Short CV

Ahmad-Reza Sadeghi is a full Professor of Computer Science at the Technische Universität Darmstadt, in Germany, where he heads the System Security Lab.  Since January 2012 he is also the Director of Intel Collaborative Research Institute for Secure Computing (ICRI-SC) at TU Darmstadt. He is a member of the profile area CYSEC of TU Darmstadt.

He received his PhD in Computer Science with the focus on privacy protecting cryptographic protocols and systems from the University of Saarland in Saarbrücken, Germany. Prior to academia, he worked in Research and Development of Telecommunications enterprises, amongst others Ericson Telecommunications.  He has been leading and involved in a variety of national and international research and development projects on design and implementation of Trustworthy Computing Platforms and Trusted Computing, Security Hardware, and Applied Cryptography. He has been serving as general or program chair as well as program committee member of major conferences and workshops in Information Security and Privacy. He is Editor-In-Chief of IEEE Security and Privacy Magazine, and on the editorial board of ACM Books. He served 5 years on the editorial board of the ACM Transactions on Information and System Security (TISSEC), and was guest editor of the IEEE Transactions on Computer-Aided Design (Special Issue on Hardware Security and Trust).

Prof. Sadeghi has been awarded with the renowned German prize “Karl Heinz Beckurts” for his research on Trusted and Trustworthy Computing technology and its transfer to industrial practice. The award honors excellent scientific achievements with high impact on industrial innovations in Germany. Further, his group received German IT Security Competition Award 2010.

Abstract Until recently, it was widely believed that code randomization (such as fine-grained ASLR) can effectively mitigate code reuse attacks. However, a recent attack strategy, dubbed just-in-time return oriented programming (JIT-ROP), circumvents code randomization by disclosing the (randomized) content of many memory pages at runtime. In order to remedy this situation, new and improved code randomization defenses have been proposed. The contribution of this paper is twofold: first, we conduct a security analysis of a recently proposed fine-grained ASLR scheme that aims at mitigating JIT-ROP based on hiding direct code references in branch instructions. In particular, we demonstrate its weaknesses by constructing a novel JIT-ROP attack that is solely based on exploiting code references residing on the stack and heap. Our attack stresses that designing code randomization schemes resilient to memory disclosure is highly challenging. Second, we present a new and hybrid defense approach, dubbed Isomeron, that combines code randomization with execution-path randomization to mitigate conventional ROP and JIT-ROP attacks. Our reference implementation of Isomeron neither requires source code nor a static analysis phase. We evaluated its efficiency based on SPEC benchmarks and discuss its effectiveness against various kinds of code reuse attacks.
