LASeR: Lightweight Authentication and Secured Routing for NDN IoT in Smart Cities

Abstract

Abstract-Recent literature suggests that the Internet of Things (IoT) scales much better in an Information-Centric Networking (ICN) model instead of the current host-centric Internet Protocol (IP) model. In particular, the Named Data Networking (NDN) project (one of the ICN architecture flavors) offers features exploitable by IoT applications, such as stateful forwarding, innetwork caching, and built-in assurance of data provenance. Though NDN-based IoT frameworks have been proposed, none have adequately and holistically addressed concerns related to secure onboarding and routing. Additionally, emerging IoT applications such as smart cities require high scalability and thus pose new challenges to NDN routing. Therefore, in this work, we propose and evaluate a novel, scalable framework for lightweight authentication and hierarchical routing in the NDN IoT (NDNoT). Our ns-3 based simulation analyses demonstrate that our framework is scalable and efficient. It supports deployment densities as high as 40,000 nodes/km 2 with an average onboarding convergence time of around 250 seconds and overhead of less than 20 KiB per node. This demonstrates its efficacy for emerging large-scale IoT applications such as smart cities.

Integrating PHY Security Into NDN-IoT Networks By Exploiting MEC: Authentication Efficiency, Robustness, and Accuracy Enhancement

“…It is assumed that EDs cannot afford the per-packet-level asymmetric encryption when preparing the packets due to their limited computation capacities; meanwhile, the MECD is assumed to be unconstrained. The private-public key pair and certificate generation and distribution are beyond the scope of our paper; interested readers can refer to [4], [6], [36].…”

“…In this regard, the authentication task of NDN has to tie to the content of every data packet directly rather than securing the E2E connection. Currently, NDN relies on the digital signature to protect the data provenance at the network layer, which, most of the time, requires the data producer (i.e., IoT end devices) to execute asymmetric cryptography at a packet granularity [4], [8]- [10]. The workload of the signing task can be intolerably high, especially for low-end sensorbased IoT devices [11], [12].…”

“…The studies of [24] and [25] integrated identitybased cryptography (IBC) and hierarchical IBC into NDN for authentication purposes. In a recent study [4], a symmetric key-based IoT device (standard node) authentication along with NDN routing was proposed for the smart city scenario. However, applying these methods in NDN-IoT could require additional encryptions to be carried out by the constrained IoT devices.…”

“…The MEC-enabled IoT can supplement the cloud computing-based IoT through harvesting the cache/storage ability, the idle computational capacity, and the context-aware resources located at the network edge [1]. NDN abilities of data content naming 1 and in-network caching can be beneficial to the IoT in terms of supporting device mobility [3] and raising the efficiency of data discovery and delivery [2] for the information-centric applications, such as intelligent transportation systems [4], [5] and building automation and management systems [6]. These IoT applications need to monitor and process big volumes of sensitive information collected from a large number of simple sensors.…”
