Secure and Blockchain-Based Emergency Driven Message Protocol for 5G Enabled Vehicular Edge Computing

Abstract

Basic safety message (BSM) are messages that contain core elements of a vehicle such as vehicle’s size, position, speed, acceleration and others. BSM are lightweight messages that can be regularly broadcast by the vehicles to enable a variety of applications. On the other hand, event-driven message (EDM) are messages generated at the time of occurrence such as accidents or roads sliding and can contain much more heavy elements including pictures, audio or videos. Security, architecture and communication solutions for BSM use cases have been largely documented on in the literature contrary to EDM due to several concerns such as the variant size of EDM, the appropriate architecture along with latency, privacy and security. In this paper, we propose a secure and blockchain based EDM protocol for 5G enabled vehicular edge computing. To offer scalability and latency for the proposed scenario, we adopt a 5G cellular architecture due to its projected features compared to 4G tong-term evaluation (LTE) for vehicular communications. We consider edge computing to provide local processing of EDM that can improve the response time of public agencies (ambulances or rescue teams) that may intervene to the scene. We make use of lightweight multi-receiver signcryption scheme without pairing that offers low time consuming operations, security, privacy and access control. EDM records need to be kept into a distributed system which can guarantee reliability and auditability of EDM. To achieve this, we construct a private blockchain based on the edge nodes to store EDM records. The performance analysis of the proposed protocol confirms its efficiency.

Privacy-preserving contact tracing in 5G-integrated and blockchain-based medical applications

“…Both the blockchain and 5G can be considered as the next-generations technology, hence their integration also attracts the attention of researchers, which covers a variety of scenarios including Internet-of-Things (IoT) [4] , [17] , [41] , and edge computing [15] , [19] , [28] .…”

“…In the edge computing scenario, Nkenyereye et al. [28] adopted a 5G cellular architecture of Emergency Driven Message (EDM) Protocol which provides higher scalability with lower latency. They also constructed a blockchain-based system where each node is seen as an edge node to reliably store EDM records of which the privacy is protected by a lightweight signcryption scheme.…”

“…Further, by using Scyther simulation, it is found by protocol run that the information is protected and also better in terms of communication and computational overheads w.r.t., the existing works. Nkenyereye et al [24] adopted 5G cellular architecture to provide scalability, latency and other features in comparison to 4G Long-Term Evaluation (LTE) for vehicular communications. To enhance the response time of Event Driven Messages (EDM) an edge computing architecture is considered to deliver local processing.…”

Revealing Development Trends in Blockchain-Based 5G Network Technologies through Patent Analysis

“…South Korea's Sungkyunkwan University has proposed a real-time atmospheric pollution index measurement platform based on 5G wireless networks and blockchain [25]. Also in South Korea, a team at Sejong University has designed a 5G-based edge vehicle computing model and a blockchain-based secure event-driven message (EDM) protocol to provide EDM auditability [26]. Singapore's Nanyang Technological University uses 5G networks to enable vehicles, sensors, and other countless devices to interact and share data on cellular networks, overcoming LTE shortcomings through the blockchain, and resolving handover security problems [27].…”
