摘要： A default pre-shared key is provided from a first device to a second device. The first device is configured to control network access to a network. A first authentication request is obtained at the first device from a third device. The first authentication request includes data indicative of the second device. A first response to the first authentication request is provided from the first device to the third device. The first response includes the default pre-shared key. A second authentication request containing a private pre-shared key and the data indicative of the second device is obtained at the first device from the third device. Stored data at the first device is updated in response to the second authentication request with the private pre-shared key and the data indicative of the second device to provision the first device to provide network access to the network to the second device.

摘要： Techniques and architecture are described for securing traffic between nodes of a network against quantum computing attacks. For example, a first node of a network generates a random number input string and provides the random number input string to a second node. The first node may use the random number input string to generate at least one first key and an associated identifier. The first node may forward the associated identifier to the second node. Using the random number input string, the second node may generate at least one second key. Based at least in part on the associated identifier, the second node may select the at least one second key as a common encryption key. The at least one second key and the at least one first key are identical. Based at least in part on the common encryption key, the nodes may encrypt and decrypt traffic between them.

摘要： Provisioning site specific policies in wireless Local Area Networks (LANs) deployments may be provided. First, a master computing device may receive a discovery request and data associated with neighbor access devices learned by a first access device. Then a Radio Frequency (RF) continuity space may be determined based on the received data associated with the neighbor access devices learned by the first access device. Next, a site tag associated with the determined RF continuity space may be determined. Then the site tag associated with the determined RF continuity space may be assigned to the first access device. For the first access device, a worker computing device having the site tag may be selected.
