SECURELY RECOVERING STORED DATA IN A DISPERSED STORAGE NETWORK |
| 摘要 |
A method for execution by a dispersed storage and task (DST) execution unit that includes a processor includes receiving a slice pre-image request from a computing device via a network that indicates a data slice, a requesting entity and a plurality of storage units. A data pre-image is generated by performing a pre-image function on the data slice based on the plurality of storage units. An encrypted data pre-image is generated for transmission to the computing device by performing an encryption function on the data pre-image based on a key associated with the requesting entity. |

1. A method for execution by a dispersed storage and task (DST) execution unit that includes a processor, the method comprises:
receiving a slice pre-image request from a computing device via a network, wherein the slice pre-image request indicates a data slice, a requesting entity, and a plurality of storage units; generating a data pre-image by performing a pre-image function on the data slice based on the plurality of storage units; and generating an encrypted data pre-image for transmission to the computing device by performing an encryption function on the data pre-image based on a key associated with the requesting entity. |
