15:17 [Pub][ePrint] Commitments and Efficient Zero-Knowledge Proofs from Hard Learning Problems, by Abhishek Jain and Stephan Krenn and Krzysztof Pietrzak and Aris Tentes

  We construct a perfectly binding string commitment scheme whose security is based on the learning parity with noise ($\\LPN$) assumption, or equivalently, the hardness of decoding random linear codes. Our scheme not only allows for a simple and efficient zero-knowledge proof of knowledge for committed values (essentially a $\\Sigma$-protocol), but also for such proofs showing any kind of relation amongst committed values, i.e. proving that messages $\\vm_0,\\ldots,\\vm_u$, are such that $\\vm_0=C(\\vm_1,\\ldots,\\vm_u)$ for any circuit $C$.

To get soundness which is exponentially small in a security parameter $t$, and when the zero-knowledge property relies on the LPN problem with secrets of length $\\ell$, our $3$ round protocol has communication complexity $\\bigO(t|C|\\ell\\log(\\ell))$ and computational complexity of $\\bigO(t|C|\\ell)$ bit operations. The hidden constants are small, and the computation consists mostly of computing inner products of bit-vectors.

11:08 [Job][New] Ph.D. student, University of Trier, Germany


The PhD candidate will contribute to the research in the project “Implementation-Level Analysis of E-Voting Systems”, which is funded by the German Research Foundation (DFG) and is part of the DFG priority programme “Reliably Secure Software Systems - RS3”. The goal of this project is to develop general methods and techniques for the security analysis of Java systems that use cryptography, with e-voting systems being one of the motivating examples. The project combines techniques from program analysis/verification with techniques from cryptography and cryptographic protocol analysis.

We offer a creative international environment and the possibility to participate in internationally visible research. The salary scale for the position is TV-L E13 (100%). Subject to the final decision of the DFG, the position will be available from October 1st, 2012. Contracts are initially offered for two years, with the perspective of an extension by another two years.

The successful candidate should have a Master’s degree (or should be very close to completion thereof) in Computer Science, Mathematics, Information Security, or a related field, with a strong background in Theoretical Computer Science. Knowledge in program analysis/verification, logic, or cryptography is an asset. Good English skills are expected; knowledge of German is not required.

Applications should include:

  • Curriculum Vitae (including your contact address and work experience)
  • Cover letter explaining your motivation
  • Transcript of all courses and grades for your Bachelor and Master program
  • A short description of your Master’s work (max 1 page)
  • Contact details of (at least) one professor that can provide a recommendation for your application.

The deadline for applications is September 30th, 2012. However, late applications will be considered until the position is filled.

11:08 [Job][New] Assistant Professor, Kanazawa University, Japan

  Kanazawa University, Japan, invites applications for a tenure-track assistant professor position in advanced research area of information security, such as IT Security and Cryptography.

An appointee is expected on duty on December 1st, 2012 or at a possibly early time after that, and at latest by the end of March, 2013.

Research budget: Kanazawa University will provide funding support for the start-up of research: 10 million Yen for the first fiscal year and 5 million Yen for the second fiscal year.

11:08 [Job][New] Faculty position (Professur, W2) , Saarland University, Center for IT-Security, Privacy and Accountability

  We seek excellent applicants from all areas of IT-security, privacy and accountability, in particular in the areas of

• Privacy Enhancing Technologies;

• Language-based Security;

• Information Trust and Accountability;

• Network-, System- and Web-Security.

The position is part of the recently established IT-security center CISPA, which was established as part of an initiative by the German government to create three distinguished research centers in IT-security. CISPA covers a broad area of research problems in IT-security, privacy, and accountability, ranging from fundamental research questions to the development of new technologies and prototypic systems for practical application. The close connection of the CISPA to the department of computer science, the Max-Planck-Institute (MPI) for Informatics, the MPI for Software Systems, the German Research Center for Artificial Intelligence (DFKI), the Cluster of Excellence on Multimodal Computing and Interaction (MMCI), the Saarbrücken Graduate School of Computer Science and the Intel Visual Computing Institute (IVCI) is crucial for the success of the location. All of these institutes are in close proximity on the campus.

Aside from the standard requirements by public sector employment law, necessary qualifications for hiring include outstanding scientific skills, management skills and excellent teaching skills. The scientific qualification should encompass a doctoral degree as well as publications in the leading international IT-security conferences. The teaching and working language is English. Participation towards establishing the CISPA center and the acquisition of projects is expected.

The employment is tenured and initially a private-law employment relationship. A change to civil servant status is planned for the next year, as soon as the requirements by the budget and the civil service law are fulfilled.

11:08 [Job][New] PhD student, University of Luxembourg

  The University of Luxembourg seeks to hire an outstanding researcher for the Applied Security and Information Assurance group (APSIA, led by Prof. Peter Ryan) at its Interdisciplinary Centre for Security, Reliability and Trust (SnT). SnT is a recently formed centre carrying out interdisciplinary research in secure, reliable and trustworthy ICT systems and services, often in collaboration with industrial, governmental or international partners. The APSIA group is also associated with Laboratory of Algorithmics, Cryptology and Security (LACS) of the Computer Science and Communications Research Unit (CSC), which is part of the international and multidisciplinary Faculty of Science, Technology and Communication (FSTC) in University of Luxembourg.

The PhD topic is related to investigate efficient and secure mechanisms for individuals and organisations to outsource their data and related operations to third-party service providers. The research focus will mainly be on (but not limited to) cryptographic encryption schemes, which provide rigorous security properties yet allow authorized parties to directly search over the ciphertexts. The candidate is expected to design new schemes, analyse their security properties, and investigate the practical performances of the solutions.
