    摘要： In a communications system comprising a number of base stations, each base station communicating over a shared communication channel with a plurality of registered stations and controlling the network cell formed by said plurality of registered stations, a method is described for dynamically registering and deregistering mobile stations. Each station owns a unique address and is allocated a local identifier at registration time. Each network cell owns a unique cell identifier known to all registered stations belonging to this network cell. Base stations manage cell members data uniquely associating the unique address and the local identifier corresponding to each one of the mobile stations belonging to their network cell. A registration request is sent to a selected base station by a registering mobile station, comprising the unique cell identifier of the network cell controlled by the selected base station and the unique address of the registering mobile station; the selected base station detects in its cell members data any conflicting registered station whose unique address matches the unique address of the registering mobile station and sends an address check packet to any conflicting registered station, comprising the unique address of the conflicting registered station, its local identifier and the identifier of the network cell it controls. A receiving registered mobile station sends to the selected base station, an acknowledgement to the address check packet if its unique address, the local identifier of its owning base station and its network cell identifier all match with the ones carried by the address check packet. The selected base station rejects the registration request it it receives an acknowledgement to its address check packet. The same address check packet is used to deregister inactive stations.

    摘要： This invention deals with a safe key distribution and authentication in a data communication network (e.g. wireless LAN type of network).
    The network includes a network manager to which are connected, via a LAN wired circuit, one or more base stations. Individual remote stations are, in turn, wirelessly connected to an installed base station.
    One essential function for achieving security in such a network, is a mechanism to reliably authenticate the exchanges of data between communicating parties. This involves the establishment of session keys, which keys need to be distributed safely to the network components. An original and safe method is provided with this invention for key distribution and authentication during network installation, said method including using the first installed base station for generating a network key and a backbone key, and then using said first installed base station for subsequent remote station or additional base station installations while avoiding communicating said network key.
