IPv6 in 3rd Generation Partnership Project (3GPP)

In particular, we exploit two functions of EMM messages described below. Issues for CT3 TR See Note 1 below. In passive attacks, Kune et al. Essentially, this indicates the following deployment options: Social identities are a compelling attack vector because mobile subscribers 3glp use mobile phones for accessing popular social networks and instant messaging applications. Under change control Type: We recommend that future standardization efforts take st into account.

As devices and applications are upgraded to support IPv6, they can start leveraging the IPv6 connectivity provided by the networks while maintaining the td to fall back to IPv4. The results are summarized below:.


We logged them using our passive attack setup. The PDN may be an operator-external public or private packet data network or an intra-operator packet data network.

Furthermore, even if individual app developers would fix their applications e. As shown in Fig. It shall not be deemed to have been filed until the opposition fee has been paid.

Practical Attacks Against Privacy and Availability in 4G/LTE Mobile Communication Systems

This enables the UE to detect a false network. CT 1 Secondary responsible groups: Network authentication for requests; ciphering for responses. T-Labs, Aalto University, and Huawei provided test devices used in our experiments.

A proof of concept paper by P. The adversary is assumed to be aware of social identities of subscribers.

Next, we discuss protection against DoS stemming from bidding down attacks D3. Each area has its own pool of gateways that are dedicated to a certain overlapping IPv4 address range also referred to as a zone. The results are summarized as follows: We now explain the importance of two RRC protocol messages and measurement information they carry. 3gp; this attack, the active attacker modifies messages exchanged between the eNodeB and UE.

How LTE Stuff Works?: November

In particular, we used the pdsch-ue application to scan a specified frequency and detect surrounding eNodeBs. The results are summarized below: General Versions Responsibility Related. Specification of a large system like LTE is a complex endeavor involving many trade-offs among conflicting requirements.


Thus, with the setting of the service type to “packet service via S1 for emergency bearer services”, both of the UE NAS layer and the core network i. We argue that similar protection for network capabilities is required due to the fact that the DoS attack has a persistent nature. We now demonstrate two methods in which the attacker exploits a specification and an implementation vulnerability to this end. The need for engineering the correct trade-offs between security and other requirements availability, performance, and functionality led to the vulnerabilities in the first place.

Furthermore, the design of the inter-operator roaming networks is such that the user-plane and transport-network IP addressing schemes are completely separated from each other.
