A computer-implemented method includes sending key group information to a storage system. The key group information includes keyID information for client data keys in the key group. The client data keys enable deduplication of data chunks encrypted in any of the client data keys in the key group. The method also includes generating deduplication information. The deduplication information includes fingerprints associated with chunks of client data. The method also includes encrypting the data chunks with one of the client data keys, wherein a corresponding decryption key for the encrypted data chunks is not available to the storage system. The method includes sending the deduplication information to the storage system for use in a deduplication process by the storage system and sending the encrypted data chunks to the storage system.
