Solutions for distributed denial of service (ddos) attack remediation in a non-terrestrial network (ntn

Abstract

Disclosed herein are solutions to remediate a distributed denial of service attack. In an example, a wireless transmit and receive unit (WTRU) transmits, to a network, a first attach request message including an store and forward (S&F) mode parameter. The WTRU receives, from the network, information indicating a puzzle and one or more parameters of the puzzle. Further, the WTRU generates evidence based on solving the puzzle. Moreover, the WTRU transmits, to the network, a second attach request message including the evidence. In an example, the WTRU receives, from the network, an attach reject message responsive to the S&F mode parameter. Additionally or alternatively, the WTRU receives, from the network, the S&F mode parameter. Additionally or alternatively, the network is a non-terrestrial network (NTN). Additionally or alternatively, the network includes a satellite. Additionally or alternatively, the includes a mobility management entity (MME) non-terrestrial (NT).
