I developed a TrustZone-based project using Genode and the i.MX53 QSB. I have been accepted to the Workshop on Mobile and Cloud Security and Privacy (WMCSP) 2016 which is hosted in collaboration with the Symposium on Reliable Distributed Systems (SRDS).

I'll leave the title and abstract of my work here.

Title: ARM TrustZone for Secure Image Processing on the Cloud

Abstract: Nowadays, offloading storage and processing capacity to cloud servers is a growing trend. This happens because high storage capacity and powerful processors are expensive, whilst cloud services provide a cheaper, ongoing, and reliable solution. The problem with cloud-based solutions is that servers are highly accessible through the Internet and therefore considerably exposed to hackers and malware. In this paper, we design and implement Darkroom, a secure image processing service for the cloud leveraging ARM TrustZone technology. Our system enables users to securely process image data in a secure environment that prevents exposure of sensitive data to the operating system. We evaluate our system and observe that our solution adds a small overhead to image processing when compared to computer platforms that require the entire operating system to be trusted.

I'm going to present this project in Budapest at the Symposium 25th of September 2016 and I though you might be interested in knowing more about the project.
