Welcome to my academic website! My name is Christian Priebe and I was a PhD student in the Large-Scale Data & Systems Research Group at Imperial College London under the supervision of Prof. Peter Pietzuch. My PhD is supported by a CDT High Performance Embedded And Distributed Systems (HiPEDS) scholarship. I finished my PhD in 2020 and am now working in industry. I am specifically interested in Systems and Systems Security research including the topics of Cloud Computing Security, Trusted Computing and Secure (Remote) Data Processing.


CloudSafetyNet: Data-centric Security for Clouds

  • Lightweight data leakage detection in multi-tenant clouds through client-side tagging, server-side socket level monitoring and inter-tenant collaboration.
  • Prevention of data disclosure vulnerabilities in web applications based on user-defined data flow policies and proxy-based policy enforcement.

SERECA: Secure Enclaves for Reactive Cloud Application & SecureCloud: Secure Big Data Processing in Untrusted Clouds

  • Automated partitioning of legacy applications for the execution on trusted hardware.
  • Providing system support for the execution of unmodified binaries in SGX enclaves.

SGX-LKL: Library OS for Running Unmodified Binaries in Intel SGX Enclaves

SGX-LKL is a library OS designed to run unmodified Linux binaries inside SGX enclaves. It uses the Linux Kernel Library (LKL) and a modified version of musl as C standard library implementation. The goal of SGX-LKL is to provide system support for complex applications and managed runtimes such as the JVM with minimal or no modifications and minimal reliance on the host OS.
