behavior policies.

Benefits of technology

It enables online verification of the caller's true identity, accurately allows legitimate calls, avoids false blocking, and improves the availability and anti-fraud capabilities of cross-border communications.

Abstract

This invention discloses a method, device, and medium for enabling cross-border communication at a gateway based on trusted identity, relating to the field of trusted communication technology. The method includes: when a calling user terminal initiates a cross-border communication call, it generates an identity token based on pre-set trusted identity credentials and uploads it to a token message transmission service; after the call is transmitted to the gateway, the gateway executes a trusted authentication strategy, obtains the corresponding identity token from the token message transmission service, and verifies the signature; if the signature verification is successful within a preset time, the call is enabled; if the signature verification fails or times out, the call is processed based on code number rules or call behavior interception strategies. This invention achieves dynamic online authentication of the calling party's identity by enabling real-time signature verification of the cryptographic identity token at the gateway, overcoming the shortcomings of interception based solely on static code number rules. While ensuring smooth cross-border communication, it maintains basic anti-fraud capabilities using traditional strategies, achieving a balance between accurate enabling and effective interception.
