ABSTRACT

We present TEEshift, a tool suite that protects the confiden- tiality and integrity of code by shifting selected functions into TEEs. Our approach works entirely on binary-level and does not require the adaption of source code projects or build environments, nor does it require compiler-level patches. Programmers provide a list of ELF symbols pointing to the functions that should be protected. After post-processing an ELF binary with TEEshift, the selected functions are not present in cleartext anymore. Only after attesting to a re- mote party that the loading enclave behaves with integrity, the functions are decrypted, but remain inside the enclave protected against reverse engineering. An online connection is only required when a program starts for the first time on a PC. Afterwards, sealing is used to securely store the decryption key and bind it to the PC. By allowing program- mers to move selected function into TEEs, without patching their source code, we provide a convenient way to enable TEEs in existing projects while preserving the flexibility for a finegrained security and performance tradeoff. We evaluated our tool using a real world gaming application, confirming the practicability of our approach for existing projects. We overcome the limitation of the fragmented TEE landscape by building on top of Asylo, an open framework by Google for apps which aim to support different TEEs such as Intel SGX and AMD SEV using a unified API.

ABSTRACT

Die digitalen Schlüsseltechnologien „Künstliche Intelligenz“ (KI) und „Blockchain“ sind derzeit in aller Munde. Spannend wird es aber, wenn diese beiden Felder zusammenwachsen. Daraus ergeben sich insbesondere für das Internet der Dinge interessante Perspektiven. Sind wir auf dem Weg zu einer weiteren industriellen Revolution – der Industrie 5.0?

ABSTRACT

In this paper we introduce the design and technical implementation of the citizen science project Migraine Radar. The goal of the project is to establish a large collection of migraine attack data in order to explore the trigger factors of migraine attacks. A main focus is the investigation of the influence of environmental factors like weather or changes in the geomagnetic activity on the frequency of migraine attacks. After registering with the project, participants report their migraine attack data using a web app or one of the smartphone apps implemented for Android and iOS. As a benefit, the system serves as a personal headache calendar and participants have access to statistics and individualized reports about their attacks. For scientific analysis the data are pre-processed and provided to the researchers in an anonymized way.
