MESSAGE-BASED DATABASE REPLICATION

Abstract:

A networked device communication system can configure network devices (e.g., a primary and secondary database) to send and receive sequences of messages, such as replicated data, using one or more keypairs and wrapping keys. The sequences of messages can include an initial set of messages that are encrypted by a wrapping key, and further include another set of messages that are encrypted by a replaced staggered key. The sequence of messages can be configured to be decrypted without exporting keys of hardware security modules.
