Vladimír Sedláček (Masaryk University and at Ca'Foscari University, Venice.), fera un exposé le jeudi 10 juin à 14h (en visio).
Abstract: Selecting elliptic curves suitable for cryptographic applications is a difficult task. Widely used standards such as ANSI X9.62 define elliptic curves with specific parameters, though often unsatisfactorily explained. As there are documented instances of standards being manipulated, it is hard to trust such curves selected in a non-transparent way. The talk will introduce a new methodology and a tool to help spot any unexpected behavior of standard curves and potentially find a problem; a demonstration of the tool will also be included.
