Abstract: A method and apparatus for dynamic medium switching in a hybrid network. A method for packet transmission by a combo device includes maintaining a wireless network confidence rating value that is indicative of packet transfer reliability of a wireless network accessed by the device. A wired network confidence rating value that is indicative of packet transfer reliability of a wired network accessed by the device is also maintained. One of the wireless network and the wired network to be used for initial transmission of the data packet is selected based on which of the wireless confidence rating value and the wired confidence rating value is indicative of a higher likelihood of the packet being successfully transmitted. The packet is routed to be transmitted via the selected network.

Abstract: Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key.

Abstract: In a disclosed embodiment, a method for communication in a network includes receiving, at a first device registered to the network, a physical layer (PHY) frame that includes a PHY header and a MAC header. The PHY frame may further include a MAC payload. The PHY header includes a destination address field. The method further includes comparing a network address of the first device to the destination address field to determine whether the destination address field stores a value having the same number of bits as the network address. When the comparison indicates that the value stored by the destination address field does not have the same number of bits as the network address, the method skips decoding the MAC header and the MAC payload.
