The specification vulnerabilities responsible for DoS attacks based on TAU procedure D1 and D2 can be fixed without changes in the protocol itself. The user-plane traffic bypasses the MME. There are two solutions to avoid UEs being tracked. Further embodiments of the invention are claimed in the dependent claims.

Therefore, cellular device and gateway implementations from different vendors may have varying support for this functionality. We followed standard responsible disclosure practices of all affected manufacturers. Paging refers to the process used when MME needs to locate a UE in a particular area and deliver a network service, such as incoming calls.

IPv6 in 3rd Generation Partnership Project (3GPP)

There is no single approach for transition to IPv6 that can meet the needs for all deployments and models. Network operators are not able to offer services since subscribers are unavailable technically and no billing would occur. It can indicate the following features whether supported or not: Impact of these attacks are as follows: However, our findings may have changed ta equilibrium in this trade-off. However, currently it lacks stability.


However, in the above cases the safety margins turn out to be too narrow. Prefix Delegation IPv6 prefix delegation is a part of Release and is not covered by any earlier releases. The objective of the semi-passive attack is to determine the presence of a subscriber in a TA and further, to find the cell g3pp which the subscriber is physically located in. For attacks in real LTE networks, we took care not to interrupt normal service to other UEs in the testing zone.

By downgrading subscribers, an attacker could attempt to launch known 2G or 3G attacks, besides loss of LTE services. Authentication and Key Agreement. This document is not an Internet Standards 3gop specification; it is published for informational purposes. However, depending on the alert notification capabilities provided 3gp; application layer of various mobile operating systems installed on the UE, the subscriber could be notified of limited services or no network connectivity status.

Mobility Management Entity The Mobility Management Entity MME is a network element that is responsible for control-plane functionalities, including authentication, authorization, bearer management, layer-2 mobility, etc.


ESM message container

Veranlassen S einer Extended Service Request message bzw. Action date Action Author. Other types of configurations are not standardized. In this attack, two rogue eNodeBs are operated in the same cell where the subscriber is present. Later, the attacker opens his active chat window corresponding to the recipient and composes a message but does not send.

We noticed that there is no standard approach across different mobile operating systems to indicate the type of active network mode e.

We argue that similar protection for network capabilities is required due to the fact that the DoS attack has a persistent nature. The user eventually accesses services in one or more PDNs. We then characterize preliminary measurements used for realizing the attacks and new techniques for triggering subscriber paging. Hence, all of the UEs assigned to a single gateway can be assigned private IPv4 addresses.

The dual- stack 3gp connection, i. We logged them using our passive attack setup. The following are some operational aspects to consider for running a network with IPv6-only bearers:.
