Carrier sense multiple access with collision avoidance - Wikipedia, the free encyclopedia

Carrier sense multiple access with collision avoidance

Carrier sense multiple access with collision avoidance ( CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by transmitting only when the channel is sensed to be "idle". When they do transmit, nodes transmit their packet data in its entirety.

Laboratoire 802.1x/PEAP/Radius

Cette mise en oeuvre répond à la faille de sécurité du déploiement de WPA/WPA2 Personal en entreprise. Elle consiste en un déploiement de WPA2 Enterprise avec la méthode PEAP (MS-CHAPv2). On utilisera pour cet exemple :
IEEE 802.3, IEEE 802.11n, IEEE 802.11i, IEEE 802.1x, Radius, PEAP (MS-CHAPv2), un fichier plat d’utilisateurs sont utilisés avec un seul PC (Supplicant et Radius Server) et un point d’accès (NAS). Des variantes topologiques et protocolaires sont possibles.
Il s’agit ici de distinguer les concepts d’authentification et d’encryption dans les différentes couches du modèle OSI.

IEEE 802.11a-1999 - Wikipedia, the free encyclopedia

IEEE 802.11a-1999 or 802.11a was an amendment to the IEEE 802.11 wireless local network specifications that defined requirements for an orthogonal frequency division multiplexing (OFDM) communication system. It was originally designed to support wireless communication in the unlicensed national information infrastructure (U-NII) bands (in the 5-6 GHz frequency range) as regulated in the United States by the Code of Federal Regulations, Title 47, Section 15.407.
