摘要： A system and method for enabling a zero configuration nomadic wireless and wired computing environment presenting a just works experience is presented. The system examines predefined user preference or profile settings to determine to which of a competing number of wireless networks available it should connect, and what type of authentication should be used for such connection. Nomadic wireless computing between infrastructure wireless networks and ad hoc wireless networks may be accomplished without further user intervention required in an auto mode. Also, both infrastructure only and ad hoc only modes are available through the system of the invention. Further, the user may set a preference for infrastructure or ad hoc modes in the auto mode. With an infrastructure mode preference set, the system will automatically detect and transfer connectivity to a newly available infrastructure wireless network if the user was previously operating off-line or in ad hoc mode.

摘要： A method for setting up and managing secure data/audio/video links with secure key exchanges, authentication and authorization is described. An embodiment of the invention enables establishment of a secure link with limited privileges using the machine identifier of a trusted machine. This is particularly useful if the user of the machine does not have a user identifying information suitable for authentication. Furthermore, the presentation of a default user identifying information by a user advantageously initiates intervention by a system administrator instead of a blanket denial. This decentralized procedure allows new users access to the network without having to physically access a centralized facility to present their credentials. Another embodiment of the invention enables a remote user to connect to a secure network with limited privileges.

摘要： A power management scheme for use in a wireless device reduces the power consumption of the network interface module of the wireless device by selectively putting the network interface module into a low-power state for an idle time. The length of the idle time is calculated such that the amount of delayed traffic data accumulated is expected to be less than or equal to a pre-selected threshold when the network interface module is put in the low-power state for the calculated idle time. The amount of delayed traffic data as a function of the idle time is modeled using average inter-arrival and service rates that are derived from traffic statistics data.

摘要： Disclosed are methods for a client, having established one set of security keys, to establish a new set without having to communicate with an authentication server. When the client joins a group, master session security keys are derived and made known to the client and to the group's access server. From the master session security keys, the access server and client each derive transient session security keys, used for authentication and encryption. To change the transient session security keys, the access server creates “liveness” information and sends it to the client. New master session security keys are derived from the liveness information and the current set of transient session security keys. From these new master session security keys are derived new transient session security keys. This process limits the amount of data sent using one set of transient session security keys and thus limits the effectiveness of any statistical attacker.
摘要翻译：已经公开了已经建立了一组安全密钥的客户端的方法来建立新的集合而不必与认证服务器进行通信。当客户端加入一个组时，主会话安全密钥被导出，并被客户机和组的访问服务器所知。从主会话安全密钥，访问服务器和客户端都派生用于认证和加密的瞬态会话安全密钥。要更改瞬态会话安全密钥，访问服务器创建“活动”信息并将其发送给客户端。新的主会话安全密钥来源于活动信息和当前的一组暂存会话安全密钥。从这些新的主会话安全密钥导出新的临时会话安全密钥。此过程限制使用一组瞬态会话安全密钥发送的数据量，从而限制任何统计攻击者的有效性。

摘要： The invention detects and responds to events occurring on a computer network medium. When a network media event is detected, network parameters are adjusted, if possible, to adapt to the new circumstances brought about by the event, and traffic may be rerouted if that is appropriate. High-level protocol drivers and network-aware applications are notified of the event so that they may adapt to the changed network circumstances. Sometimes, as a result of the network media event, the computer communicates with other devices on the network to discover the state of network entities, network elements, and services.

摘要： The present invention relates to a system for automatic detection and configuration of network parameters. The system includes a first computer system for communicating to a network and at least a second computer system for providing network information. The first computer system queries the network and receives network information from the at least a second computer system before a network identification has been established for the first computer system. The system further includes a storage for storing at least one configuration associated with a network interface. The first computer system configures the network interface based upon the network information received from the at least a second computer system. Also, the first computer system may configure the network interface by determining a network identification associated with the network information and matching the at least one configuration with the network identification.

摘要： A computer system attempts to authenticate with a server to gain authorization to access a first network. It is determined by the server that the computer system is not authorized to access the first network. The computer system is given authorization to access a second network for at least the purpose of downloading files (e.g., signup and configuration files) needed to access the first network. A user-interface for receiving user-entered signup information is automatically presented at the computer system. A first schema-based document including user-entered information is transferred to the server. If the server determines that the user-entered information is appropriate, a second-schema document, which includes an indication of authorization to access the first network (e.g., a user-identifier and password), is received. A third schema-based document is executed at the computer system to compatibly configure the computer system for accessing the first network.

摘要： In a method for controlling access to a network by a wireless client and a network, an access point on the network receives a request for a network address broadcast by the wireless client. The request is passed to an address server, which assigns a temporary address to the wireless client and provides the address of the access point. The wireless client then initiates a secure link with the access point based on the network address assigned by the address server and the address of the access point. If the secure link is not established before the temporary address expires, then wireless client is denied access to the network.
