Abstract:
A method for securing data in a data cluster is performed by a data manager of a data cluster. The method includes receiving, by a data cluster, a write request for a user to write data to the data cluster, wherein the write request comprises an object identifier (OID) associated with data and a user identifier (UID) associated with the user; sending, to a key manager, an intermediate key request, wherein the intermediate key request comprises the UID; receiving, by the data cluster from the key manager, an intermediate key; processing the data to obtain a plurality of chunks and metadata associated with the plurality of chunks; generating an encryption key using the intermediate key and the OID; encrypting the metadata using the encryption key to generate encrypted metadata; deleting, after generating the encrypted metadata, the encryption key; and storing the encrypted metadata and the plurality of chunks in the data cluster.
