SECURE CLOUD-BASED STORAGE OF DATA SHARED ACROSS FILE SYSTEM OBJECTS AND CLIENTS |
| 摘要 |
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. |

1. A method of storing file system data, comprising:
determining for an object associated with a plurality of component chunks of file system data a primary encryption key; using the primary encryption key 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; and providing the respective chunk keys 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. |
