Conclusion
• Actuellement le système quantique est le
graal de la cryptologie : il est et restera
inviolable !
• Mais il souffre encore pour longtemps de sa
lenteur et de sa complexité d’utilisation !!
• Au vu du tableau précédant, le système
Gallego réalise le meilleur compromis mais il
souffre d’un défaut rédhibitoire : il n’est pas
encore commercialisé !!!
Essayez de casser le code qui
suit !
Voici l’alphabet utilisé :

A vous de jouer maintenant !
Si vous réussissez à casser ce code : 1 prix de
1000$ vous sera attribué
Sinon je propose à ceux qui sont intéressés , un
partenariat pour exploiter mon système de
