To be considered for this studentship, candidates must therefore be prepared to undergo GCHQ\\\'s security clearance procedures.

The two studentships will be in the following areas:

Title: Authentication, Ciphers, and Encryption

Supervisors: Dan Page and Martijn Stam

Title: Information Leakage aware Verification

Supervisors: Elisabeth Oswald and Kerstin Eder

09:55 [Job][New] PhD , University of Luxembourg

  The University of Luxembourg seeks to hire an outstanding researcher for the Applied Security and Information Assurance (APSIA) group 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.

REF : F1-070079

Fixed-term contract 3 years, full-time (40 hrs/week)

Number of Positions : 1

Your Role

The PhD topic is to design and analyse lattice-based cryptosystems. The research focus will mainly be on (but not limited to) investigating lattice-related hardness assumptions, both in terms of classical and quantum models of computation, and then designing novel, practical lattice-based public-key cryptosystems. Other classes of “hard” problems, for example based on coding theory and braid groups, will also be investigated.

The student will work closely with Prof. Peter Y. A. Ryan and Dr. Qiang Tang. Moreover, the student will be encouraged to work with other members in the APSIA group and collaborate with researchers from other related research units, such as LACS.



09:55 [Job][New] Ph.D. student, DFG Research Training Group UbiCrypt, Horst Görtz Institute for IT-Security, Ruhr-University Bochum, Germany

 

The Horst Görtz Institute for IT-Security (HGI) at Ruhr-University Bochum is one of Europe’s leading research centers in IT security. The DFG, or German Research Foundation, awarded more than €4 million to the HGI for the establishment of the interdisciplinary research training group “New Challenges for Cryptography in Ubiquitous Computing”. We are looking for candidates with outstanding Master/Diplom in the fields of computer science, electrical engineering, mathematics or related areas.

The research training group will study problems which are fundamental for securing the Internet of Things. The research is structured in three levels: cryptographic primitives, device and system level. The research topics range from cryptographic foundations such as fully homomorphic encryption for privacy in cloud computing, over security for medical implants to internet security solutions involving new national ID cards. A central goal of the doctoral training is an interdisciplinary and structured education at the highest scientific level. Establishing networks to top internationally research groups is part of the training.

A group of internationally renowned researchers together with excellent funding provides an extremely interesting scientific environment. The HGI is known for its good working atmosphere.

The Ruhr-University Bochum supports women‘s career development. Applications from women are thus explicitly welcome. In those areas in which women are underrepresented they will be considered preferentially according to the regulations of the „Landesgleichstellungsgesetz” if their abilities, aptitude and professional performance are equal with those of the fellow applicants unless reasons concerning the person of a fellow applicant are predominant.

In case of equal qualification, applications of severely disabled persons or persons that are regarded as being on a par with severely disable

19:17 [Pub][ePrint] Message-Locked Encryption and Secure Deduplication, by Mihir Bellare and Sriram Keelveedhi and Thomas Ristenpart

  We formalize a new cryptographic primitive, Message-Locked Encryption (MLE), where the key under which encryption and decryption are performed is itself derived from the message. MLE provides a way to achieve secure deduplication (space-efficient secure outsourced storage), a goal currently targeted by numerous cloud-storage providers. We provide definitions both for privacy and for a form of integrity that we call tag consistency. Based on this foundation, we make both practical and theoretical contributions. On the practical side, we provide ROM security analyses of a natural family of MLE schemes that includes deployed schemes. On the theoretical side the challenge is standard model solutions, and we make connections with deterministic encryption, hash functions secure on correlated inputs and the sample-then-extract paradigm to deliver schemes under different assumptions and for different classes of message sources. Our work shows that MLE is a primitive of both practical and theoretical interest.



19:17 [Pub][ePrint] Pairings on Generalized Huff Curves, by Abdoul Aziz Ciss and Djiby Sow

  This paper presents the Tate pairing computation on generalized Huff curves proposed by Wu and Feng in \\cite{Wu}. In fact, we extend the results of the Tate pairing computation on the standard Huff elliptic curves done previously by Joye, Tibouchi and Vergnaud in \\cite{Joux}. We show that the addition step of the Miller loop can be performed in $1\\mathbf{M}+(k+15)\\mathbf{m}+2\\mathbf{c}$ and the doubling one in $1\\mathbf{M} + 1\\mathbf{S} + (k + 12) \\mathbf{m} + 5\\mathbf{s} + 2\\mathbf{c}$ on the generalized Huff curve.



19:17 [Pub][ePrint] New Preimage Attack on MDC-4, by Deukjo Hong and Daesung Kwon

  In this paper, we provide some cryptanalytic results for

double-block-length (DBL) hash modes of block ciphers, MDC-4. Our

preimage attacks follow the framework of Knudsen et al.\'s

time/memory trade-off preimage attack on MDC-2. We find how to apply

it to our objects. When the block length of the underlying block

cipher is $n$ bits, the most efficient preimage attack on MDC-4

requires time and space about $2^{3n/2}$, which is to be compared to

the previous best known preimage attack having time complexity of

$2^{7n/4}$. Additionally, we propose an enhanced version of MDC-4,

MDC-4$^*$ based on a simple idea. It is secure against our preimage

attack and previous attacks and has the same efficiency as MDC-4.
