Security and efficiency of rekeying are crucial
requirements for multicast key management. However,
the two requirements pull in different directions and
balancing them to meet the application needs is still an
open issue. In this paper we introduce a Hybrid Key
Tree scheme to balance security, namely the resistance
to collusion, and the efficiency. The resistance to
collusion is measured by an integer parameter. The
communication and the storage requirements for the
controller depend on this parameter too, and they
decrease as the resistance to collusion is relaxed. We
analytically evaluate the efficiency of our scheme and
compare with the previous work. The results show that our
scheme allows a fine-tuning of security requirements versus
efficiency requirements at run-time, that is not possible with
the previous key management schemes.
