Abstract
A system is provided for performing secure key exchange between a plurality of nodes of a communication network. The system comprises a master node and at least two slave nodes. In this context, the master node is configured to authenticate the at least two slave nodes with a pair-wise authentication key corresponding to each pair of master node and slave nodes. The master node is further configured to generate a group authentication key common to the plurality of nodes. Furthermore, the master node is configured to encrypt the group authentication key with the pair-wise authentication key for each respective pair of master node and slave nodes, thereby generating a respective encrypted group authentication key. Moreover, the master node is configured to communicate the encrypted group authentication key to the respective slave nodes.
