Method and apparatus for storing and distributing encryption keys

A method of key distribution includes generating, by a first system device (101), key material and forwarding the key material from the first system device (101) to a second system device (107). It is determined whether a mobile station (401), for which the key material is directed, is active on the system. When the mobile station is active, the key material is forwarded to a base station (115) where the mobile station (401) is active, and the base station (115) forwards the key material to the mobile station (401).
