Abstract: In embodiments of the present disclosure, there is provided a method for authenticating an access point. In the method, a request for joining a network is received from an access point. A neighbor authentication notification is transmitted to the access point for obtaining an authentication code from a neighbor access point that is connected in the network in accordance with a determination that the access point is verified. The authentication code that is generated by the neighbor access point is received from the access point. The access point is accepted to join the network in accordance with a determination that the authentication code is valid. Embodiments of the present disclosure present a safe and effective way for authenticating the access point that is requesting to join the network, which provides enhanced authentication and increases the security level of the network.

Abstract: Systems and methods are provided for a detection and defense system relating to a network connection sharing application. For example, the system can simulate a request for a network password using a conventional application that shares this information. The application may be implemented on, for example, a mobile device or a virtual machine (VM). In some embodiments, the mobile device/VM attempts to establish a network connection to an access point (AP) using the shared password over a tunnel established between the AP and mobile device/VM. If the mobile device/VM can connect to the AP, an assumption may be made that the user credentials have been leaked and a potential security risk exists. An alert can be sent to a network administrator of the communication network (e.g., to perform an action, etc.). The action may include, for example, changing the password, removing access from one or more users, and the like.

Abstract: Some examples relate to use of a three-address scheme for forwarding frames in a wireless mesh network (WMN). In an example, a node in a WMN may receive an Ethernet packet from a station outside of the WMN. The Ethernet packet may include a first address scheme comprising a destination address (DA) field, and a source address (SA) of the Ethernet packet. The Ethernet packet may be encapsulated in a second Ethernet packet comprising second address scheme. The second Ethernet packet may be encapsulated in an IEEE 802.11 frame comprising a third address scheme.

Abstract: In embodiments of the present disclosure, there is provided an approach for performing channel scan by utilizing a target wake time (TWT) mechanism. According to embodiments of the present disclosure, a compound AP transmits, to an uplink AP, a request to negotiate a schedule for a TWT session. The compound AP receives a response to the request from the uplink AP. The response comprises timing information of the TWT session. Then, the compound AP performs channel scan during a sleep period determined from the timing information. Data transmission between the compound AP and the uplink AP is disabled during the sleep period. Embodiments of the present disclosure provide an effective way for performing the channel scan, thereby ensuring data delivery and enhancing connection robustness between the compound AP and the uplink AP.

Abstract: Systems and methods for improving the performance and stability of bonding radios are provided. One method includes receiving a packet from a client device. Next, the method includes determining whether the received packet is an expected next packet and transmitting the received packet to a next destination if the received packet is the expected next packet. In an event the received packet is not the expected next packet, transmitting the received packet to a queue, setting a timer to wait for the expected next packet, and transmitting a message to the sender of the received packet requesting that the expected next packet be sent.
