Abstract: Disclosed is a data transmission method. When it is determined that a transmitting end device and a receiving end device both support a link binding capability, a binding group is established; when data is selected to be transmitted by a binding link in the binding group, the data to be transmitted is encapsulated according to a binding data format and is transmitted through the binding link; and when data is selected to be transmitted by a non-binding link, the data to be transmitted is encapsulated according to a common data format and is transmitted through the non-binding link. Also disclosed are a data transmission apparatus and a computer storage medium.

Abstract: A data transmission method, multi-medium access point and multi-medium client are disclosed. The method includes: a multi-medium access point (AP) acquiring a current wireless local area network (WLAN) operating mode of an opposite end multi-medium client (Client) from the opposite end multi-medium Client; and the multi-medium AP comparing an address of a target device to which a data packet to be sent is sent with an address of the opposite end multi-medium Client, if they are different, judging whether both a current WLAN operating mode of the multi-medium AP and the current WLAN operating mode of the opposite end multi-medium Client are three-address modes or not, and if yes, determining that the data packet to be sent is prohibited from being sent through a wireless fidelity (WiFi) interface of the multi-medium AP.

Abstract: Provided is a network equipment and an authentication and key management method for the same. The network equipment generates a Network Key (NK); the network equipment performs authentication protocol interaction with opposite communication equipment, and calculates a Basic Session Key (BSK) according to parameters for the authentication protocol interaction and the NK; and the network equipment calculates link Encryption Keys (EKs) used respectively for Media Access Control (MAC) and Physical (PHY) layers using various access technologies according to the BSK, and provides the EKs for respective MAC and PHY layer function modules. With the disclosure, the legality of the equipment is verified by performing an authentication process on the heterogeneous network equipments in one pass, and keys in various MAC layer technologies are managed in a unified way.
