Notes on the design and analysis of Simon and Speck - IACR

WebSimon is een familie van lichtgewicht blokcijfers die in juni 2013 openbaar zijn gemaakt door de National Security Agency (NSA). Simon is geoptimaliseerd voor prestaties in hardware-implementaties, terwijl het zusteralgoritme, Speck , is geoptimaliseerd voor software-implementaties. De NSA begon in 2011 aan de Simon- en Speck-cijfers te werken. WebMar 7, 2024 · Abstract. At CRYPTO'19, Gohr proposed a new cryptanalysis strategy based on the utilisation of machine learning algorithms.
