Abstract:
Techniques to provide secure cloud-based storage of data shared across file system objects and clients are disclosed. In various embodiments, a primary encryption key is determined for an object associated with a plurality of component chunks of file system data. The primary encryption key is used to generate for each of said component chunks a corresponding chunk key, based at least in part on the primary encryption key and data comprising or otherwise associated with the chunk. The respective chunk keys are provided to a file system client configured to create and store the object at least in part by encrypting each chunk included in the plurality of component chunks using the chunk key provided for that chunk to generated encrypted chunk data, and combining the encrypted chunk data to create and store the object.

Claim (Index 11):
A system, comprising:\n a communication interface; and a processor coupled to the communication interface and configured to:\n compute a corresponding chunk hash value for each of a plurality of component chunks of file system data associated with an object, wherein the corresponding chunk hash value is based on at least a portion of data stored in the corresponding component chunk; \n determine a primary encryption key for the object, wherein the object is comprised of the plurality of component chunks; \n use the primary encryption key to generate, for each of said plurality of component chunks, a corresponding chunk key, wherein the corresponding chunk key is based at least in part on the primary encryption key and the corresponding chunk hash value associated with the corresponding chunk; and \n provide chunk keys of the plurality of component chunks associated with the object, via the communication interface, to a file system client, wherein the file system client is configured to encrypt each chunk included in the plurality of component chunks using a chunk key provided for that chunk.
