Root Optimization of Polynomials in the Number Field Sieve, by Shi Bai and Richard P. Brent and Emmanuel Thom\\\'e
The general number field sieve (GNFS) is the most efficient
algorithm known for factoring large integers. It consists of several
stages, the first one being polynomial selection. The quality of the
chosen polynomials in polynomial selection can be modelled in terms of
size and root properties. In this paper, we describe some algorithms for
selecting polynomials with very good root properties.
Integrated PKE and PEKS - Stronger Security Notions and New Constructions , by Yu Chen and Jiang Zhang and Zhenfeng Zhang and Dongdai Lin
In this paper we investigate the security for integrated public-key encryption (PKE)
and public-key encryption with keyword search (PEKS) schemes. We observe that the security
notions for integrated PKE and PEKS schemes considered in the existing literature are not strong
enough to capture practical attacks, thus define a new notion named joint CCA-security which is
shown to be stronger than the previous ones. We also propose two simple and efficient constructions
of jointly CCA-secure integrated PKE and PEKS schemes from anonymous (hierarchical) identity-
based encryption schemes. Besides, we review the consistency for PEKS schemes and improve
Postdoctoral Research Fellow, Queensland University of Technology, Brisbane, Australia
The Information Security discipline at the Queensland University of Technology (QUT) in Brisbane, Australia, invites applications for a 2-year post-doctoral researcher position in cryptography starting in 2013. The focus of the position is on analyzing and characterizing the overall security of real-world cryptographic protocols such as TLS. We are looking for outstanding candidates with experience in cryptographic modelling, provable security, and key exchange protocols. The position is supported by an Australia Research Council (ARC) Discovery Project grant.
Applicants should have recently completed, be under examination for, or be close to submitting a PhD. Starting salary is between AUD$57,187 and $77,598 per annum, plus 17% pension contribution. Funds for relocation and travel will also be available.
QUT\'s Science and Engineering Faculty has an active and growing group with research strengths in cryptography, network security, and digital forensics, with a leading national profile and strong international links. QUT is investing heavily in science and technology research, with a new $240 million facility in the heart of Brisbane\'s central business district housing many interdisciplinary research groups, including information security. Brisbane is a city of 2 million people with a high quality of living, and many of Queensland\'s stunning beaches and wilderness are less than half an hour away.
Two Ph.D. studentships, Royal Holloway, University of London, UK
The Government Communications Headquarters (GCHQ) in Cheltenham, UK, has agreed in principle to sponsor two PhD/Doctoral Studentships to be held with the Information Security Group of Royal Holloway (University of London) in the area of cryptography. The studentships will be funded for a period of 3.5 years, starting in September 2013. The two studentships available are as follows:
A Computational Algebra Approach to Learning with Errors
Supervisors: Dr Carlos Cid and Prof. Sean Murphy
Randomness in Cryptography – Theory Meets Practice
Supervisor: Prof. Kenny Paterson
Note that the studentships are only open to UK nationals and the successful candidates will be required to spend in the region of 2 - 4 weeks per year at GCHQ headquarters in Cheltenham. To be considered for this studentship, candidates must therefore be prepared to undergo GCHQ\'s security clearance procedures.

Post-doc in Security and Privacy
Code: 2013-01-491 (in PDF)
Deadline for applications: January 6th, 2013 (might be extended)
We are seeking highly motivated candidates with a strong background and interest in IT security and/or privacy who have finished or will finish soon their Doctorate/PhD in Computer Science or a related discipline.
Preference will be given to candidates with experience in at least one of these areas:
Application security, in particular web application security
Secure engineering, in particular software security, assurance for open source projects
Privacy and transparency enhancing technologies
Security, privacy and compliance management for cloud computing
We expect excellent research and contributions to our teaching program. The position will be part of the ongoing research activities at the Security in IT research group. We actively support publication and presentation of research at the top international conferences and offer an internationally well-connected, interdisciplinary and engineering-oriented work environment.
The position is funded by the university and not bound to a specific project (i.e., it is a \"Landesstelle\"). The position is initially limited to 2 years but may be extended. Compensation follows the Tarifvertrag für die Technische Universität Darmstadt (TV - TU Darmstadt). The Technische Universität Darmstadt aims at increasing the number of female researchers and therefore explicitly encourages women to apply. Severely handicapped will be preferred, given equal qualification.
Applications must include:
List of publications and copies of two selected publications
