STORAGE SECURITY USING CRYPTOGRAPHIC SPLITTING |
摘要 |
Methods and systems for securing data in a data storage network are disclosed. One method includes receiving at a secure storage appliance a block of data for storage on a volume, the volume associated with a plurality of shares distributed across a plurality of physical storage devices. The method further includes cryptographically splitting the block of data received by the secure storage appliance into a plurality of secondary data blocks, and cryptographically splitting the session key into a plurality of session key fragments. The method further includes encrypting each of the plurality of secondary data blocks with a different session key, each session key associated with at least one of the plurality of shares, and encrypting each of the plurality of session key fragments with a workgroup key associated with a source of the block of data. |
