Embodiment Construction

[0053] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0054] Embodiment 1 of the present invention provides a network device authentication and key management method, such as figure 2 as shown,

[0055] mainly include:

[0056] In step 201, the network device generates a network key (NK).

[0057] The network device can generate NK according to the obtained password key, which specifically includes: the user enters the password from the user interface of the network device, the length of the password cannot exceed the maximum length set by the user interface, and the network device inputs the password entered by the user into the Pseudo-random function is used to calculate and obtain NK with a fixed length.

[0058] In addition to obtaining NK through the user inputting a password, if the network device implements the function of simple security configuration accord...

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.

Description

technical field [0001] The invention relates to heterogeneous network fusion technology, in particular to a network device and its authentication and key management methods. Background technique [0002] At present, the home network can be accessed through a variety of network technologies, such as: Ethernet IEEE 802.3, power line communication (PLC, Power Line Communication), coaxial cable (MoCA, Multimedia over Coax Alliance) and wireless local area network (WiFi, Wireless Fidelity) technology And so on, each access technology corresponds to the physical (PHY) layer and media access control (MAC, Media Access Control) layer of the network system model. The integration of these heterogeneous network technologies is the basis for realizing home network information sharing and seamless connection. [0003] like figure 1 as shown, figure 1 It is a structural schematic diagram of heterogeneous network fusion in the prior art. Device 1 and Device 2 in the figure are home net...
