Given a plurality of data storage devices, the system establishes an encryption key for the plurality of data storage devices. The system locally stores the encryption key in a piecewise manner throughout the plurality of data storage devices such that the encryption key is rendered undeterminable with less than a threshold subset of the plurality of data storage devices. This results in the plurality of data storage devices being self encrypting. Upon an increase or decrease in the plurality, the system resplits the encryption key and locally stores the resulting pieces throughout the changed (increased/decreased) plurality of data storage devices. This renders the encryption key undeterminable with less than a new or revised threshold each time the plurality is changed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Local keying for self-encrypting drives (SED)","description":"A method and system self encrypts a disk storage device.
