A system and equipment for establishing a security association are also provided by the present invention.
A security association may be established between the wireless data network module and a wireless data network.
The second network element uses the connection-specific security association to decrypt/decode the MAP message.
The agreed key is tied to an authentication procedure to provide a security association that supports reuse of the key.
A security association can be established during a first session between the devices via an asymmetric key exchange (132).
It is assumed that there is a pre-established security asociation between the visited GW (230), which can be the visited AAA server, and the agent (210).
Provided the first and second servers can establish a conventional IP-type SA (e.g. using IPSec or TLS), there is a chain of secure associations between the two devices.
The first station and the second station will have previously established a security association (SA) with a topology control point (PCP).
A security association is established between the endpoints for the communication session on a connection (11) via the first communication network (20).
The KS receives a group ID and a Security Association, SA, policy list supported by a GM sent by the GM.
The invention relates to a method, which comprises initiating the establishment of a security association between a client node and a gateway node.
This chain is then used to build a new secure association between originating device and target Device.
The present invention provides a method for communication involving a supplicant, an authenticator, and an authentication server having an established security association based on a first key.
The messages transmitting the public keys are also secured using a security association for the routing links between the access terminal and the access router.
