Visit from PhD student David Lucas

The Algebra group was visited 30th October till 10th November by PhD student David Lucas from University of Grenoble-Alpes in France. David Lucas is looking at non-cryptographic solutions for security issues with cloud computing, and during the visit worked with Johan Rosenkilde on certificates for linear algebraic computations: a cloud service computes e.g. the determinant of a large matrix for your constrained device, and you wish to be sure (or very confident) that the answer is correct. By letting the cloud server compute a little bit more, clever protocols allows you to prove that the answer is correct without having to recompute it yourself.

The visit was funded by DTU and the IFD Science research project “Correcting the Cloud”, granted to Johan Rosenkilde and David’s superviser ClĂ©ment Pernet.
