摘要： Group key management techniques are applied to generating pair-wise keys for point-to-point secure communication applications. Nodes participating in a secure communication group each receive a group key and associated policy information. When a first node wishes to establish a secure point-to-point connection to a second node, the first node derives a pairwise key from the group key and policy information, for example, by hashing the group key and information identifying the two nodes. As a result, a pairwise key is generated without exchanging negotiation messages among the two nodes and without expensive asymmetric cryptographic computation approaches.

摘要： A system for determining security associations using binary output sequences is described. In an example systematic embodiment, a first device is coupled over a network to a second device. Each device includes a processor and an indicator mechanism coupled to the processor. The indicator mechanism is configured to output a binary representation of a security state established between the devices to a user in perceivable proximity to at least one of the devices. A computer readable storage medium is coupled to the processor and includes executable instructions for the processor. The instructions when executed by the processor initiate a security transaction between the devices. The security transaction includes a protocol that uses one or more public keys to establish a security state between the devices. The indicator mechanism then outputs the binary representation to the user based on the established security state.

摘要： Methods and systems of providing security backup services to a home network are described. In one embodiment, the gateway for a home network is registered with a service provider. A network device is enrolled with the home network, and periodically reenrolls. The device detects whether the gateway has been replaced between enrolling and reenrolling, and if it has been replaced, determines whether the new network gateway has been endorsed by the service provider.

摘要： Systems, methods, and other embodiments associated with processing secure network traffic are described. One example method includes determining whether a device is a preconfigured member of a group key system. If the device is not a preconfigured member then the method selectively establishes membership in the group key system by requesting membership from a group controller. The example method may also include receiving a set of keys from the group controller and being assigned a role by the group controller. The method may further include processing secure network traffic as an inspection point, a rewriting point, and/or a validation point based on the received set of keys and the assigned role(s).

摘要： One embodiment of an inventive networking environment includes clients called sending clients because they send network content through a network, and clients called receiving clients because they receive the network content from the sending clients through the network. Both sending clients and receiving clients are “clients” in that they rely on a management server to orchestrate the secure transfer of information from sending clients to receiving clients.

摘要： Access to content works, or other information, may be granted based upon device capabilities. A content approving network device, or other device, may make a comparison of a device's components with permissions and then determine if access to a content work is allowed based on the comparison. Methods may include asserting capabilities of a device, comparing the capabilities to permissions, and approving access to content based on the capabilities and permissions comparison.
