A security‐driven network architecture for routing in industrial Internet of Things

Abstract

Industrial Internet of Things (IIoT), as the integration of industrial network and IoT, has attracted a lot of attention from both academia and industry. However, with such integration deepens, many issues suffered by the industrial networks are exposed and magnified. The secure routing is a key focus, since the industrial environment is extremely vulnerable and many potential threats (eg, distributed denial of service and selfish attacks) are introduced due to the connection to the Internet. In order to prevent the threats from the Internet and embrace the benefits of IIoT, a security‐driven network framework for routing is particularly designed. Specifically, we first leverage the technologies of software‐defined networking (SDN), network function virtualization (NFV), and blockchain to create the overall framework which is flexible, programmable, and secure. On one hand, the three‐level structure of SDN/NFV is applied to each domain, based on which we can flexibly control and program the underlying forwarding devices in this domain for the purpose of calculating the optimal routing policies. On the other hand, the blockchain is applied among different SDN controllers to create a trust and untamperable environment. Then, under this framework, a secure routing mechanism is proposed as well to prevent the attacks on the basis of node identity authentication and node behavior authentication. The simulation experiments are carried out on the OMNet++ platform and the experimental results indicate that the proposed mechanism outperforms the other state‐of‐the‐art methods in terms of scalability and robustness especially when encountering malicious attacks.

Fault-Tolerant Secure Routing of B H n -Based Data Center Networks

“…if the SBH(s, d) is contained in a maximal safe subgraph msg; then (3) e message is sent by the minimum feasible path from s to d; (4) else (5) Select a neighbor s′ along with a minimum feasible path from s to d where SBH(s′, d) is contained in a maximal safe subgraph msg, pass the message to s′, and pass the message; (6) end if (7) end for (8) return message-pass(s, d, msg); ALGORITHM 1: Fault-tolerant routing with local safety level.…”

“…As crucial components of IoT, sensor networks include connected sensors and associated devices, which deploy plenty of heterogeneous sensing nodes for capturing environmental data [2][3][4]. e secure routing is a key focus since the industrial environment is extremely vulnerable and many potential threats (e.g., distributed denial of service and selfish attacks) are introduced due to the connection to the Internet [5]. Load balancing is a highend solution for large-scale networks to solve high-load access and a large number of concurrent requests.…”

Proof-of-Improved-Participation: A New Consensus Protocol for Blockchain Technology

“…Here is how the methods of implementing these structures work. The existing mini-net simulator [21] analyzes existing problems and guides the data needed to implement the IoT system. The Pyethereum Test Tool [22] is also used to further improve and validate the functionality of the blockchain system designed here.…”

Trust Aware Multi-Objective Metaheuristic Optimization Based Secure Route Planning Technique for Cluster Based IIoT Environment

“…In [11], a three-level infrastructure of software defined network (SDN) or Network function visualization (NFV) was executed for all domains dependent upon that it is flexibly controlled and programs the basic forwarding device under this domain with the aim of computing an optimum routing policy. Conversely, the blockchain was implemented amongst distinct SDN controllers for creating trust and untamperable environments.…”
