Cette science est devenue omnipr\u00e9sente dans nos activit\u00e9s quotidiennes, ne serait ce que par les paiements par cartes et nos achats sur INTERNET.<\/span><\/span><\/p>\n

La crypto est une discipline math\u00e9matique, mais m\u00eame si vous avez un souvenir \u00ab\u00a0mitig\u00e9\u00a0\u00bb de vos cours de maths au lyc\u00e9e, la connaissance du fonctionnement des transactions informatiques <\/span><\/span>s\u00e9curis\u00e9 <\/span><\/span> vous <\/span><\/span>permettra d\u2019avoir les bases pour comprendre les enjeux s\u00e9curitaires de plus en plus pr\u00e9gnants dans les syst\u00e8mes que nous utilisons au quotidien.<\/span><\/span><\/p>\n

L\u2019atelier d\u00e9butera par un ra<\/span><\/span>ppel des pr\u00e9sentations pr\u00e9c\u00e9dentes ( cryptographie \u00e0 clef publique RSA ) ce qui permettra aux personnes n\u2019ayant pas pu assister aux ateliers pr\u00e9c\u00e9dent de suivre.<\/span><\/span><\/p>\n

Des outils logiciels math\u00e9matiques comme CALC, OCTAVE, SCILAB seront pr\u00e9sent\u00e9s.<\/span><\/span><\/p>\n
