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;

    switching a second service application process from a first state to a second state, the second service application being selected for taking over service currently provided from the first service application process, the first state and the second state each being associated to a set of rights in the cluster;

    generating a private key for the second service application process based on the second state of the second service application process; and

    wherein the set of rights associated to the second state of the second service application process allows the second service application process to replace the first service application process for providing secure communications between the second service application and other service application processes in the HA cluster as provided prior the detection of the unavailability of the first service application process.
