Abstract :
In this paper, a collusion-resistant matrix system (CRMS) for group key managements is presented. The CRMS is defined as a collection of subsets of users, and the keys held by users in CRMS are organized in a hierarchical matrix manner. After describing the join and leave protocols, we prove that CRMS has lceil2N/trceil-collusion resistant capability. Moreover, the suggestion of how to select the parameters in CRMS is given. The simulated experiments show that CRMS is a practical group key management in wireless networks.
