Abstract
A first entity initiates a first connection to a second entity which then receives from the second entity initial information which the first entity uses to derive a key for the first entity (first entity key). The first entity key is then used to authenticate the second entity and if the second entity is authenticated then the first entity derives a second key which is used for communication between the first entity and the second entity.
