  • Method and system for handover authentication
    Patent number: 8131296
    Abstract: A handover authentication method includes performing, by a wireless network server, a first authentication between a client and the wireless network server via a first network gateway; obtaining first authentication keys for the wireless network server and the client based on the first authentication; determining, by the wireless network server, a need to handover the client from the first network gateway to a second network gateway; deriving, by the wireless network server and from the first authentication keys, a handover authentication key shared by the client and the wireless network server; obtaining, by the wireless network server, second authentication keys for the network server and the client; and serving, by the wireless network server, the client via the second network gateway.

  • Key management system and method for wireless networks
    Publication number: 20090110196
    Abstract: A key management method for wireless networks is disclosed. Before a mobile station residing in a first ASN switches to a neighboring second ASN, an authentication process between the mobile station and the second ASN is implemented. Thus, the authentication process is not required when the mobile station is switching to the second ASN.
