Abstract

A secure real-time data replication system includes a key management server that provides keys to hosts that store encrypted data. Data to be written in one host is encrypted using a key received from the key management server; the encrypted data is stored in the host. A copy of the data is provided to another host for real-time data replication. In the other host, the copy of the data is encrypted using another key received from the key management server; the encrypted copy of the data is stored in the other host. Keys are provided by the key management server based on policy rules governing the keys.
