ANR “GeoLMI”

Participants : J.-C. Faugère, M. Safey El Din [contact] .

The GeoLMI project(http://homepages.laas.fr/henrion/geolmi/ ) aims at developing an algebraic and geometric study of linear matrix inequalities (LMI) for systems control theory. It is an interdisciplinary project at the border between information sciences (systems control), pure mathematics (algebraic geometry) and applied mathematics (optimisation). The project focuses on the geometry of determinantal varieties, on decision problems involving positive polynomials, on computational algorithms for algebraic geometry, on computational algorithms for semi-definite programming, and on applications of algebraic geometry techniques in systems control theory, namely for robust control of linear systems and polynomial optimal control.

ECRYPT II - European Network of Excellence for Cryptology

Participants : J.C. Faugère [contact] , L. Perret, G. Renault, L. Bettale.

ECRYPT II - European Network of Excellence for Cryptology II is a 4-year network of excellence funded within the Information & Communication Technologies (ICT) Programme of the European Commission's Seventh Framework Programme (FP7) under contract number ICT-2007-216676. It falls under the action line Secure, dependable and trusted infrastructures. ECRYPT II started on 1 August 2008. Its objective is to continue intensifying the collaboration of European researchers in information security. The ECRYPT II research roadmap is motivated by the changing environment and threat models in which cryptology is deployed, by the gradual erosion of the computational difficulty of the mathematical problems on which cryptology is based, and by the requirements of new applications and cryptographic implementations. Its main objective is to ensure a durable integration of European research in both academia and industry and to maintain and strengthen the European excellence in these areas. In order to reach this goal, 11 leading players have integrated their research capabilities within three virtual labs focusing on symmetric key algorithms (SymLab), public key algorithms and protocols (MAYA), and hardware and software implementations associate (VAMPIRE). They are joined by more than 20 adjoint members to the network who will closely collaborate with the core partners. The team joins the European Network of Excellence for Cryptology ECRYPT II this academic year as associate member.

Joint LIAMA Project ECCA

ECCA (Exact/Certified Computation with Algebraic systems) is a LIAMA project (Reliable Software Theme) focusing on polynomial system solving. The partners are INRIA, CNRS, and CAS (Chinese Academy of Sciences). The general objectives of this project are mainly the same as those of SALSA.

ANR International Grant “EXACTA”

Participants : D. Wang [contact] , J.-C. Faugère, D. Lazard, L. Perret, G. Renault, M. Safey El Din.

The main objective of this project is to study and compute the solutions of nonlinear algebraic systems and their structures and properties with selected target applications using exact or certified computation. The project consists of one main task of basic research on the design and implementation of fundamental algorithms and four tasks of applied research on computational geometry, algebraic cryptanalysis, global optimization, and algebraic biology. It will last for three years (2010–2012) with 300 person-months of workforce. Its consortium is composed of strong research teams from France and China (KLMM, SKLOIS, and LMIB) in the area of solving algebraic systems with applications.
