Research areas

My research sits at the intersection of security and real-world systems: protecting the data that cloud platforms and IoT devices collect, store and share.

Access control & dynamic authorization

Deciding who may access what, and revoking that access safely when circumstances change. My work covers attribute-based, trust-based and behavior-based access control models, adaptive XACML policies, and token- and key-revocation schemes for multi-authority cloud storage.

Cloud & IoT security and privacy

Protecting data that is generated by IoT devices and outsourced to the cloud: privacy-preserving and real-time schemes, private information retrieval, secure retrieval of sliced multimedia data, leakage-resilient outsourcing and remotely controllable data self-destruction.

Blockchain & applied cryptography

Using blockchains and cryptographic primitives to give users control over their data — from consortium-blockchain confirmation mechanisms and self-sovereign personal data stores to blockchain-based key revocation for open banking.

Smart systems for sustainability & health

Building secure IoT platforms that solve real problems in Saudi Arabia and beyond: precision greenhouse cultivation, smart subsurface irrigation for date palms, cold-storage monitoring, energy optimization, and home-care monitoring of chronic diseases using deep learning.
