Problems solved by technology

[0018] Although the above method can achieve re-authentication, it needs to rebuild the EAP-initial message and EAP-finish message, which is a conflict with the existing standard framework, and the existing authentication server needs to be upgraded, which increases the difficulty of implementation

Embodiment Construction

[0034] In the embodiment of the present invention, the mobile node MN that supports re-authentication is authenticated once by the authentication device of the visited network, thereby avoiding the change of the existing network equipment and the existing protocol framework during the re-authentication process, and improving the re-authentication efficiency.

[0035] Such as figure 2 As shown, it is a flow chart of a re-authentication method provided by the embodiment of the present invention. The re-authentication in the embodiment of the present invention refers to the re-authentication performed in the visited network after the mobile node MN moves from the home network to the visited network. In order to realize re-authentication, when the mobile node accesses the home network, it needs to complete the first access authentication with the home AAA, and the re-authentication material for re-authentication is generated between the MN and the home AAA (step 201) . Wherein,...

Abstract

The embodiment of the invention discloses a recertification method, a system and an authentication device. The recertification method comprises the steps: judging whether a mobile node accessed into a local network supports recertification; if the mobile node supports the recertification, obtaining a recertification main session key (rMSK) generated according to recertification materials of the mobile node; generating paired main keys (PMK) according to the rMSK; and carrying out the mutual certification according to the PMK and the mobile mode. The invention can avoid the impaction of the prior standard frame and the large-scale update reconstruction of a network device, in particular to the authentication device, effectively shorten recertification time delay and reduce the realization complexity of the recertification.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a re-authentication method, system and authentication device. Background technique [0002] With the development of technology, modern communications have higher and higher requirements for mobility. Current mobile communications require terminals to communicate normally in mobile or roaming scenarios. The so-called mobility means that the access point (Attach Point, AP) of the terminal changes along with the movement of the terminal. A series of steps need to be performed for a terminal to move from an old access point to a new access point, including: leaving the original access point, performing new access authentication, and establishing a corresponding configuration relationship at the new access point. During the period when the terminal switches from the old access point to the new access point, the communication will be temporarily interrupted or delayed. For some servi...
