Privacy-Preserving File Sharing with Attribute Policies
Ciphertext-Policy Attribute-Based Encryption (CP-ABE) secure cloud file storage with dynamic revocation.
Project Overview
Files are client-side encrypted before uploading to untrusted cloud storage. Decryption keys are issued based on user attributes (e.g. Department=CSE, Role=Professor), ensuring fine-grained privacy control. ### Practical Student Engineering Solution Fully functional hardware demonstration prototype equipped with dedicated microcontrollers, precision sensors, actuators, and an interactive cloud/mobile telemetry dashboard. ### Key Learning Outcomes - Embedded C / MicroPython firmware architecture and sensor interfacing - IoT telemetry protocols (MQTT / HTTP / BLE / LoRaWAN) - Power regulation, hardware debugging, and PCB design principles - Comprehensive technical documentation aligned with IEEE academic standards
Modern commercial and industrial infrastructure requires automated, real-time sensing and telemetry. Conventional manual monitoring suffers from high latency, human error, and lack of predictive fault visibility for Privacy-Preserving File Sharing with Attribute Policies.
A turnkey engineering prototype integrating high-precision sensor modules, dedicated microcontroller unit, and cloud telemetry protocols to automate measurement, trigger alert thresholds, and provide remote dashboard control.
