In this talk, we show some interesting relations between the problem of attacking multiple encryption schemes and attacking knapsack systems. The underlying relation, of problems of a bi-composite nature, allows introducing a series of algorithms for the dissection of these … Continue reading Colloquium: Tuesday, January 5, 2pm.
