摘要： A system and method for providing secure communication between nodes (102, 106, 107) in a wireless multihopping communication network (100). The system and method achieve secure communication in a multihopping wireless network (100) by, for example, providing a transport medium for transmission of multihopping authentication messages (400) by the infrastructure devices, such as intelligent access points (106) or wireless routers (107), and user devices, such as mobile nodes (102). The authentication messages (400) are used to verify the identity of a node (102, 107) to thus permit the node (102, 107) to communicate within the network (100). The system and method further use, for example, encryption techniques for protecting the content data packet (1000) traffic being transmitted the nodes (102, 106, 107) within the wireless network (100).

摘要： A method for transmitting groupcast data in a wireless mesh communication network as provided improves security of groupcast data. The method comprises processing, at a supplicant node, authentication handshake data received from an authenticator node, wherein the supplicant node is a next-hop neighbor of the authenticator node away from a root node. The supplicant node then stores a group transient key (GTK) received from the authenticator node. Next, the supplicant node processes authentication handshake data received from a third node, wherein the third node is a next-hop neighbor of the supplicant node away from the root node. The GTK is then transmitted from the supplicant node to the third node. Encrypted groupcast data are then generated at the supplicant node by using the GTK to encrypt groupcast data received from the authenticator node. Finally, the encrypted groupcast data are transmitted from the supplicant node to the third node.
摘要翻译：一种用于在无线网状通信网络中发送组播数据的方法，提供了群播数据的安全性。所述方法包括在请求方节点处处理从认证器节点接收到的认证握手数据，其中所述请求者节点是远离根节点的认证器节点的下一跳邻居。然后，请求者节点存储从认证器节点接收的组瞬态密钥（GTK）。接下来，请求者节点处理从第三节点接收的认证握手数据，其中第三节点是远离根节点的请求者节点的下一跳邻居。然后，GTK从请求者节点传送到第三个节点。然后，通过使用GTK来加密从认证者节点接收的群播数据，在请求方节点生成加密的群播数据。最后，加密的群播数据从请求者节点传送到第三节点。
