Title:
METHOD AND DEVICE FOR PROTECTING SENSITIVE USER PLANE TRAFFIC
Document Type and Number:
WIPO Patent Application WO/2021/221489
Kind Code:
A1
Abstract:
Disclosed herein are a communication technique for merging, with an IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. Embodiments herein disclose a method of protecting sensitive user plane traffic in an User Equipment (UE) (100), the method comprising: transmitting, to a network (200), by the UE (100) a first NAS message comprising an indicator indicating that the UE (200) supports of a secure channel for domain name system (DNS); receiving, from the network (200), by the UE (100) a second NAS message including DNS server security information in response to transmitting the first NAS message; and transmitting, to the network (200), by the UE (100) the DNS over the secure channel based on the DNS server security information.
