Abstract
A storage-based secure communication system enables communication between a production site and a cyber recovery vault on a data replication facility. A control file is created in a controller-based file system that is accessible to both the production site and the cyber recovery vault. A communication subtask at the production site writes heartbeat and control information to the control file, encrypts the control file using the cyber recovery vault's public key, and digitally signs the control file using the production site's private key. A communication subtask at the cyber recovery vault reads the control file, decrypts the control file using the cyber recover vault's private key, and verifies the digital signature using the production site's public key. If the control file is determined to be valid, the control information contained in the control file is used to update the configuration of the cyber recovery vault on the data replication facility.
