eHAPAC: A Privacy-Supported Access Control Model for IP-Enabled Wireless Sensor Networks

Abstract

The implementation of IP technology in wireless sensor networks has promoted the development of many smart scenarios. To enhance secure access in IP-enabled wireless sensor networks, access control to sensor nodes is a necessary process. However, access control currently faces two challenges, feasibility and preservation of user access privacy. In this paper, we propose eHAPAC, a novel privacy-preserving access control model for IP-enabled wireless sensor networks. The contributions of our paper include three parts. First, this paper integrates the Hidra access control protocol and APAC privacy-preserving model, addressing the issue of privacy-preserving access control in resource-constrained devices. Second, this paper proposes an enhanced Hidra protocol to implement the unlinkability of protocol message exchanges. Third, to solve the problem of third party credibility, this paper improves the group signature-based APAC model and utilizes blockchain technology to manage the storage and publication of public group signature keys. Security analysis and performance evaluation prove that our protocol is secure and effective.

Evaluation of Correlation between Temperature of IoT Microcontroller Devices and Blockchain Energy Consumption in Wireless Sensor Networks

“…A test bed was used to collect experimental power consumption and device temperature data. We have used statistical software tools to evaluate the power consumption and temperature data that we have collected from our test bed [ 20 ]. To evaluate performance and measure the energy usage and device temperature of networked devices running different blockchain algorithms, we deployed a physical IoT sensor network using low-powered devices.…”

Security and Privacy in Wireless Sensor Networks: Advances and Challenges

“…Reference [9] presents a model for the problem of privacy-preserving access control in IP-enabled WSNs, namely eHAPAC. They integrated Hidra access control and an APAC model to ensure privacy and unlinkability in resource-constrained devices and improved the group signature-based APAC model to prevent arbitration organizations from cheating.…”
