Collaboration with ANU
Participants : Shi Bai, Richard Brent, Judy-anne Osborn, Paul Zimmermann.
In the context of the “associate team” ANC (Algorithms, Numbers, Computers), which started in 2008 (http://www.loria.fr/~zimmerma/anc.html ), between the Cacao project-team and the team of Richard Brent at the Australian National University (ANU), several visits were organized in 2009: R. Brent and J.-A. Osborn visited LORIA for two weeks in April-May, P. Zimmermann visited ANU for one month in July, and S. Bai visited LORIA for one month in October-November.
Collaboration with Tsukuba, Japan
Participants : Jérémie Detrey, Nicolas Estibals, Guillaume Hanrot.
In the context of the AYAME Junior Program on the subject of “Software and Hardware Components for Pairing-Based Cryptography” between the Cacao project-team, the Arénaire project-team and the Laboratory of Cryptography and Information Security (LCIS) of the University of Tsukuba (Japan), J.-L. Beuchat (Univ. Tsukuba) visited us for one week in February 2009. During this week, he worked with J. Detrey and N. Estibals to complete a paper for the CHES 2009 conference [8] , for which they received a Best Paper Award. An extended version of this work was also submitted to the IEEE Transactions on Computers [17] .
J.-L. Beuchat visited us again for one week in September 2009, along with T. Teruya, Ph.D. student at the University of Tsukuba. This visit was the occasion for us to continue working on the topic of pairings over genus-2 supersingular hyperelliptic curves. This work had been started during the visit of J. Detrey and G. Hanrot at Tsukuba in February 2008, and is now nearing completion.
Other visits
Part of an ongoing collaboration with F. Rodríguez-Henríquez, J. Detrey and N. Estibals spent three weeks in November 2009 at the CINVESTAV (Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional ) in Mexico City. There, they continued their work on the automatic generation of finite-field multipliers, for use in hardware pairing coprocessors. J. Detrey also gave a twelve-hour course on pairings to the Master students of the CINVESTAV.
