ABSTRACT:
In a communication system wherein a serving controller may be configured to support a first security mechanism and at least one other security mechanism. A request for registration is sent from a user equipment to the serving controller where after it is determined in a second controller that the user equipment supports another security mechanism than the first security mechanism. The second controller may then send to the serving controller an indication that another security mechanism than the first security mechanism is used by the user equipment. The serving controller then sends a challenge in accordance with the other security mechanism to the user equipment.
