Abstract: A method and apparatus for generating a cryptosync is disclosed that generates a cryptosync with the desired variability without the overhead in complexity and size of prior cryptosyncs. The cryptosync is generated from a combination of fields including fields relating to the segmentation and reassembly of the data packets at a transmitting terminal and a receiving terminal. The resultant cryptosync does not repeat during the use of a particular security key.

Abstract: A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.

Abstract: Disclosed is a method for multiple EAP-based authentications in a wireless communication system. In the method, a first master session key (MSK) is generated in a first EAP-based authentication for a first-type access. A first temporal session key (TSK) is generated from the first master session key (MSK). A second EAP-based authentication is performed, using the first temporal session key (TSK), for a second-type access. First-type access and second-type access are provided after the first and second EAP-based authentications are successfully completed.

Abstract: Depending on channel conditions, a variable abort timer can be set in relation to wireless communication of data packets. Additionally, available buffer size can be evaluated and used to set a length of the variable abort timer. When a packet sequence is sent, packets can become lost in communication. When a lost packet is recognized, the timer can be initiated and a request for re-transmission of the lost packet can is sent. If the lost packet does not arrive during running of the variable abort timer, then the packet sequence can be processed without the missing packet.

Abstract: Systems and methods for switching among heterogeneous networks and inter-working between a source access system and a target access system. An inter-system handoff control component can facilitate setting an IP tunneling by the mobile unit, wherein IP addresses for inter-working security gateway and Radio Access Network of the target access system can be identified. The inter-system handoff control component can then implement tunneling between the source system and the target system, wherein signaling/packeting associated with the target system can be transferred over the source system.
