Abstract
In an example embodiment, a key generation system (KGS) is used to generate private pairwise keys between peers belonging to a group. Each member of the group is provisioned with a set of parameters which allows each member to generate a key with any other member of the group; however, no group member can derive a key for pairings involving other group members. The private pairwise keys may be used to derive session keys between peers belonging to the group. Optionally, an epoch value may be employed to derive the private pairwise keys.
