China News Client, Beijing, May 14 (Reporter Wu Tao) Previously, the three major operators declared that users do not change cards or numbers when using 5G services. But on the 13th, a white paper issued by China Telecom pointed out that the existing 4G card cannot meet the information and security requirements of the 5G network.

China Telecom ’s “White Paper on 5G SA Security Enhanced SIM Card” (hereinafter referred to as the “White Paper”) shows that users are currently accessing 5G networks through 4G cards, and existing 4G cards lack new functions and new ones defined in the 5G standard. Card files and services, and user identity data are transmitted in clear text during the communication process. The location information is not precise enough to meet the information and security requirements of the 5G network.
According to the "White Paper", the single authentication authentication mode cannot meet the needs of operators to develop third-party business applications; NATIVE's card architecture, with the further expansion of 5G industry applications, cannot respond well to the requirements of various business development, users enjoy Less than 5G network brings new experience and business services.
The "White Paper" also pointed out that according to the 5G development strategy and the characteristics of the 5G network, a new 5G SA security enhanced SIM card (referred to as 5G card) is needed as an identification module for accessing the 5G network and a support carrier for loading various 5G industry applications. The 5G card implements new features including user identity privacy protection and GBA third-party application authentication. It provides security for user data and business applications and will help operators develop third-party mobile application services.
According to reports, the communication function is a basic function of 5G cards, providing access to telecommunications operators' 5G network capabilities in order to provide users with 5G voice, SMS, data and other services.
According to China Telecom, the 5G card has added 5G mobility management, user identity privacy protection, enhanced security certification, GBA certification, 5G access control, 5G USAT events, etc. to meet the requirements of 5G users and diversified 5G mobile services. Features.
"White Paper" pointed out that the user identity information in the 4G network is clearly transmitted in the communication process. The 5G network uses the SUCI encryption calculation function in the 5G card to correct it. The user's identity can only be encrypted and transmitted in the 5G network by SUCI.
"Various connected devices in the 5G network, such as industrial Internet of Things devices, personal terminals, refrigerators, TVs, air conditioners and other household devices, each device has an identity, and 5G can protect the identity of the access user through the SUCI computing solution. Privacy to avoid being tracked and attacked. "
In addition, in the intelligent medical system and intelligent transportation, business information such as patient medical records, prescriptions and treatment plans, vehicle positions and driving trajectories are high-security data related to life safety. In 4G networks, hackers may lock the user's identity through tracking Attacking this part of user privacy data, the 5G network SUCI scheme avoids the tracking of user identity and reduces the possibility of attacking critical data from user identity information.
"In the 4G era, various mobile Internet applications on the user's mobile terminal use the obtained user identity information to analyze big data of user behavior, and illegal gains can be obtained through user data," the White Paper said, but in the future through SUCI The privacy protection scheme can avoid the leakage of the user's identity, and further guarantee the safety of the user's behavior data.
