Using Trusted Execution Environments for Secure Stream Processing of Medical Data

Abstract: Processing sensitive data, such as those produced by body sensors, on third-party untrusted clouds is particularly challenging without compromising the privacy of the users generating it. Typically, these sensors generate large quantities of continuous data in a streaming fashion. Such vast amount of data must be processed efficiently and securely, even under strong adversarial models. The recent introduction in the mass-market of consumer-grade processors with Trusted Execution Environments (TEEs), such as In… Show more

“…Some papers propose data leak protection, by screening data and comparing fingerprints [24]- [30]. Segarra et al [31] propose an architecture to securely stream medical data using Trusted Execution Environments, while Zuo et al investigate data leakage in mobile applications interaction with the cloud [32].…”

“…Comparing our platform with the existing state-of-the-art systems, SafeSpark differs from the hardware-based approaches [31,32,35] since it enables the use of deterministic schemes to compute equality and order operations. This functionality makes it possible to achieve better performance results while relaxing the security guarantees.…”

“…Segarra et al in [32] propose a secure processing system build on top of Spark Streaming that uses Intel SGX to compute stream analytics over public untrusted clouds. This solution offers security guarantees similar to those proposed in Opaque without requiring changes to applications code.…”

“…CaSE [44] is a cache-assisted secure execution framework for the TRUSTZONE to defend against multiple attacks. Others [28,36,41] have implemented frameworks for TEEs to securely process data streams that could benefit from KEVLAR-TZ. However, while such projects have implemented full-fledged frameworks, KEVLAR-TZ provides a lean and resource-efficient cache with an easy-to-use API for applications that need fast access to persistent data.…”
