Secure data parser method and system
View Patent ↗A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data that may be communicated using multiple communications paths.
1. A secure storage network comprising:
a plurality of physical storage devices storing thereon a plurality of shares, the plurality of shares being associated with at least one session key used to secure a dataset; and
a secure storage system configured to:
present to a client device a virtual disk, the virtual disk comprising a directory mapped to the plurality of physical storage devices such that physical locations of the shares are hidden from the client device;
generate the plurality of shares for storage on the plurality of physical storage devices by performing a securing operation on the dataset received from the client device and distributing the dataset in the shares;
include with each of the plurality of shares data indicative of the at least one session key used to secure the dataset; and
reconstitute the dataset from at least a portion of the plurality of shares stored on the physical storage devices in response to a request from the client device for information in the dataset.
2. The secure storage network of claim 1 , wherein the secure storage system is further configured to generate the plurality of shares by performing a cryptographic operation on the dataset.
3. The secure storage network of claim 1 , further comprising a key management server configured to store workgroup keys.
4. The secure storage network of claim 1 , wherein the secure storage system is further configured to provide access to the reconstituted dataset.
5. The secure storage network of claim 1 , wherein the secure storage system is further configured to establish a secure connection between the client device and the secure storage system.
6. The secure storage network of claim 1 , wherein the shares contain a substantially random distribution of the received dataset.
7. The secure storage network of claim 1 , wherein the secure storage system is configured to reconstitute the received dataset from fewer than all of the shares.
8. The secure storage network of claim 1 , wherein the secure storage system is configured to secure the dataset by encrypting the dataset using the at least one session key.
9. The secure storage network of claim 1 , wherein the secure storage system is configured to secure the dataset by splitting the dataset using the at least one session key.
10. The secure storage network of claim 1 , wherein the data indicative of the at least one session key comprises: a portion of the at least one session key or data indicative of a portion of the at least one session key.
11. A secure storage system comprising:
a programmed hardware processor configured to:
present to a client device a virtual disk, the virtual disk comprising a directory mapped to a plurality of physical storage devices such that physical locations of a plurality of shares are hidden from the client device;
generate the plurality of shares for storage on the plurality of physical storage devices by performing a securing operation on a dataset received from the client device and distributing the dataset in the shares;
include with each of the plurality of shares data indicative of at least one session key used to secure the dataset; and
reconstitute the dataset from at least a portion of the plurality of shares stored on the physical storage devices in response to a request from the client device for information in the dataset.
12. The secure storage system of claim 11 , wherein the programmed hardware processor is further configured to generate the plurality of shares by performing a cryptographic operation on the dataset.
13. The secure storage system of claim 11 , wherein the programmed hardware processor is further configured to provide access to the reconstituted dataset.
14. The secure storage system of claim 11 , wherein the programmed hardware processor is further configured to establish a secure connection between the client device and the secure storage system.
15. The secure storage system of claim 11 , wherein the shares contain a substantially random distribution of the received dataset.
16. The secure storage system of claim 11 , wherein the programmed hardware processor is configured to reconstitute the received dataset from fewer than all of the shares.
17. The secure storage system of claim 11 , wherein the data indicative of the at least one session key comprises: a portion of the at least one session key or data indicative of a portion of the at least one session key.
