Realizing connected car technology (vehicular networks) with 5G seems promising, taking into account the bandwidth-hungry and delay-sensitive applications. But, the security of VANET applications is also very important. What security issues (specific to 5G) do the research community need to address before depolying 5G-based vehicular networks?
Here are some that I understand, are very important.
a. 5G focuses on lower layer security (using the physical properties of the channel) whereas existing VANET standards focus on upper layer security (using cryptographic techniques).
b. Identity management
c. Larger attack surface because of the SDN, NFV, MIMO, etc.
d. User privacy, and so on.
Is there something that I am missing?
If there are any standards/existing work in this direction that I am unaware of, please let me know. Thank you in advance for participating in the discussion.
I suggest you read our paper:
Preprint A Low Overhead Cooperative-based Authentication Protocol for VANETs
Vahid Ranjbar Thank you for sharing your paper. I skimmed through the paper, but I do not see how this paper is related to the current discussion.
Dear Rasheed Hussain,
I limit myself here only to the 5G security. Because 5G Mobile Networks (5GMNs) are integrated with the IoT and the network technologies SDN and NFV are used in 5GMNs, vulnerabilities and threats in IoT, SDN, and NFV must be considered in the 5G security analysis. The formation of virtual private 5G networks with SDN and NFV creates new security vulnerabilities and threats. Consequently, 5G Security is a very important and very complex topic.
Thus, the 5G security analysis must be performed globally and systematically to capture as many security vulnerabilities and threats as possible. In this context I would like to refer - to:
- 3GPP 5G Security – A well-founded introduction
http://www.3gpp.org/news-events/3gpp-news/1975-sec_5g
- 3GPP TS 33.501: “Security architecture and procedures for 5G system”; V15.2.0 (2018-09)
https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=3169
The TS 33.501 (see: Page 19, Fig, 4-1: Overview of the security architecture) defines 5 security dimensions
(areas) and each dimension has specific security objectives. These security dimensions are:
- I. Network access security: the set of security features that enable a user equipment to authenticate and access services via the network securely and in particularly, to protect against attacks on the (radio) interfaces.
- II. Network domain security: the set of security features that enable network nodes to securely exchange signalling data and user plane data.
- III. User domain security: the set of security features that secure the user access to mobile equipment.
- IV. Application domain security: the set of security features that enable applications in the user domain and in the provider domain to exchange messages securely.
- V. SBA (Service-Based Architecture) domain security: the set of security features that enables network functions of the SBA architecture to securely communicate within the serving network domain and with other network domains.
- VI. Visibility and configurability of security: the set of features that enable the user to be informed whether a security feature is in operation or not.
In order to analyze the 5G Security on the basis of TS 33.501, a good support can be found in the following ITU-T document:
- ITU-T X.805: Security architecture for systems providing end-to-end communications; 10/2003
https://www.itu.int/rec/T-REC-X.805-200310-I/en
ITU-T X.805 contains: security architecture, security dimensions (access control, authentication, non-repudiation, data confidentiality, communication security, data integrity, privacy), analysis of security vulnerabilities, …
I recommend these two very good articles:
- Ijaz Ahmad, Tanesh Kumary, Madhusanka Liyanage, Jude Okwuibe, Mika Ylianttila, Andrei Gurtov: “5G Security: Analysis of Threats and Solutions“; 2017 IEEE Conference on Standards for Communications and Networking (CSCN), Sept 2017; DOI: 10.1109/CSCN.2017.8088621
- Ijaz Ahmad, Tanesh Kumar, Madhusanka Liyanage, Jude Okwuibe, Mika Ylianttila, Andrei Gurtov: Overview of 5G Security Challenges and Solutions; IEEE Communications Standards Magazine, Vol. 2(1) , March 2018; DOI: 10.1109/MCOMSTD.2018.1700063
Finally, I would like to recommend these sources of information about 5G security:

Article Cell-Less Communications in 5G Vehicular Networks Based on V...
https://www.springer.com/la/book/9783030021757
Vehicular communications, though a reality, must continue to evolve to support higher throughput and, above all, ultralow latency to accommodate new use cases, such as the fully autonomous vehicle. Cybersecurity must be assured since the risk of losing control of vehicles if a country were to come under attack is a matter of national security. This article presents the technological enablers that ensure security requirements are met. Under the umbrella of a dedicated network slice, this article proposes the use of content-centric networking (CCN), instead of conventional transmission control protocol/Internet protocol (TCP/IP) routing and permissioned blockchains that allow for the dynamic control of the source reliability, and the integrity and validity of the information exchanged.
