Abstract:
1. A method for providing secure communications in a High Availability (HA) cluster, the method comprising the steps of: detecting an unavailability of a first service application process associated with a service, the first service application process being further associated with a first key pair having a public key and a private key; selecting a second service application process to provide the service associated with the unavailable first service application; switching the selected second service application process from a first state associated with a first set of rights in the HA cluster to a second state associated with a second set of rights in the cluster providing authorization to replace the first service application; and generating a private cryptographic key for the second service application process based on the second state of the second service application process and the public key associated with the first service application process to create a second key pair, the second key pair being composed of the generated private cryptographic key and the public key, to enable secure communications between the second service application process and other service application processes in the HA cluster.
