Title:
A METHOD FOR PREVENTING LEAKAGE OF AUTHENTICATION SEQUENCE NUMBER OF A MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/067627
Kind Code:
A1
Abstract:
This disclosure relates generally to registration and authentication processes between a wireless terminal and a core network and specifically to a protection of an authentication sequence number of the wireless terminal for leakage when being transmitted via a radio communication interface during the registration and authentication processes. Specifically, an increasing authentication sequence number is maintained by the wireless terminal and used in synchronization (under normal network operations) with another authentication sequence number maintained on the network side to track the registration and authentication activities of the terminal device and to help detect certain types of adversarial attacks (such as registration replays) on the wireless terminal via the radio communication interface. The authentication sequence number of the wireless terminal is synchronized with the network-side authentication sequence number by only transmitting the terminal-side sequence number to the network via a concealment mechanism similar to that of a permanent subscription identifier of the wireless terminal, to reduce its exposure to the radio interface, and by keeping track of and updating both sequence numbers on the terminal side and network side upon successful authentications or re-authentications.
