Abstract[English]
A method and device for optimizing dataflow load in an accelerator of a fully homomorphic encryption (FHE) program are provided. The accelerator is configured with a FHE network including a plurality of permute units, and the method includes obtaining a set of program parameters; obtaining a set of optional orderings; determining optimal program parameters to match an ordering of the set of optimal orderings to yield a required dataflow load; and modifying a FHE program to place coefficients in the permute units and perform the permutations based on the optimal program parameters and matching ordering.[French]
L'invention concerne un procédé et un dispositif d'optimisation de charge de flux de données dans un accélérateur d'un programme de chiffrement entièrement homomorphe (FHE). L'accélérateur est configuré avec un réseau FHE comprenant une pluralité d'unités de permutation, et le procédé comprend l'obtention d'un ensemble de paramètres de programme ; l'obtention d'un ensemble d'ordres facultatifs ; la détermination de paramètres de programme optimaux pour correspondre à un ordre de l'ensemble d'ordres optimaux afin de produire une charge de flux de données requise ; et la modification d'un programme FHE pour placer des coefficients dans les unités de permutation et effectuer les permutations sur la base des paramètres de programme optimaux et de l'ordre correspondant.
