Abstract
A method for operating with KMFs includes a communication device having a memory device: receiving a designation of a primary KMF for the communication device, wherein only one primary KMF is designated for the communication device at any given time instance; receiving a designation of a secondary KMF for the communication device; storing, within the memory device, a first and a second set of crypto groups, wherein each crypto group within each set of crypto groups comprises at least one keyset, wherein each set of crypto groups is associated, within the memory device, to only one KMF identifier; associating, within the memory device, the first set of crypto groups to an identifier for the primary KMF; and associating, within the memory device, the second set of crypto groups to an identifier for the secondary KMF.
