Tunis, Tunis, Tunisie Security Accent Temps plein
This project focuses on developing a lightweight policy -based access control (PBAC) framework for IoT and edge environments. The solution dynamically enforces security decisions using contextual factors such as device location, time, and battery level. It includes implementing a compact on -device policy engine capable of offline operation, a central policy management interface for authoring and distribution, and evaluation through real -world scenarios to measure latency, scalability, and reliability in constrained environments.
<\/div>

Problem Statement
<\/h4>

With the rapid growth of IoT and edge computing, billions of devices now operate autonomously and make sensitive decisions close to where data is generated. Traditional access control mechanisms, such as static RBAC or simple token validation, are insufficient in these distributed and context -dependent environments. IoT devices must enforce dynamic, context -aware authorization decisions based on real -time attributes like location, time, operational state, and device conditions — often while operating offline or under constrained resources.
<\/div>
The problem is to design and implement a lightweight, policy -based access control framework capable of evaluating such context -driven policies locally on IoT and edge devices while remaining manageable, auditable, and scalable from a central platform.
<\/div>

Methodology for Solution
<\/h4>

The project will follow a research and implementation -based approach. First, the student will conduct a comparative analysis of policy -based access control frameworks (e.g., OPA/Rego, Cedar, Oso) to identify a suitable engine for IoT environments. Next, a prototype system will be designed, consisting of a local policy enforcement agent on edge devices and a central policy management platform for authoring and distribution. Policies will be written, tested, and deployed to IoT devices for runtime evaluation based on contextual attributes. The solution will then be evaluated experimentally in simulated IoT scenarios to measure latency, scalability, and offline decision reliability.
<\/div>
