Trusted communication system and method

Abstract

The invention discloses a trusted communication system and method. The system comprises a governance service center, a trusted communication service platform, a certificate issuing mechanism, the security module and a trusted identity terminal. The method comprises the following steps: S1, generating an identity token while a calling terminal makes a video initiating request; S2, transmitting theidentity token of the calling terminal to a called trusted identity APP video terminal; S3, the called terminal obtaining the identity token of the calling party from the 5G network slice for decryption, and obtaining a certificate; S4, the called terminal pushing the certificate to the trusted communication service platform for certificate verification through a 5G network slicing technology; andS5, selecting answering, and performing video call between the calling terminal and the called terminal. The trusted communication system and method provided by the invention comprise a certificate authentication mechanism, a reliable protection effect is provided for identity authentication, and a virtual network URLLC channel of a 5G network slicing technology is used, so that the low time delay of identity authentication can be ensured, and the security of a video call is also ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a trusted communication system and method. Background technique [0002] With the popularity of smart phones and the maturity of network technology, more and more mobile users choose to access the Internet through mobile user terminals. increasingly favored by people. However, along with the popularization of video chat, there have also been many fraudulent behaviors through video calls, seriously affecting the communication and property safety of netizens. In particular, with the development of AI technology, criminals can use AI technology to imitate human voice with sound synthesis technology, and use AI face-changing technology to disguise as a designated human face, so that the receiver of the video cannot distinguish the authenticity, and then use The means of committing a crime of fraud. [0003] Therefore prior art needs to be improved. Contents of the inventi...
