Systems and methods for providing secure multicast intra-cluster communication
First Claim
1. A method for providing secure multicast communication capabilities to a plurality of nodes of a cluster, the method comprising:
- performing a mutual authentication between a node joining the cluster and any single node validly part of the cluster comprising calculating, separately for a session associated with the mutual authentication, a verifier using cluster credentials possessed by the node joining the cluster and all nodes validly part of the cluster including the node of the cluster performing the mutual authentication;
determining whether the mutual authentication is successful; and
communicating a cluster secret to the node joining the cluster using a secure communication channel unique to the mutual authentication session when the mutual authentication is determined to be successful, wherein the cluster secret renders the node joining the cluster a cluster node and enables the cluster node to securely communicate with every other node which is validly part of the cluster.

Abstract
Systems and methods which facilitate secure multicast communications between any valid node of a cluster using authentication between a node joining the cluster and any single node which is validly part of the cluster are disclosed. In accordance with embodiments, a cluster key is utilized to provide security with respect to intra-cluster communications. The cluster key of embodiments is shared by a node which is already part of the cluster with a node joining the cluster only after these two nodes mutually authenticate one another. The mutual authentication handshake of embodiments implements a protocol in which a session key is calculated by both nodes, thereby providing a secure means by which a cluster key may be shared. Having the cluster key, each node of the cluster is enabled to securely communicate with any other node of the cluster, whether individually (e.g., unicast) or collectively (e.g., multicast), according to embodiments.

8. A method comprising:
-
performing a mutual authentication handshake between a first node of a cluster and a second node of the cluster comprising calculating, separately for a session associated with the mutual authentication handshake between the first node and the second node, a verifier using cluster credentials possessed by the first node and the second node; communicating a cluster key between the first node and the second node using a secure communication channel established by the mutual authentication handshake between the first node and the second node; performing a mutual authentication handshake between a third node of the cluster and one of the first node or second node comprising calculating, separately for a session associated with the mutual authentication handshake between the third node of the cluster and one of the first node or the second node, a second verifier using cluster credentials possessed by the third node and at least one of the first node or the second node; communicating the cluster key between the third node and the one of the first node and second node using a secure communication channel established by the mutual authentication handshake between the third node and the one of the first node and the second node; and performing secure cluster communications between the first node, the second node, and the third node using the cluster key. - View Dependent Claims (9, 10)

11. A system, comprising:
a processor coupled to a memory and configured to execute programmed instructions stored in the memory to perform steps comprising; performing a mutual authentication between a node joining a cluster of nodes and any single node validly part of the cluster comprising calculating, separately for a session associated with the mutual authentication, a verifier using cluster credentials possessed by the node joining the cluster and all nodes validly part of the cluster including the node of the cluster performing the mutual authentication; determining whether the mutual authentication is successful; and communicating a cluster secret to the node joining the cluster using a secure communication channel unique to the mutual authentication session when the mutual authentication is determined to be successful, wherein the cluster secret renders the node joining the cluster a cluster node and enables the cluster node to securely communicate with every other node which is validly part of the cluster. - View Dependent Claims (12, 13, 14, 15, 16, 17)
