摘要： A hierarchical key generation and distribution mechanism for a computer system in which devices are organized into secure enclaves. The mechanism enables network access to be tailored to approximate minimum needed privileges for each device. At the lowest level of the hierarchy, keys are used to form security associations between devices. Keys at each level of the hierarchy are generated from keys at a higher level of the hierarchy and key derivation information. Key derivation information is readily ascertainable, either from identifiers for devices or from within messages, supporting hardware offload of cryptographic functions. Because keys may be generated based on the enclaves in which the hosts participating in a security association are located, the system includes a mechanism by which devices can discover the enclave in which they are located.

摘要： Reliably identifying an AP through which a user device is accessing one or more networks, and reliably determining the current network location of the user device. An AP and network location may be reliably identified using a set of transmitter fingerprints unique to the AP or network location, respectively. In response to a user device receiving at least one signal from at least one unknown entity, a transmitter fingerprint set of the at least one entity may be determined from the at least one signal. It then may be determined whether the at least one entity is an AP having an ID known to the user device, and/or whether the current network location is known by the user device. The user device may determine information that may be divulged with the at least one entity based on this determination.

摘要： A fingerprint table or other type of data structure including a plurality of entries may be provided, each entry including a transmitter fingerprint set of a respective network location. Determining whether a current network location is a network location known to a user device may include comparing a determined transmitter fingerprint set of the entity with the transmitter fingerprint set of one or more fingerprint table entries. A user interface may be provided that enables a user to control when a transmitter fingerprint set is determined, compared with fingerprint table entries and/or recorded.

摘要： A wireless system includes at least one network computing system, a proxy server, a controller, and wireless devices. When a wireless device is already a member of a first group but moves into range of a second group, that device may initiate a request to join the second group, thereby ensuring that the wireless device can send and receive information through the second group. The proxy server maintains a list of authorized wireless devices and their primary controller, thereby routing information from one or more network computing systems to the proper controller, so that the wireless device may receive information from one of those network computing systems as necessary. When the wireless device becomes joined to a new controller, the proxy updates its list, thus ensuring continuity between the wireless device and the one or more network computing systems.
