The 2014 Election for Directors of the IACR Board is now open. Eligible IACR members may vote now through November 15th using the Helios cryptographically-verifiable election system. You may vote as often as you wish, but only your last vote will be counted.
Eligible members of the IACR (generally people who attended an IACR conference or workshop in 2013) should have received voting credentials from email@example.com, sent to their email address of record with the IACR. Questions about this election may be sent to firstname.lastname@example.org.
More information about the candidates can be found at the IACR elections page.
We offer one PhD scholarship to support a PhD student to work on a project which aims to explore practical privacy-preserving solutions for cloud data mining-as-a-service. The candidate is expected to submit a PhD thesis based on the research.
Candidates should have a Master degree in Computer Science, Knowledge of cryptographic protocols, data mining algorithms and cloud computing architecture. Publications in database security and privacy will be regarded as an additional merit.

multiplications on low hamming weight constants. We give very efficient instances of STK, in particular, a 128-bit tweak/key/state block cipher Deoxys-BC that is the first AES-based ad-hoc tweakable block cipher. At the same time, Deoxys-BC could be seen as a secure alternative to AES-256, which is known to be insecure in the related-key model. As another member of the TWEAKEY framework, we describe Kiasu-BC, which is a very simple and even more efficient tweakable variation of AES-128 when the tweak size is limited to 64 bits.
In addition to being efficient, our proposals, compared to the previous schemes that use AES as a black box, offer security beyond the birthday bound. Deoxys-BC and Kiasu-BC represent interesting pluggable primitives for authenticated encryption schemes, for instance, OCB instantiated with Kiasu-BC runs at about 0.75 c/B on Intel Haswell. Our work can also be seen as
advances on the topic of secure key schedule design for AES-like ciphers, describing several proposals in this direction.
