Dans le cadre des r\u00e9seaux auto-organis\u00e9s sans fil, le groupe s\u00e9curit\u00e9 a d\u00e9fini une architecture de gestion de la confiance bas\u00e9e sur le service AAA pour les r\u00e9seaux ad hoc\/mesh avec l\u2019hypoth\u00e8se que le r\u00e9seau b\u00e9n\u00e9ficie d\u2019une connectivit\u00e9 intermittente avec le r\u00e9seau de l\u2019op\u00e9rateur. Tout noeud, d\u2019un op\u00e9rateur ou d\u2019un simple usager, peut h\u00e9berger des fonctions AAA pour peu qu\u2019il dispose d\u2019une architecture mat\u00e9rielle telle que d\u00e9crite dans le brevet 07 56559 qu\u2019elle a d\u00e9pos\u00e9.<\/p>\n
\nDans le cadre des r\u00e9seaux de capteurs, une solution de s\u00e9curit\u00e9 tr\u00e8s simple, et facile de d\u00e9ploiement a \u00e9t\u00e9 con\u00e7ue dans le cadre du projet ANR CAPTEURS de suivi de la cha\u00eene du froid. Elle a \u00e9t\u00e9 impl\u00e9ment\u00e9e et test\u00e9e sur de v\u00e9ritables capteurs de type Tmote sky, prouvant ainsi sa viabilit\u00e9. D\u2019autres travaux portant sur la s\u00e9curit\u00e9 de
\nl\u2019agr\u00e9gation des donn\u00e9s, sur la distribution des cl\u00e9s et l\u2019authentification d\u2019une source de diffusion ont aussi \u00e9t\u00e9 r\u00e9alis\u00e9s.<\/p>\n
\nDes r\u00e9sultats tr\u00e8s int\u00e9ressants appliqu\u00e9s aux r\u00e9seaux IPv6, r\u00e9seaux Peer-to-Peer (P2P) et r\u00e9seaux de capteurs et visant \u00e0 am\u00e9liorer la s\u00e9curit\u00e9 globale des \u00e9changes ou un meilleur contr\u00f4le du trafic ont aussi \u00e9t\u00e9 obtenus. Ces r\u00e9sultats pr\u00e9sent\u00e9s \u00e0 l\u2019IETF sous forme de plusieurs contributions soul\u00e8vent l\u2019int\u00e9r\u00eat de la communaut\u00e9 et s\u2019av\u00e8rent particuli\u00e8rement int\u00e9ressants pour les \u00e9quipements de faibles capacit\u00e9s.
\nLa s\u00e9curit\u00e9 des mobiles est aussi un dossier sensible. Un effort est port\u00e9 sur la s\u00e9curit\u00e9 des r\u00e9seaux personnels : en enrichissant les algorithmes de s\u00e9curit\u00e9 de protocoles ad\u00e9quats et de syst\u00e8mes sp\u00e9cialis\u00e9s.<\/p>\n
\nL\u2019\u00e9quipe a aussi introduit des modifications cryptographiques qui peuvent am\u00e9liorer la s\u00e9curit\u00e9 dans les r\u00e9seaux mobiles. Un progiciel est disponible.<\/p>\n","protected":false},"excerpt":{"rendered":"
