Lightweight KPABE Architecture Enabled in Mesh Networked Resource-Constrained IoT Devices

Abstract

Internet of Things (IoT) environments are widely employed in industrial applications including intelligent transportation systems, healthcare systems, and building energy management systems. For such environments of highly sensitive data, adapting scalable and flexible communication with efficient security is vital. Research investigated wireless Ad-hoc/mesh networking, while Attribute Based Encryption (ABE) schemes have been highly recommended for IoT. However, a combined implementation of both mesh networking and Key-Policy Attribute Based Encryption (KPABE) on resource-constrained devices has been rarely addressed. Hence, in this work, an integrated system that deploys a lightweight KPABE security built on wireless mesh networking is proposed. Implementation results show that the proposed system ensures flexibility and scalability of self-forming and cooperative mesh networking in addition to a fine-grained security access structure for IoT nodes. Moreover, the work introduces a case study of an enabled scenario at a school building for optimizing energy efficiency, in which the proposed integrated system architecture is deployed on IoT sensing and actuating devices. Therefore, the encryption attributes and access policy are well-defined, and can be adopted in relevant IoT applications.INDEX TERMS attribute based encryption, constrained-resources, cybersecurity, elliptic curves cryptography, internet of things, mesh networking This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.

Feistel Network Assisted Dynamic Keying based SPN Lightweight Encryption for IoT Security

“…Recalling the typical architecture of the IoT systems that encompasses Low-power Lossy (sensor) Networks (LLNs), gateways, transmission channel and data-warehouses or storage possessing undeniably security related vulnerabilities. Typically, the poorly interfaced nature of IoT devices and their inferior connection, especially operating online can undergo 377 | P a g e www.ijacsa.thesai.org security breaches and resulting losses [5][6][7]. On the other hand, attack probability gets increased manifolds over channel where different man-in-the middle attack (MITM), linear and differential attacks, impersonation, etc.…”

“…are more common. Similarly, once compromising the security access level of IoT devices due to poorly configured setup or keys, an intruder can manipulate the device and its functioning, thus obstructing overall performance [7]. However, looking into depth it can be found the key reason behind such attack possibility is poor encryption systems with limited keying capacity and inferior cipher-space [8].…”
