TrustLite: a security architecture for tiny embedded devices
Patrick Koeberl,Steffen Schulz,Ahmad-Reza Sadeghi,Vijay Varadharajan +3 more
- 14 Apr 2014
TL;DR: This work describes mechanisms for secure exception handling and communication between protected modules, enabling seamless interoperability with untrusted operating systems and tasks, and presents the TrustLite security architecture for flexible, hardware-enforced isolation of software modules.
Hide and seek in time: robust covert timing channels
Yali Liu,Dipak Ghosal,Frederik Armknecht,Ahmad-Reza Sadeghi,Steffen Schulz,Stefan Katzenbeisser +5 more
- 21 Sep 2009
TL;DR: The experimental results show that the novel covert timing channel introduced in this paper can achieve strong robustness and undetectability, by varying the data transmission rate.

Robust and undetectable steganographic timing channels for i.i.d. traffic
Yali Liu,Dipak Ghosal,Frederik Armknecht,Ahmad-Reza Sadeghi,Steffen Schulz,Stefan Katzenbeisser +5 more
- 28 Jun 2010
TL;DR: A steganographic timing channel that is both robust and provably undetectable for network traffic with independent and identically distributed (i.i.d.) inter-packet delays is introduced and verified by conducting a series of experiments on Telnet traffic.
Trusted virtual domains – design, implementation and lessons learned
Luigi Catuogno,Alexandra Dmitrienko,Konrad Eriksson,Dirk Kuhlmann,Gianluca Ramunno,Ahmad-Reza Sadeghi,Steffen Schulz,Matthias Schunter,Marcel Winandy,Jing Zhan +9 more
- 17 Dec 2009
TL;DR: The need for and the realization of intra-TVD access control, a hypervisor abstraction layer for simplified TVD management, necessary components of a TVD policy and revocation issues, and the prototype implementation for the Xen and L4 microkernel platforms are discussed.
