Selon le cas d\u2019usage, des datagrammes UDP peuvent suffire pour des messages l\u00e9gers et non critiques en \u00ab fire-and-forget \u00bb. En revanche, la redondance et les accus\u00e9s de r\u00e9ception offerts par TCP sont souvent indispensables pour une collecte de donn\u00e9es fiable, devenant le seul choix viable. \n\nDes milliards d\u2019objets IoT viennent chaque ann\u00e9e s\u2019ajouter \u00e0 un r\u00e9seau d\u00e9j\u00e0 surcharg\u00e9.

Les <span>\u00e9quilibreurs de charge<\/span>, <span>serveurs<\/span> ou <span>brokers<\/span> ont les m\u00eames exigences : ils ne doivent \u00e9tablir une connexion qu\u2019avec des dispositifs dont l\u2019identit\u00e9 est v\u00e9rifi\u00e9e. Dans des sc\u00e9narios simples ou en phase de d\u00e9veloppement, un secret partag\u00e9 peut suffire, mais rapidement, une solution plus robuste devient n\u00e9cessaire. Les dispositifs doivent pr\u00e9senter un <span>certificat client<\/span>, souvent conforme \u00e0 la norme <span>X.509<\/span>.

Le sc\u00e9nario id\u00e9al, lorsque tout fonctionne, peut \u00eatre mis en \u0153uvre avec un effort mod\u00e9r\u00e9. Mais beaucoup de questions doivent aussi trouver une r\u00e9ponse : que se passe-t-il \u00e0 l\u2019expiration d\u2019un certificat ? En cas de compromission ? Si la cl\u00e9 priv\u00e9e de l\u2019autorit\u00e9 est divulgu\u00e9e ?\n<br \/><br \/>Quoi qu\u2019il en soit, une r\u00e8gle simple mais souvent oubli\u00e9e doit \u00eatre respect\u00e9e scrupuleusement : ne jamais inventer ses propres <span>primitives cryptographiques<\/span> ! Il est beaucoup trop facile de faire des erreurs en cherchant \u00e0 r\u00e9inventer la roue.
