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 Secure outsourcing of computation to an untrusted (cloud) service provider is becoming more and more important. Pure cryptographic solutions based on fully homomorphic and verifiable encryption, recently proposed, are promising but suffer from very high latency. Other proposals perform the whole computation on tamper-proof hardware and usually suffer from the the same problem. Trusted computing (TC) is another promising approach that uses trusted software and hardware components on computing platforms to provide useful mechanisms such as attestation allowing the data owner to verify the integrity of the cloud and its computation. However, on the one hand these solutions require trust in hardware (CPU, trusted computing modules) that are under the physical control of the cloud provider, and on the other hand they still have to face the challenge of run-time attestation. In this paper we focus on applications where the latency of the computation should be minimized, i.e., the time from submitting the query until receiving the outcome of the computation should be as small as possible. To achieve this we show how to combine a trusted hardware token (e.g., a cryptographic coprocessor or provided by the customer) with Secure Function Evaluation (SFE) to compute arbitrary functions on secret (encrypted) data where the computation leaks no information and is verifiable. The token is used in the setup phase only whereas in the time-critical online phase the cloud computes the encrypted function on encrypted data using symmetric encryption primitives only and without any interaction with other entities.
